HP StorageWorks XP Continuous Access User Guide: HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200 Storage Virtualization System (T1711-96025, May 2011)

NOTE: If an LDEV number contains # at the end (such as 00:3C#), the LDEV is an external
volume. For more information about external volumes, see the HP StorageWorks XP External
Storage Software user guide: HP XP12000 Disk Array, HP XP10000 Disk Array, HP 200
Storage Virtualization System.
NOTE: For P-VOL or S-VOL, the Port - G-ID - LUN part displays the port number, G-ID, and
LUN of the volume that you specified in the remote storage system when creating the pair. If
you change or delete the port number, G-ID, or LUN of the volume in the remote storage
system, incorrect information will be displayed in P-VOL or S-VOL. So, unless you have any
special circumstances, do not change or delete the port number, G-ID, or LUN that you specified
when creating the pair.
• CLPR: CLPR number and name of the volume on the primary site.
• Group Name:
Group name: Host group name if the port on the primary site connects a host group.◦
◦ iSCSI target: iSCSI target name if the port connects an iSCSI target. The iSCSI target
name is displayed up to 32 characters.
• Pair Status: SMPL, COPY, PAIR, PSUE, PSUS, PDUB, Suspending, or Deleting (see “XP
Continuous Access volume pair status” (page 23) for further information about XP Continuous
Access pair status). If the pair is split or suspended, the split/suspended type is also displayed.
• Pair Synchronized: How far the copy operation progressed in percentage and the progress
bar.
• RCU S/N and ID: Serial number and SSID of the RCU (or MCU if S-VOL is selected).
• MCU-RCU Path: Channel type of path interface between disk arrays (fibre or serial).
• Update Type: Synchronous or Asynchronous.
• Initial Copy Pace: 1-15 tracks (disabled when status is PAIR).
• Initial Copy Priority: 1-256 (disabled when the status is PAIR).
• P-VOL Fence Level: Conditions under which the MCU rejects write operations to the P-VOL.
Never: Never fence the operation◦
◦ Data: Fence when the MCU cannot successfully execute an update copy operation for
any reason
◦ Status: Fence only if the MCU cannot change the S-VOL status to the same status as the
P-VOL.
• S-VOL Write: Enabled or disabled for this pair (enabled only when pair is split).
• Pair Established: Date and time volume pair was created.
• Last Updated: Date and time volume pair status was last updated.
• Difference Management: Auto, Cylinder, or Track.
• Sync CT Group: Consistency group number for Synchronous-C pair.
• Asynchronous Parameter:
CT Group: Consistency group to which XP Continuous Access Async pair is assigned.◦
◦ Error Level: Error level for XP Continuous Access Async pairs.
