Page 7: Business Copy Z Overview
1 Business Copy Z overview Abstract HP XP7 Business Copy Z, also known as Business Copy Z (or BC Z), uses local mirroring technology to create and maintain a full copy of a data volume within an HP XP7 Storage system.
Page 8: Business Continuity Manager
RWC communicates with the HP XP7 over defined TCP/IP connections. RWC is LAN-attached to HP XP7. For more information about using RWC, see the HP XP7 Remote Web Console User Guide. RAID Manager RAID Manager is a tool that uses the command line interface to run commands that perform most of the same tasks you can do with the RWC.
Page 9: Initial And Update Copy Operations
S-VOL. The data in the P-VOL is copied to the S-VOL. Initial copy workflow Initial copy is an operation that is performed by HP XP7 when you create a copy pair. Data on the P-VOL is copied to the S-VOL.
Page 10: Update Copy Workflow
P-VOL of a copy volume to the S-VOL. HP XP7 goes through the following process to create an update copy: HP XP7 marks I/O to the P-VOL in "DUPLEX" status as differential data and stores the location of the data in bitmaps for transfer to the S-VOL.

Required if you are running commands through an in-band fibre channel connection. Otherwise, RAID Manager is not required. For more information about RAID Manager and running commands through an in-band fibre channel connection, see the HP XP7 RAID Manager User Guide. Pair volumes The pair volumes.

“Workflow for determining the maximum number of BC Z pairs” (page 13). Consistency groups Maximum per HP XP7 storage system: 256 (including BC, BC Z, and Fast Snap (FS)) Note: You cannot place BC, BC Z, and FS pairs in the same CG. Maximum BC Z pairs per CG: 8,192 You can only use CGs reserved for BCM/IBM PPRC in BCM/IBM PPRC.
Page 13: Workflow For Determining The Maximum Number Of Bc Z Pairs
Auto LUN (using migration plans) Tables and installed shared memory The number of differential and pair tables that are present in the HP XP7 storage system depends on the amount of installed shared memory. Ensure that you have sufficient shared memory to handle the number of BC Z pairs you plan to create.
Page 14: Calculating The Number Of Tables If You Are Sharing Tables
S-VOLs than P-VOLs, then the number of allowed BC Z pairs decreases. Calculating the number of tables if you are sharing tables You can calculate the number of differential and pair tables your HP XP7 storage system needs to create BC Z pairs.

13). For example, if you plan to create 10 BC Z pairs of 3390-3 volumes and 20 BC Z pairs of 3390-L volumes in an HP XP7 storage system that has 26,176 differential tables, use the following calculation: (3 x 10) + (24 x 20) = 510, which is ≤ 26,176 If the emulation type is 3390-3, you will need three differential tables and one pair table.
Page 16: Guidelines For Maximizing Host I/O Performance
◦ BC Z can create high levels of internal activity in your HP XP7. Make sure the configuration is appropriate for the internal and host workload. Items that may help are additional parity groups, cache adapters, cache, DKAs, and MPBs.
Page 17: Workflow For Maximizing Quick Restore Performance
Use the following workflow to maximize the performance of restoring pairs using Quick Restore: Use the same RAID level and HDD device type for the P-VOL and S-VOL. For more information about HDD and HDD device types, see the HP XP7 Remote Web Console User Guide.
Page 18: Using Consistency Group Pair-Split With Shared Volumes
Using consistency group pair-split with shared volumes If you share BC Z P-VOLs in an HP XP7 storage system with Cnt Ac-S Z or Cnt Ac-J Z S-VOLs, you can use consistency group (CG) pair-split to keep BC Z S-VOLs consistent.
Page 19: Requirements, Restrictions, And Guidelines For Using Consistency Group Pair-Split With Shared Bc Z And Cnt Ac-S Z Or Cnt Ac-J Z Volumes
When you perform a CG pair-split on shared Cnt Ac-J Z P-VOLs, the following operations occur: Cnt Ac-J Z restores the journal data that was created before you restored the split time to Cnt Ac-J Z S-VOLs (BC Z P-VOLs). NOTE: If a BC Z pair is suspended due to a failure, the split time and the actual task start time must be the same in order to restore Cnt Ac-J Z journal data that you created before the...
Page 20: Supported Pair Statuses For Consistency Group Pair-Split
Requirements If you are sharing BC Z P-VOLs with Cnt Ac-S Z or Cnt Ac-J Z S-VOLs, CG pair-split has the following requirements: All pair operations must be performed using RAID Manager, BCM, or PPRC commands. The examples in this manual assume you are using BCM. You must share BC Z P-VOLs with the Cnt Ac-S Z or Cnt Ac-J Z S-VOLs.
Page 21 The following table shows when you can perform a CG pair-split, based on the BC Z pairs in the CG that are not paired (a status other than "DUPLEX"), and the resulting pair status after you perform the pair-split.

