Hitachi TrueCopy for z/OS
Hitachi TrueCopy for z/OS (TCz) includes both TCz Synchronous and TCz Asynchronous (TCzA). The TCz (formerly called TC390) feature of the storage system allows you to create and maintain remote copies of the data stored on the storage system for data backup and disaster recovery purposes. TCz provides synchronous and asynchronous copy modes to accommodate a wide variety of user requirements and data copy/movement scenarios.
You can perform TCz operations across distances of up to 30 km (18.6 miles) using single-mode longwave optical bre cables in a switch conguration. Long-distance solutions are provided, based on user requirements and workload characteristics, using approved channel extenders and communication lines. You can use TCz in conjunction with Siz to provide multiple copies of volumes at both your main (primary) and remote (secondary) sites. For more information, see section Combining Hitachi ShadowImage for z/OS with Hitachi TrueCopy for z/OS (TCz) on page 51 and the Hitachi TrueCopy for z/OS user guide for XP12000/XP10000 Disk Arrays and SVS 200.
Hitachi Universal Replicator for z/OS
HItachi Universal Replicator for z/OS (URz) provides a RAID storage-based hardware solution for disaster recovery which enables fast and accurate system recovery. Once URz operations are established over dedicated bre-channel remote copy connections, duplicate copies of data are automatically maintained for backup and disaster recovery purposes. During normal URz operations, the primary data volumes remain online to all hosts and continue to process both read and write I/O operations. In the event of a disaster or system failure, the secondary copy of data can be rapidly invoked to allow recovery with a very high level of data integrity. URz can also be used for data duplication and migration tasks. URz represents a unique and outstanding disaster recovery solution for large amounts of data which span multiple volumes. The URz group-based update sequence consistency solution enables fast and accurate database recovery, even after a rolling disaster, without the need for time-consuming data recovery procedures. The URz journal groups (volume groups) at the secondary site can be recovered with full update sequence consistency, but the updates will be behind the primary site due to the asynchronous remote copy operations. URz provides update sequence consistency for user-dened journal groups (e.g., large databases) as well as protection for write-dependent applications in the event of a disaster.

Add Pair Operation

The Siz add pair operation establishes the new specied Siz pair(s). The volume which will be the S-VOL must be in the simplex state, and the volume which will be the T-VOL must be reserved (if assigned automatically) and simplex before being added to a Siz pair. The Add Pair Dialog box (see section Resetting the Reserve Attribute on page 73) allows you to add (start) new Siz volume pairs. The CESTPAIR and PPRCOPY ESTPAIR commands allow you to add (start) Siz pairs. SeeChapter 5 on page 99 for further information on PPRC commands.

Initial Copy Operation

Initial copy is a process where Siz copies data in an S-VOL to a T-VOL when you create a volume pair. The Siz initial copy operation takes place when you add a new Siz pair. The initial copy operation copies all data on the S-VOL to the associated T-VOL(s). The S-VOL remains available to all hosts for read and write I/Os throughout the initial copy operation. Figure 5 on page 26 shows the change of the status of a pair from the start to the end of the initial copy operation.

Figure 5 Adding a Pair Before the initial copy operation, the status of a pair is Simplex. The status of the pair is Pending while the initial copy operation is in progress. The status changes to Duplex when the initial copy is complete. Write operations performed on the S-VOL during the initial copy operation are duplicated at the T-VOL by update copy operations after the initial copy is complete. CAUTION: Even if the copy operation is completed without any host I/O, the data in the S-VOL and the data in the T-VOL may not be the same. Whether the S-VOL and the T-VOL have the same data depends on the condition of the storage system. To make the S-VOL data and the T-VOL data equal, split the pair and make the pair status split.
NOTE: When adding pairs, you can select the pace for the initial copy operations: slower, medium, or faster. The slower pace minimizes the impact of Siz operations on storage system I/O performance, while the faster pace completes the initial copy operations as quickly as possible.

