Creating XP Snapshot Pairs
Use the paircreate command of the RAID Manager to create XP Snapshot pairs. To create XP
Snapshot pairs, the following are required.
•
Specify a volume that meets the requirements in “P-VOL Requirements” (page 33) as a P-VOL
•
Specify a volume that meets the requirements in “S-VOL Requirements” (page 34) as an S-VOL
•
Specify the same size volumes as a P-VOL and S-VOL
•
When you use a volume that is already used as the P-VOL of another pair for the P-VOL of
the new pair, specify the same pool for the pairs which share the P-VOL
For details about the paircreate command, see the HP StorageWorks XP RAID Manager User
Guide.
Storing XP Snapshot Data
Use the pairsplit command of the RAID Manager to store snapshot data in the pool. You can
store 64 snapshot data at most per P-VOL. To store snapshot data, the pair status must be PAIR.
When a P-VOL is paired with two or more volumes, make sure that none of the pairs is in
COPY(RS-R) status. If some pairs are in the COPY(RS-R) status, the pairsplit command may end
abnormally.
During execution of the pairsplit command to the XP Snapshot pair, do not execute the
pairresync -restore
command to the other XP Snapshot pair that shares P-VOL with the
corresponding pair. The pairsplit command being executed may end abnormally. Possible
causes are as follows:
•
Command rejection
•
Timeout (Error code: EX_EWSTOT)
•
Suspending the pair (Error code: EX_EWSUSE)
