Firmware 09.09.09 is the latest firmware released for the HP M-series Edge Switches and Directors. This firmware is common for all M-series fabric products, except the McDATA 4Gb SAN Switch for HP p-Class BladeSystem, which has separate firmware. The firmware is available on the following HP website: http://h18006.www1.hp.com/storage/networking/index.html Select Retired Products, navigate to your switch model, and then select Download drivers and software. For more information about upgrading firmware versions, see the appropriate Director or Edge Switch service manual.
Operating multiple switches in a fabric topology is subject to topology limits. Consider the impact of the following topology limits when planning the fabric: Fabric elementsEach fabric element is defined by a unique domain ID that ranges from 1 to 31; therefore, the theoretical limit of interconnected Directors in a single fabric is 31. The supported limit of interconnected switches in a single fabric is 24. The supported limit of interconnected switches in a single fabric can be increased to 31, provided that any Edge Switch 2/32, or Director 2/64 in the fabric is deployed at the edge of the fabric. However, because this is subject to change, contact your HP-authorized service representative for the current number of interconnected switches supported in a single fabric. Heterogeneous fabricTo determine if interoperability is supported for a product, or if restrictions apply, see the product publications or contact your HP-authorized service representative. Number of interswitch links (ISLs)The maximum number of ISLs supported is 75% of installed ports for the Director 2/64, and 100% of installed ports for the Director 2/140. The maximum number of ISLs supported for Edge Switches is all available switch ports. For redundancy, at least two ISLs should connect any two Edge Switch or Director-class fabric elements. Because this inform-
ation is subject to change, contact your HP-authorized service representative for the current number of ISLs supported for each Edge Switch or Director. Hop countThe hop count is equal to the number of ISL connections traversed in a single path, not the total number of ISL connections between devices. The Fibre Channel theoretical limit of ISL connections traversed (hop count) in a single path through a fabric is seven. The maximum supported hop count in a single path through a fabric is three. Because this information is subject to change, contact your HP-authorized service representative for the current hop count supported by a single fabric path. NOTE: For more information about planning the fabric, see the HP StorageWorks SAN design reference guide, available on the following HP website: http://www.hp.com/go/SANdesignguide
Consider the following switch cable requirements: For cables measuring up to 500 meters (1 Gb/s) or 300 meters (2 Gb/s), use multimode Fibre Channel cables. For longer cables, use single-mode Fibre Channel cables. Multimode optical cables are connected to short-wave optical transceiver modules in a switch. Single-mode optical cables are connected to long-wave optical transceiver modules in a switch. Multimode cables should use 50/125 optical fibers; single-mode cables typically use 9/125 optical fibers for distances up to 10 km. Verify that connectors interfacing with the Edge Switch or Director products use LC duplex connectors with a PC finish. The connector at the opposite end of the cable must be of either LC or SC type, depending on the requirements of the connected device.
For a list of supported operating systems, see the HP StorageWorks SAN design reference guide, available on the following HP website: http://www.hp.com/go/SANdesignguide
Table 2 lists issues that have been fixed since the release of firmware 09.09.08. Table 3 lists issues that have been fixed since the release of firmware 09.09.00. Table 2 Fixes in this release Description
The Wind River embedded debugger is enabled by default, exposing a CERT vulnerability allowing access to certain debug capabilities if one also had physical access to the switch. The debugger should be disabled by default.