Update Copy Operation

The Siz update copy operation updates the T-VOL of a Siz pair after the initial copy operation is complete. Since an S-VOL remains available to all hosts for read and write I/Os during the initial copy operation, the S-VOL might be updated during the operation. Therefore, when the status of the pair changes to Duplex after the initial copy operation is complete, the update copy operations take place and the differential data of the S-VOL is copied to the T-VOL. As write I/Os are performed on a duplex S-VOL, the storage system stores the differential bitmap, and then performs update copy operations periodically based on the amount of differential data present on the S-VOL as well as the elapsed time between update copy operations. Figure 6 on page 27 illustrates an update copy operation in a Siz pair with only one T-VOL.

When a split pair is re-synchronized in normal mode, only the S-VOL differential data is copied to the T-VOL. When a suspended pair is re-synchronized, the entire S-VOL is copied to the T-VOL. No update copy operations are performed during resync operation. When a split pair is reverse copy, the XP12000 storage system copies only the T-VOL differential data to the S-VOL. The reverse copy cannot be performed on suspended pairs. No update copy operations are performed during reverse copy or quick restore. The XP12000 storage system does not perform update copy operations to a suspended T-VOL. The XP12000 storage system marks the entire S-VOL track map as differential data, so the entire S-VOL is copied to the T-VOL when the pair is resumed. Use resync command to resume a suspended pair. Reverse copy and quick restore cannot be used to resume suspended pairs.

Cautions on Switching Off Power Supply
If you must switch off the power supply of the XP12000 storage system during Siz operations, make sure to: Complete copying for the Siz pair in the SP-pend or V-split status to change the pair status from SP-pend or V-split to split, and then switch off the power supply.
NOTE: If the shared memory is volatilized when you switch on the power supply again, the pair in the SP-pend or V-split status changes to suspend. Complete the processing of At-Time Split function, and then switch off the power supply. NOTE: If the status of only a part of the pairs in the same consistency group is changed, the processing of At-Time Split function may not resume when you switch on the power supply, and the status of some pairs may remain unchanged. Establish a timetable for Siz copying operations based on required copying time that may take longer because of the power-supply off (PSOFF). NOTE: If the shared memory is volatilized when you switch on the power supply again, the following conditions occur: If the Siz pair was in the pending or resync status, data that was already copied before the power-supply off (PSOFF) again becomes the target data to be copied after the power-supply on (PSON). Even if there is no host I/O, the data consistency rate does not reach 100% when the Siz pair status changes to duplex. When the Siz pair status changes to duplex, the target data is copied to the T-VOL. If the Siz pair was in the duplex status, data that was already copied before the power-supply off (PSOFF) again becomes the target data to be copied after the power-supply on (PSON). In this case, the data consistency rate is 0%, and the target data is copied to the T-VOL. If the Siz pair was in the split status, the entire volume becomes the differential data. In this case, the data consistency rate is 0%, and the entire volume is copied to the T-VOL when you perform the resync pair operation.

Figure 19 Siz and TCz: Shared S-VOL/M-VOL and S-VOL/R-VOL The following is an example of a volume functioning as both a Siz T-VOL and a TCz M-VOL.
Figure 20 Siz and TCz: Shared T-VOL/M-VOL This conguration does not allow Siz and TCz to copy at the same time. Add the Siz pair rst, and then split the pair before creating the TCz pair. You must suspend the TCz pair in order to resync the Siz pair. The TCz pair status cannot be changed when the Siz pair is in the V-Split status. When you use the Siz and TCz shared conguration, you must either use the PPRC command to perform the Steady Split operation, or use the Remote Web Console to conrm the pair statuses. You can perform the Steady Split operation by specifying the CSUSPEND parameters (Byte 7 = M, Byte 8 = P, Byte 9 = S). For more information about the PPRC commands, see Chapter 5 on page 99. Usually TCz and URz can share the volumes with Siz. However, in some cases, you cannot create Siz pairs using the volume shared with TCz and URz. NOTE: A primary volume (P-VOL) of URz means a primary data volume of URz. A secondary volume (S-VOL) of URz means a secondary data volume of URz. The following conguration shows an example of a volume functioning as both an URz S-VOL and a TCz M-VOL. In this conguration, you cannot use this volume as the S-VOL of a Siz pair.

