Figure 51 Pairresync Dialog Box for Synchronous and Asynchrono us
The pairresync options are:
• P-VOL: Port - GID - LUN of the selected volume.
Note: If # is added to the end of an LDEV number
(for example, 00:00:3C#), the LDEV is an external volume. For details on external volumes, see
the HP
StorageWorks XP24000 External Storage Software User’s Guide.
• P-VOL Fence Level (Sync only): If desired, you can change the fence level of the pair(s). See
“Pair Options” on page 1 10 for further information on the fence level pair option.
•
Initial Copy Parameters (see “ Initial Copy Options” on page 109 for further information on
these options):
• Copy Pace (from 1 to 15): Select the number of the tracks 1-15 for the resync operation(s)
(default = 15).
• Priority (from 1 to 256): Set the desired priority (1-256) (scheduling order) for the resync
operations (default = 32).
• Asynchronous Parameters (Async only):
• Resume Range (default = Group):
Group: All pairs in the same consistency group(s) as the selected pair(s) will be
resynchronized. You must select only one pair in each consistency group. (For the former
version of Continuous Access, you could only resynchronize pairs in one group at a time.)
LU: Only the selected Continuous Access Asynchronous pair(s) will be resynchronized.
Note:
For the LU resynchronize range set ting, if you select pairs with PAI R status and other than
PAIR status in the same consistency group, unexpected suspend may occur during the pair
operations (Pairsplit-r, Pairsplit-S, and Pairresync) under heavy I/O load conditions. You can
