To define or operate XP Continuous Access Synchronous pairs in TrueCopy Open/MF consistency
groups, install the XP Continuous Access Synchronous software. A TrueCopy Open/MF consistency
group and an XP Continuous Access synchronous consistency group described in the HP
StorageWorks XP24000/XP20000 Continuous Access Software User's Guide behave the same.
For more information about XP Continuous Access Synchronous consistency groups, see the HP
StorageWorks XP24000/XP20000 Continuous Access Software User's Guide.
You must use the same consistency group number when XP Continuous Access synchronous pairs
and TrueCopy for Mainframe synchronous pairs are registered in the same TrueCopy Open/MF
consistency group. Therefore, you must decide beforehand the consistency group number to be
used in RAID Manager and Business Continuity Manager. Specify an unused consistency group
number when creating a new TrueCopy Open/Mainframe consistency group. Before performing
any operations on the combined consistency group, define the pairs specifying the group number
in RAID Manager and in the Copy Group Attributes (TC) window of Business Continuity Manager.
For more information about the Copy Group Attributes (TC) window, see HP StorageWorks Business
Continuity Manager Software User Guide.
TrueCopy for Mainframe Async Consistency Group Operations
TrueCopy for Mainframe Async consistency groups enable update sequence consistency to be
maintained across a group of volumes. The R-VOLs of the pairs in a consistency group must be
located within one RCU (n-to-1 requirement). The TrueCopy for Mainframe Asynchronous consistency
group operations include:
•
“Group Options” (page 32)
•
“Group Consistency Time” (page 32) Group consistency time
•
“Group Operations” (page 33) Group operations