Combining Hitachi ShadowImage for z/OS with Universal Replicator for z/OS
URz volumes can be assigned to Siz pairs, and Siz volumes can be assigned to URz pairs. NOTE: A primary volume (P-VOL) of URz means a primary data volume of URz. A secondary volume (S-VOL) of URz means a secondary data volume of URz. Siz and URz can function together in the same HP StorageWorks XP12000 storage system or XP10000 storage system to provide both internal and remote backup for your important data. To query the status of a Siz pair when Siz and URz pairs share the same volume, do the following: Query the Siz S-VOL and T VOL status from the host if the Siz S-VOL and URz P-VOL share the same volume. Query the Siz T VOL status from the host if the Siz S-VOL and URz S-VOL share the same volume. Query the Siz S-VOL status from the host if the Siz T-VOL and URz P-VOL share the same volume.
NOTE: Siz supports multiple T-VOLs for each S-VOL. If you issue a pair status query to an Siz S-VOL, the status for only one Siz pair is reported (the pair with the T-VOL with the lowest LDEV ID). To obtain the pair status for the Siz pair(s) with the other T-VOL(s), you must direct the host query to the specic T VOL using the T-VOLs LDEV ID in the host command. The Siz remote console software displays the LDEV ID and Siz pair status of all T VOLs associated with an S-VOL. When you perform PPRC command to the Siz/URz shared volumes to query the pair status, the storage system reports pair status of the Siz. To query pair status of the URz from the host, use XP for Business Continuity Manager Software.

This conguration allows you to: Use Siz to provide on-site backup copies of URz P-VOLs and S VOLs, and/or. Use URz to provide remote backup of Siz S-VOLs
Figure 25 Siz and URz: Shared S-VOL/P-VOL and S-VOL/S-VOL The conguration shown below is an example of a volume which is functioning as both a Siz T-VOL and a URz P-VOL. This conguration allows you to use URz to provide remote copies of Siz T-VOLs.
Figure 26 Siz and URz: Shared T-VOL/P-VOL NOTE: In the conguration shown, you cannot perform the Siz and URz copy operations at the same time. First you must create and split the Siz pair, then create the URz pair. If you want to re-synchronize the Siz pair, suspend the URz pair beforehand. You cannot change the URz pair status while the Siz pair is in V-Split status.
NOTE: Usually TCz and URz can share the volumes with Siz. However, in some cases, you cannot create Siz pairs using the volume shared with TCz and URz.
Starting up Hitachi ShadowImage for z/OS Feature
After you have completed the preparation to use the storage system and prepared for Siz operations, you are ready to start up the Siz feature: 1. Start up and log on to the Remote Web Console. 2. Start a Web browser on the Remote Web Console, and display the storage device list. 3. Log on to the SVP of the storage system on which you are performing Siz operations. The Remote Web Console main window opens (see section Hitachi ShadowImage for z/OS Main Window on page 61). 4. Click the Siz button on the Remote Web Console main window to open the Siz main window. The Siz main window displays the name of the connected storage system, the currently selected CU image, and all of the volumes (LDEVs) installed under the current CU image. You are now ready to perform Siz operations. First, reserve the volumes that you plan to use as Siz T-VOLs (see section Setting the Reserve Attribute on page 72 for instructions), and then start adding the Siz pairs (see section Resetting the Reserve Attribute on page 73 for instructions).

NOTE: Volumes specied as the T-VOL of a Siz pair are automatically reserved by the storage system. The Non-Pair check box allows you to display non-paired (simplex) volumes. The Pair Status box allows you to lter the pairs displayed in the Volume List box by pair status: Pending, Duplex, Split, Resync, Suspend, Resync-R, V-Split, SP Pend, Deleting, and F-Copy. NOTE: All check boxes are selected by default. The OK button applies the settings, and closes the Display Filter dialog box. The Cancel button resets the settings, and closes the Display Filter dialog box.
NOTE: The settings in the Display Filter dialog box are only effective within the current Siz operations. If you switch to another option program (e.g., TCz), or click a button on the toolbar on the Remote Web Console main window, the settings in the Display Filter are reset.