Edge Switch 2/12, Edge Switch 2/24, Director 2/140
Table 3 Fixes since firmware release 09.09.00 Description
When an Access Gateway device was connected to a standalone switch, HAFM Basic (the embedded switch GUI) showed the connected device as offline with a reason of Blocked temporarily, internal. Mixed fabrics (with B-series and M-series/McDATA switches) operating in IM2 interop (McDATA Fabric ) mode did not support Frame Redirect zones with the default zone enabled. This restriction was removed. In nonrestartable Frame Redirection mode, if a virtual initiator was taken offline, a route still existed between the physical host and target. In an environment involving routed fabrics and encryption, where one or both of the edge fabrics was an M-series/McDATA Interop fabric, if an initiator was attached directly to an M-series/McDATA switch in the edge fabric, the host could lose access to imported targets in the event the encryption switch went offline and then back online. RSCN was not sent to physical Host and Target for Virtual Initiator and Virtual Target state changes when Frame Redirection Virtual Initiator/Virtual Target were part of a regular zone set. Using restartable Frame Redirection, when just the virtual initiator was taken offline, the virtual target PID was sent to the host in the RSCN instead of the target PID. In an IM3 (McDATA Open Fabric ) mode fabric where both the host and target were connected to M-series/McDATA switches, and the Frame Redirection policy is nonrestartable, routes still existed from host to target when a virtual initiator was taken offline. A Virtual Initiator responded to physical target query even when the Virtual Target was down. With Virtual Target offline, GID_PN or GID_NN name server queries would return Virtual Initiator PID instead of Host PID. With a Virtual Initiator offline, the GNN_ID, GID_PN and GID_NN name server query responses all returned values to the host when they should have been rejected. With Virtual Initiator offline, the GID_PN and GID_NN name server query responses both returned the Virtual Target PID to the host instead of the target PID.
All All All All
The error message Blocked Temporarily, internal was shown for devices on switch ports after a Power On Reset when the error message should have been Blocked due to special (RD) zone. After upgrading firmware to 09.09.06, CTP faults could be encountered (events 410, 414, and 411), and C0 faults could occur followed by the CTP coming back online. This only happened when an IP source was sending the switch an ICMP redirect packet over TCP/IP. Events with code 411 could be posted with OSMS faults with 153C2, 153C3 and 153AB codes due to internal race conditions when a M-series/McDATA switch was in a fabric with B-series switches. While processing a GPSC command, OSMS faulted with code while clearing internal database. Routes were not being set up correctly when running Frame Redirection over Fibre Channel Routing, causing a host attached to the switch not to see the target. Event 159 Frame Redirect Deactivated event messages were reported during an IML (initial machine load) even when Frame Redirection was not enabled. Error counter statistics were not maintained correctly in 4Gb QPM port cards. The C3 Discard frames counter increased continuously even though no frame drops occurred. In a mixed M-series and B-series fabric including an Encryption Switch, when a configuration save or change on the Encryption Switch redirect zones was performed, hosts connected the Director 2/140 lost access to their storage if also connected to the Director 2/140, for 10 seconds or more. A switch was blocking a PLOGI accept on the remote end because the near end did not send SW_RSCN before PLOGI. This resulted in slow server bootup. When Frame Redirection (FR) was used in a mixed M-series and B-series fabric, and there were virtual targets (VT) that were either NPIV or loop devices connected to the same physical port, and a host port was a member of two different FR zonesthat each included a virtual target (VT1 and VT2) on the same physical port, if the connection between the host and VT1 was interrupted, then the connection between that host and VT2 might also have been interrupted. If a port received a frame with an invalid source ID (SID), the port would not appear as a logged-in port, even though traffic was not disrupted. The Director was reporting an incorrect port status. In a FICON environment, the Director would provide an incorrect Interface Protocol Type for Node Selector 0 in response to the inband query Read Node Identifier. Due to an internal error, some switches encountered Event 411, Firmware Fault, with Fault Code 00000073. Audit log entries showed the HAFM/EFCM server IP address as 0.0.0.0 Zone activation could fail for fabrics with a large number of zones.

This section provides firmware installation information.
Prerequisites for installing and using firmware 09.09.09
Consider the following prerequisites for firmware 09.09.09: Before you install the new firmware, HAFM should be at the minimum level. Before you upgrade to firmware 09.09.09, EFCM must be at 09.07.00 or later if you are using EFCM to manage Edge Switches or Directors. DCFM Enterprise or DCFM Professional Plus version 10.3.0 or later is recommended for managing Edge Switches or Directors. HAFM cannot configure the McDATA 4 Gb/s Intrepid 6000 QPM when installed in a Director 2/64. The QPM can be configured using HAFM Basic or the CLI. McDATA EFCM 9.0 or later can configure the QPM when installed in a Director 2/64. If you are using HAFM to upgrade firmware, an Edge Switch 2/24 must be managed with HAFM 08.08.00 or later before upgrading to firmware 08.xx.xx or later. If you upgrade to firmware 08.xx.xx or later using an HAFM release earlier than 08.08.00, the upgrade may fail. Firmware 08.01.00 introduced slightly more processor utilization, which can cause the download to occasionally exceed HAFM's timeout. As an alternative to HAFM, use the switch's HAFM Basic interface (formerly EWS) to upgrade firmware. Firmware upgrades or downgrades should not be performed using HAFM Basic from Internet Explorer 5.00.3315.1000x. The download operation may not complete and may eventually time out, leaving the switch with the previous version of firmware. All Edge Switches and Directors in the same fabric should have the same firmware version installed. Although products can coexist in a fabric running different versions of firmware, all products must be at the same major functional release version.
