  • Page 6: Business Copy Z Overview

    1 Business Copy Z overview Unless otherwise specified, the term P9000 in this guide refers to the following disk array: P9500 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used. GUI contents also vary with licensed program products, storage system models, and firmware versions.

  • Page 7: Hardware And Software Components

    Hardware and software components A typical configuration consists of a P9500 storage system, a host connected to the storage system, Business Copy Z software, a source volume, a target volume or volumes, and interface tools for operating Business Copy Z. Interface tools include the Remote Web Console graphical user interface (GUI), Business Continuity Manager, IBM PPRC host software functions, or IBM DFSMSdss host software functions.

  • Page 8: Initial And Update Copy Operations

    Initial and update copy operations When you create a pair, the system executes an initial copy. When the pair is created, the storage system asynchronously copies updates received by the S-VOL to the T-VOL. Initial copy When you create a pair, the initial copy is started by the system, and all the data in the S-VOL is copied to the T-VOL.
  • Page 9 Figure 3 Update copy operation Although an initial copy completes and pair status changes to Duplex, the data in the S-VOL and T-VOL may not be the same because the copy of the update data is performed asynchronously. To ensure that S-VOL and T-VOL data are the same at a certain point in time, the pair must be split. CAUTION: 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.

RAID level RAID 1, RAID 5, RAID 6 Remote Web Console If you use Remote Web Console, it is necessary to be in Modify mode to perform pair operations.

  • Page 11: License Capacity Requirements

    Using the copy group, you can perform pair operations on all the pairs in the group at the same time, including the At-Time Split operation with which you can specify the split time. See the HP StorageWorks P9000 for Business Continuity Manager User Guide for information on setting up consistency groups and performing pair operations.

  • Page 12: Calculating Number Of Differential Tables, Pair Tables

    The number of differential and pair tables that are present in the system depends on additional shared memory that is installed. Therefore, you must insure that you have sufficient additional shared memory to handle the number of pairs. The following table shows the number of differential and pair tables and the number of volumes allowed per additional shared memory.

  • Page 24: Performing Configuration Operations

    4 Performing configuration operations This chapter provides configuration information and instructions. Configuration workflow Setup for Business Copy Z consists of the following: Ensuring that source and target volumes are set up correctly Reserving volumes for use as T-VOLs (optional) Setting the Host I/O Performance option, which boosts I/O performance, though copy time slows as a result (optional) Set up source and target volumes The source and target volumes must be set up prior to making copies.

    Ensure that the volumes you want to reserve are shown, and then click OK. The selected volumes display in the Preview List. When ready, on the Pair Operations window click Apply. To confirm the settings are applied, use the Display Filter dialog box. NOTE: LDEVs for S-VOLs and T-VOLs listed in Remote Web Console may end in the following special symbols:...

  • Page 28: Performing Pair Operations

    5 Performing pair operations This chapter provides instructions for performing pair operations using Remote Web Console. Pair operations workflow A typical operations workflow follows: Check pair status. Each operation requires a pair to have a specific status. You also check pair status to insure that an operation completed successfully.
  • Page 29 Because pair creation affects performance on the host, observe the following: Create a pair when I/O load is light. ◦ Limit the number of pairs that you create simultaneously. ◦ When a pair is created, both LDEVs are allocated to the processor blade to which the S-VOL was allocated before the pair was created.

  • Page 30: Split And Create Pairs

    NOTE: When the Preview List already holds some Add Pair operation settings and you specify a different copy pace for new pairs in the Add Pair dialog box, the copy pace for the existing Add Pair settings displayed in the Preview List will be also changed. The latest copy pace specified in the Add Pair dialog box is always reflected to the storage system.
  • Page 31 Triggers for change of pair status to Split What happens to pairs in V-Split or SP-Pend status depends on system option mode 459 (ON or OFF; OFF is the default) and whether the T-VOL (or the pool volume associated with the T-VOL) is an internal or external volume.
  • Page 32 In the Split Volume Pair dialog box, proceed as follows: Ensure that the pair you want to split is selected. Select the Simplex volume to be the S-VOL in a pair create and split operation. From Copy Pace, select the pace at which the pair(s) are to be split, Slower, Medium, or Faster. Copy Pace affects the host I/O performance: a slower pace minimizes impact, a faster pace has the greatest impact.

  • Page 33: Splitting Consistency Group Pairs With At-Time Split

    Before executing At-Time Split a second time, verify that status of all the pairs in the same consistency group is changed to the status which is specified by the YKEWAIT command. For detailed information about the YKEWAIT command, see the HP StorageWorks P9000 for Business Continuity Manager User Guide.

  • Page 34: Suspend Pair Creation

    Suspend pair creation When you suspend the creation of pairs (copy to the T-VOL of the pair), the pair status becomes Suspend. The T-VOL continues accepting write I/O operations to the S-VOL and marks the entire S-VOL track as difference data. When a pairresync operation is performed on a suspended pair, the pair status becomes Resync, and the entire S-VOL is copied to the T-VOL.

  • Page 35: Resynchronize Pairs

    Resynchronize pairs You resynchronize a pair that was split by a user or suspended by the system. Resynchronizing updates the T-VOL so that it is again paired with the S-VOL. CAUTION: Resynchronizing the pair does not guarantee that S-VOL data is the same as T-VOL data.
  • Page 36 With a Quick Restore, Remote Web Console may display outdated information. Click File/Refresh to insure the most up-to-date information. With a Quick Restore, to keep the S-VOL and T-VOL unsynchronized, enable the Swap&Freeze option before performing the Quick Restore. Update copy operations are then suppressed when the Quick Restore is completed and the pair is in Duplex status.
  • Page 37 In the Resynchronize Volume Pair dialog box, select the Resync Type as follows: CAUTION: Make sure to select the correct resync direction. Normal Copy(S->T) to resynchronize the pair(s) normally. All differential data is updated to the T-VOL. Quick Resync(S->T) to immediately change pair status to Duplex. Resynchronization of data does not occur immediately.

  • Page 38: Delete Pairs

    NOTE: Check the following: If the reverse copy or quick restore operation ends abnormally, the pair status changes to Suspend. In this case, the S-VOL is read/write-enabled for all hosts, but the data in the S-VOL is not guaranteed. The T-VOL remains write-disabled (read-only) and data is not guaranteed. The status of other Business Copy Z pairs sharing the same S-VOL does not change.

    6 Monitoring and maintaining the system This chapter provides information and instructions for monitoring and maintaining the Business Copy Z system. Monitoring the system Monitoring helps you keep track of pairs and volumes and their current and past conditions. Monitoring should be an ongoing activity. This section provides information for monitoring the following: Pair status.