CAUTION: During the quick restore operation, the RAID levels, HDD types, and Cache Residency Manager for z/OS settings are swapped. To avoid impacting performance during quick restore operations:
a. Make sure that the S VOL and T VOL have the same RAID level and HDD type before performing the quick restore operation. If you want to restore the original RAID levels after quick restore, stop host I/Os to the pair, split the pair, perform the quick restore operation for that pair again, and then restart the host I/Os to the pair. b. Because the Cache Residency Manager for z/OS settings are exchanged during a quick restore operation, you must perform one of the two following operations. If you do not, the change of location of the cache residence areas may cause I/O performance to the Cache Residency Manager for z/OS data to be down: Set the same Cache Residency Manager for z/OS settings (locations) for the S VOL and T VOL before performing the quick restore operation. Release the Cache Residency Manager for z/OS settings of the S VOL and T VOL before the quick restore operation, and then reset the Cache Residency Manager for z/OS settings of the S VOL and T VOL after the pair changes to duplex status as a result of the quick restore operation. NOTE: If you do not want to re-synchronize the S-VOL and T-VOL after the quick restore operation, you must set the Swap & Freeze option before performing the quick restore operation (see sections Swap&Freeze Option on page 38 and Setting Hitachi ShadowImage for z/OS Options on page 93). 5. Click the OK button to reect the settings to the Preset List on the Siz main window. NOTE: If you try to perform the quick restore operation to the pair you selected from the Pairresync Volume List that is (composed of volumes stored in multiple cache logical partitions (CLPRs)), a message appears asking whether you want to continue the operation. Click the OK button if you do, or click the Cancel button if you want to discontinue the quick restore operation. 6. Repeat steps (4) through (5) until the Preset List on the Siz main window displays the desired pairs (settings). Make sure to set the T-VOL(s) ofine before starting resync operations. 7. On the Siz main window, click the Apply button to re-synchronize the specied pair(s). The Siz main window then displays the result(s) of the Resync Pair operation(s) (i.e., pair status changed to resync, resync-R, or duplex) and the progress (%) of the update copy operation. The pair status changes to duplex immediately, if the update copy operation is not necessary. 8. Click the Refresh button ( ) on the Remote Web Console main window to monitor the progress of the pair copy operation(s).

Data sheet

Maintaining control in a changing world
One thing remains constant in todays rapidly changing worldthe need to maintain control of important business information. HPs StorageWorks XP disk arrays are highly reliable and highly available enterprise class storage systems designed to provide control in the midst of change. And providing the means to meet changing storage demands head-on is HP StorageWorks LUN Configuration and Security Manager XP. It is the core software package that provides XP disk array volume management, security, and performance features. LUN Configuration and Security Manager combines configuration and security into a single integrated and flexible solution. Administrators can add and delete I/O paths, create custom-sized volumes and configure foolproof security to provide controlled access to data stored on the XP disk arraythereby preventing unauthorized access or modification. In addition, LUN Configuration and Security Manager for the XP12000 and XP10000 includes extra data protection in Oracle environments, and the ability to enhance performance for specific volumes by reserving portions of cache for frequently accessed data. Because it provides core functionality, LUN Configuration and Security Manager is a required purchase for XP disk arrays connected to open systems, and is an optional purchase for XP disk arrays connected to mainframes.

Features and Benefits

Simplicity and agility HP LUN Configuration and Security Manager XP provides easy-to-use menus permitting array group definition, logical volume creation, port configuration, and data access permission configurationall online, without downtime. HP LUN Configuration and Security Manager XP allows the administrator to combine two or more logical devices so that they function as one larger logical volume. This allows hosts that can only address a limited number of logical volumes to greatly expand the amount of data that can be accessed. HP LUN Configuration and Security Manager XP allows the administrator to configure custom volumes that are smaller than standard volumes. Custom volumes improve data-access performance by reducing the logical device contention that can occur when several frequently accessed files are located on the same volume. HP LUN Configuration and Security Manager XP is integrated into HP StorageWorks Command View XP Advanced Edition Software, and is easily accessible from the Command View XP AE management station. Open-system and mainframe capabilities are combined in a single convenient product.