Upgrading from an earlier version of firmware
Upgrading to firmware 09.09.09 is nondisruptive to attached devices. The Edge Switch or Director is not required to be offline before performing an upgrade operation. Limitations to performing an upgrade operation are clearly identified. Consider the following when upgrading firmware: Before upgrading firmware, HP recommends that you back up the Edge Switch or Director configuration. See the HP StorageWorks Director Element Manager user guide for more information. HAFM Basic also provides an option to print or save the product configuration to a file. See the HAFM Basic user guide for more information. All products must be running firmware 09.07.02 or later before upgrading to 09.09.09. If a switch is operating with firmware earlier than 09.07.02, you must upgrade to 09.07.02 or 09.08.01 before installing 09.09.09. Upgrades and downgrades are supported only within a functional release, such as 09.07.02 to 09.08.01, or from one functional release to the next, such as 09.03.00 to or from 09.06.02, or 09.06.02 to or from 09.08.01.
NOTE: The following HP firmware versions are considered to be within one functional release: 09.09.09, 09.09.08, 09.09.06, 09.09.05, 09.09.03, 09.09.02, 09.09.00 09.08.03, 09.08.01, 09.07.02 09.06.02 09.03.00, 09.02.00, 09.00.00 08.02.00, 08.01.01, 08.01.00 07.01.03, 07.01.02, 07.00.00 If you use HAFM Basic for upgrades and downgrades, and the release version rule is not followed, errors will occur and there may be a disruption to attached devices. If upgrading firmware requires an upgrade from 04.xx.xx to 05.xx.xx, there are special considerations, as described in Upgrading firmware on a Director from 04.xx.xx to 05.xx.xx on page 11. If upgrading firmware requires an upgrade from 06.xx.xx, upgrade from 06.xx.xx to 07.01.03. Firmware 07.01.03 includes a fix to an issue that can occur under very specific conditions when firmware is upgraded from 06.xx.xx to 07.xx.xx. Other versions of 07.xx.xx should not be used in the upgrade process. If upgrading firmware requires an upgrade from 07.xx.xx, upgradehahm from 07.xx.xx to 08.02.00. Firmware 08.02.00 includes a fix to an issue that can occur when firmware is upgraded from 07.xx.xx to 08.xx.xx for the Edge Switch 2/24 and Edge Switch 2/12. Other versions of 08.xx.xx should not be used in the upgrade process. Some customer environments use application or host software that is affected by the restart of the Director CTP during a HotCAT download operation. Applications that rely on inband management servers are especially prone to problems caused by processor restart. For example, an application may be configured to poll the Edge Switch or Director at regular intervals. The polling process could occur during a restart period, causing the application software to react adversely. As a solution, before the upgrade, shut down the applications driving inband requests, and then restart the applications after the upgrade is complete.
Upgrading firmware on a Director from 04.xx.xx to 05.xx.xx
An issue has been identified in firmware 04.xx.xx if the contents of the nonvolatile random access memory (NVRAM) on the active CTP are corrupted. Once the configuration has been loaded, the corruption is not detected until an IPL/IML, power cycle, or firmware code load. If the NVRAM on the active CTP has corrupted contents, the firmware load can cause the configuration to reset to factory defaults, which can cause a system outage. By using the following procedure to upgrade firmware, the configuration is preserved and a system outage is avoided. This issue has been resolved with firmware 05.02.00-13 and later. NOTE: You must have maintenance authorization rights to access the HAFM Product/Element Manager menu options used in this procedure.