Page 34: Enabling System Options
NOTE: This processing-suppression/performance-improvement level requires more time to synchronize when you split a pair, which prolongs the time that the pair is in the process of being Quick Split ("V-Split/SUSPVS" status) or Steady Split ("SP-Pend/TRANS" status). If this is a problem, complete one of the following: –...

Page 36: Managing Business Copy Z Pairs
5 Managing Business Copy Z pairs Abstract This chapter provides instructions for completing BC Z pair user tasks using the RWC and information on ATTIME Suspend using BCM. Workflow for managing Business Copy Z pairs During most pair user tasks, the P-VOL remains available to the host for I/O operations. You must have the Storage Administrator (Local Copy) role to perform BC Z pair user tasks.
Page 37: Bc Z Pair Creation
BC Z pair creation When you create a pair, the HP XP7 storage system performs an initial copy to copy data in the P-VOL to the S-VOL. You can create the BC Z pair and immediately split the pair so that you can access the S-VOL.
Page 38: Prerequisites For Creating Bc Z Pairs
Creating a BC Z pair copies the P-VOL to the S-VOL. If your HP XP7 has encryption DKAs, you can copy an encrypted volume to an unencrypted volume. There is no guard logic to enforce copying encrypted P-VOLs to only encrypted S-VOLs. Unless there is a specific reason for the data to become unencrypted, make sure you maintain the encryption by using only encrypted S-VOLs.
Page 39 - Steady Split:Copies the differential data to the S-VOL, and then splits the new pair. Default: Quick Split For Copy Pace, select the rate at which you want the HP XP7 storage system to copy data. Values: - Slower: Improved host I/O performance but slower processing speed.
Page 40 In the Select Primary Volumes window of the Create BC Pairs wizard, complete the following: In the Available LDEVstable, select the LDEV you want to be the P-VOL, and then click Add. NOTE: You can make multiple selections. The LDEV is moved to the Selected LDEVs table. Click Next.
Page 41 In the Select Secondary Volumes window of the Create BC Pairswizard, assign LDEVs as S-VOL to the specified P-VOL LDEV (or LDEVs). Complete the following, and then click Finish: If you specified one P-VOL, select a secondary LDEV from the Available LDEVs table, and click Set.

Page 43 For Number of Secondary Volumes, select the number according to the pair with the highest number of S-VOLs, even when some pairs do not have many S-VOLs. For more information about creating pairs, see “Creating BC Z pairs” (page 38). Remove the unwanted volumes.
Page 44 Use the following workflow to create the two pairs in this example: Open the Select Pair Configuration window of the Create Pairs wizard. For Number of Secondary Volumes, select 2, and then click Next. The storage system operates on the assumption that you are creating two pairs, each having two S-VOLs.
Page 45: Suspending Bc Z Pair Creation
I/O operations from the hosts, and host data written to the P-VOL after the suspend is issued will be marked as differential data. The HP XP7 storage system automatically suspends a pair in the following cases: An error condition related to an update copy operation is detected.
Page 46 In the RWC main window, in the resource tree, click Replications > Local Replication > BC Pairs. In the BC Pairs tab, select the pair that you do not want to create and click More Actions > Suspend Pairs.

For more information about the registering split times, see the HP XP7 Business Continuity Manager User Guide. BC Z pair resynchronization You can resynchronize split ("Split/SUSPOP" status) or suspended ("Suspend/SUSPER" status) pairs. Resynchronization causes the split volume pairs to become DUPLEX. Resynchronizing a split pair copies the P-VOL's differential data to the S-VOL and again pairs the S-VOL with the P-VOL.
