Figure 26 Asynchronous Operation pane
The Asynchronous Operation pane contains the following items:
• Consistency Group tree: All consistency groups (default), only consistency groups already in use
(Used), or consistency groups available for use (Not Used).
• Consistency Group list: Consists of the following items:
• CTG: Consistency group number.
• This CU: CU that initially registered the consistency group. When the consistency group is not
registered, the column is blank.
• MCU: The local CU registered the consistency group.
• RCU: The consistency group is registered from the paired CU (the local CU is RCU).
• M&R: MCU and RCU are in the same disk array.
• M-R Path: Fibre Channel or serial. When the consistency group is not registered, the column is
blank.
• Offloading Timer: Maximum time between Continuous Access XP Async recordset transfers. If the
consistency group is not in use, this column is blank. If the CU is an RCU, this parameter is invalid,
and a hyphen appears in this column.
• Inflow Control: Indicates if inflow control is enabled. If the consistency group is not in use, this
column is blank. If the CU is an RCU, this parameter is invalid, and a hyphen appears in this
column.
• Paired S/N: Serial number of the paired disk array (disk array with the lowest serial number). When
the consistency group is not registered, the column is blank.
• Paired ID: SSID (Storage disk array ID) of the paired disk array (disk array with lowest SSID). When
the consistency group is not registered, the column is blank.
• Other S/N: Exist: Indicates that there is an RCU other than the one with the lowest serial number.
When there is no other RCU, the column is blank.
• CLPR: Number and name of the CLPR to which the volumes forming the pair belong. If the
consistency group is not in use, this column is blank. For more information about CLPRs, see the
HP StorageWorks XP Disk/Cache Partition User Guide.
• Operation: Current operation performed by the Asynchronous Operation tab.