To safely upgrade firmware on a Director: 1. 2. 3. Upgrade the HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum). Download firmware 05.02.00-13 by selecting Firmware Library from the Product Manager Maintenance menu. Back up the Director configuration by selecting Backup & Restore Configuration from the Product Manager Maintenance menu. NOTE: Step 4 is not required if you are upgrading from 05.xx.xx or later. 4. Using the Product Manager, execute a CTP swap: a. b. c. From the Product/Element Manager Hardware view, verify that the amber LED is not illuminated for either CTP card. Right-click the CTP card that you believe is active, and then select FRU Properties. Verify that this is the active CTP card. Right-click the active CTP card, and then select Switchover. The Director loses its Ethernet connection for a short time during the switchover process. When switchover occurs, the green LED illuminates on the backup CTP card to indicate that it is now the active card. 5. Upgrade the firmware to 05.02.00-13 on each Director by selecting Send in the Firmware Library dialog box.
Upgrading firmware on an Edge Switch from 04.xx.xx to 05.xx.xx
An issue has been identified in firmware 04.xx.xx if the contents of the NVRAM on the CTP are corrupted. Once the configuration has been loaded, the corruption is not detected until an IPL/IML, power cycle, or firmware code load. If the NVRAM on the CTP has corrupted contents, the firmware load can cause the configuration to reset to factory defaults, which can cause a system outage. Edge Switch products already running 05.01.00 or later continually validate the NVRAM configuration, so risk of an outage is extremely low. For Edge Switch products running an earlier version of firmware, the risk of an outage increases due to the NVRAM issue. If an outage compromises system integrity, HP recommends that the Edge Switch firmware upgrade be a scheduled maintenance action that anticipates the failure of switch connectivity. This issue has been resolved with firmware 05.02.00-13 and later. To safely upgrade firmware on an Edge Switch: 1. 2. 3. 4. Upgrade the HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum). Download firmware 05.02.00-13 by selecting Firmware Library from the Product Manager Maintenance menu. Back up the Edge Switch configuration by selecting Backup & Restore Configuration from the Product Manager Maintenance menu. Upgrade the firmware to 05.02.00-13 on each Edge Switch by selecting Send in the Firmware Library dialog box.
Considerations for downgrading the firmware version
Edge Switches or Directors are not required to be offline before performing a firmware downgrade operation. Limitations to performing a downgrade are clearly identified. Before downgrading firmware, HP recommends that you back up the Edge Switch or Director configuration. See the Director or Edge Switch Element Manager user guide for more information. EWS (HAFM Basic) provides an option to print or save the product configuration to a file. See the HAFM or EFCM Basic user guide for more information. Consider the following when downgrading firmware: All installed QPM cards must be removed from the Director 2/140 if downgrading to a version earlier than 09.00.00. All installed QPM cards must be removed from the Director 2/64 if downgrading to a version earlier than 09.01.00. All trial PFE key features must be disabled before downgrading to a version earlier than 09.00.00. The domain ID offset must be set to the default value 0x60 before downgrading to a version earlier than 09.00.00. WWN aliases will be disabled when downgrading firmware in any Edge Switch or Sphereon switch to a version earlier than 09.01.00. Downgrading directly to a version earlier than 09.07.00 from 09.09.09 is not allowed. To downgrade to a version earlier than 09.07.00, you must first downgrade to 09.08.01 or 09.07.02. Upgrades and downgrades are supported only within a functional release, such as from 09.07.02 to 09.08.01, or from one functional release to the next, such as from 09.03.00 to 09.06.02, or from 09.08.01 to 09.06.02. If HAFM Basic is used for upgrades and downgrades, and this rule is not followed, errors will occur and there may be a disruption to attached devices. For the procedures to download firmware to the Edge Switch or Director using the HAFM Element Manager interface or HAFM Basic interface, see the following: Edge Switch or Director installation and service manualProvides procedures for obtaining firmware from the HP website and downloading firmware to the Edge Switch or Director using HAFM Edge Switch or Director Element Manager online help and user guideProvides instructions for downloading firmware to the Edge Switch or Director using the HAFM interface HAFM Basic user guide and online helpProvides procedures for downloading firmware to the Edge Switch or Director
HAFM upgrade required for firmware 09.09.09
Consider the following HAFM requirements for firmware 09.09.09: If you are using the 1U rack-mount HAFM Appliance to manage the Edge Switch or Director, the minimum HAFM version required is 08.09.01. This HAFM software is provided on the HP StorageWorks HA-Fabric Manager documentation and software CD (Part Number 516-000024-720). This minimum version of HAFM allows you to manage Edge Switches or Directors running firmware 09.09.09. However, to manage all of the newer switch features and enhancements, you may upgrade to EFCM software 09.07.00. To migrate from HAFM to EFCM, you must first upgrade to HAFM 08.09.01. An upgrade kit for HAFM 08.09.01 (Part Number A7490A) is available for owners of a licensed version of HAFM. Contact your HP-authorized service representative to obtain a HAFM upgrade kit. This HAFM upgrade is also available on the following HP website: http://h18006.www1.hp.com/storage/networking/index.html Select Retired Products, navigate to your switch model, and then select Download drivers and software. HP recommends using DCFM Enterprise or DCFM Professional Plus version 10.3.0 or later to manage your M-series Edge Switches or Directors. You can migrate from an installation of EFCM 09.07.00 to DCFM Enterprise 10.3.0. Alternatively, you can perform the firmware upgrade directly to the Edge Switch or Director using the switch's HAFM Basic management interface. For more information about upgrading software versions, see the HP StorageWorks HA-Fabric Manager user guide.
M-series and B-series switch interoperability
For details on compatible firmware versions, management software EFCM or Data Center Fabric Manager (DCFM) Enterprise versions, and other requirements for M-series and B-series switch interoperability, see the latest application notes under Application Notes > Fabric Interoperability, available on the following HP website: http://www.hp.com/storage/spock
This section provides information that you should consider before using Edge Switches or Directors running firmware 09.09.09.
Master log does not display port number
For port offline and online messages in the Master log in HAFM or EFCM, the switch port number, switch WWN, and connected device (node) WWN should be included in the message. However, the switch WWN appears as the node WWN, and the node WWN is not included.
HAFM Basic issue with Mozilla browser
Access control list (ACL) IP entries are not validated in HAFM Basic when using Mozilla browser.
Default zone is disabled by default
The default zone on the Edge Switches and Directors is disabled by default. Zoning must be configured in order for devices connected to the Edge Switch or Director to communicate.
Some IP addresses must be avoided
If you use HAFM to manage Edge Switches and Directors, do not use IP addresses in the range 192.168.0.0 through 192.168.0.255. This subnet is used internally by the HAFM Appliance. Using an IP address in this range causes the Call Home feature to function incorrectly.
Using HAFM Basic
HAFM Basic requires Microsoft Internet Explorer version 6 or Netscape version 7 to operate correctly.

Using the same firmware version
All Edge Switches and Directors in the same fabric should have the same firmware version installed to ensure that the firmware operates correctly. Firmware 09.09.09 is common for all M-series fabric products, except the McDATA 4Gb SAN Switch for HP p-Class BladeSystem, which has separate firmware.
Reinstalling feature licenses
Feature licenses (or keys) must be reinstalled after performing a factory reset on an Edge Switch or Director to regain use of the licensed features (for example, SANtegrity Binding).
CTP controls port lights
Port lights on the Edge Switches and Directors are controlled by the CTP. Certain activities, such as firmware updates, IPLing the CTP, and switching over to the backup CTP (Director) can turn off the port lights momentarily until control is reasserted by the CTP. Fibre Channel traffic is not affected during these times.
Full Fabric capability for Edge Switch 2/12
Unlike other Edge Switch and Director products, a PFE key controls Edge Switch 2/12 E_Port-to-E_Port connections. After purchasing and installing the feature key, you can configure E_Port connections on any of the active ports. The feature key includes distance support. With firmware 06.00.00 or later, the Edge Switch 2/12 ships with five BB_Credits allocated to each port. After activation of the Full Fabric feature on the switch, each port has 12 BB_Credits allocated to support up to 12-km links at 2-Gb/s speed.
Support for speed autonegotiate
Autonegotiate is supported. However, HP recommends that E_Ports (ISLs) be set to a specific port speed (1 Gb/s, 2 Gb/s, or 4 Gb/s, as appropriate, for the speed of the Edge Switches or Directors being connected) instead of to Negotiate. Specifying a port speed decreases the fabric build time in response to a perturbation in the fabric. Specifying a port speed for N_Ports also decreases the fabric build time, but it is not required. Older HBA devices do not always succeed in logging in to a switch port when the port speed is set to Autonegotiate. Workaround: If an older HBA has difficulty logging in to a switch port with the port speed set to Negotiate, set the port speed to 1 Gb/s, 2 Gb/s, or 4 Gb/s, according to the operating speed of the HBA connected to that port.
SNMP object returns incorrect value
The SNMP object t11NsInfoSubsetTableLastChange does not return the proper value of the last change in the Name Server timestamp, but instead returns the value 0 days 00h:00m:00s.00th.
Preferred Path may be cleared when port card is replaced
When replacing a port card module, a configured Preferred Path with a source port that is part of the newly installed port card module is cleared. A configured Preferred Path with an exit port that is part of the newly installed port card module is not cleared. If the Preferred Path entry is cleared when a port card module is replaced, the Preferred Path must be reentered.
Devices in mixed fabric may not log in after power cycle if RD zones are configured
In a mixed fabric (containing both M-series and B-series switches) in McDATA Fabric interop mode, devices are unable to log in to an Edge Switch or Director that is Power On Recycled (POR) when RD zones are configured. This is evident when the name server database is empty and the F_Ports do not come online. To enable the devices to log in, either issue the cfgsave command from a B-series switch in the fabric, or delete the RD zones locally using the CLI.
Fabric initialization error may occur
A fabric initialization error may occur when a two-switch fabric has only one ISL between them, and the ISL is blocked and then unblocked. When this occurs, the fabric is not formed. To correct this, set one of the switches offline and then back online. This is disruptive to devices connected to the switch that is set offline, so you should plan accordingly.
Segmented ISL may be reported incorrectly in mixed fabric
B-series switches display a Gx_Port connection as Loopback (when they should display a segmented condition) for M-series Edge Switch 2/24 or McDATA Sphereon 4500, M4700, or M4400. To avoid this, configure the port as a G_Port (not a Gx_Port) when attaching to a B-series switch.
PDCM may revert to earlier configuration after power cycle
The PDCM configuration is set to the previously active configuration instead of the configuration in the IPL file when all of the following conditions apply: A switch is managed with HAFM/EFCM Management Style configured to FICON Management Style The Prohibit Dynamic Connectivity Matrix (PDCM) is configured with Active=Saved disabled The HAFM/EFCM Management Style is changed to Open Systems Management Style The switch is power-cycled
Workaround: If the switch is configured as described above, review and modify the PDCM as needed after a power cycle.
Ethernet port may become unresponsive
After upgrading firmware from 9.6.x or later, the Ethernet port may become unresponsive, which prohibits management of the switch.
Workaround: If you encounter this problem, remove the Ethernet cable from the port and then reconnect it. If this does not work, execute an IML by pushing the IML button on the switch, which resets the Ethernet port.
Open Trunking function may operate slower when Reroute Delay is enabled
When Open Trunking is in use, Reroute Delay is enabled, and traffic is rerouted by the Open Trunking function, the anticipated changes in data flow are not correctly accounted for in the Open Trunking algorithms. This can cause delays in rerouting traffic by Open Trunking.
Workaround: The slower rerouting of data by Open Trunking can be tolerated and corrects itself. This can be avoided by disabling Reroute Delay when using Open Trunking.
Devices may be blocked in mixed M-series and B-series fabrics using Frame Redirection
M-series switches in a fabric with B-series switches using Frame Redirection zoning may block all attached devices with the reason indication Blocked Temporarily, Internal. This can occur when users power-cycle the M-series switch while it is participating in a fabric with Frame Redirection zoning (a capability used for B-series application or encryption services).
Workaround: If the switch is still participating in the fabric with Frame Redirection, issue the cfgsave command from a B-series switch with the Frame Redirection zone in its defined zone database. If the M-series switch is no longer attached to the fabric with Frame Redirection zoning, issue the Config.Zoning.deleteSplZoneSet command via CLI to the M-series switch.
