HP StorageWorks XP Remote Web Console Software - Manual (Page 52)

• Before creating a pool, it is required that the virtual volume management area is created in
the shared memory. The virtual volume management area is automatically created when the
additional shared memory is installed. For details on installing additional shared memory, call
HP technical support.
• If any pools or XP Snapshot pairs are already created for testing purposes
before you actually start using XP Snapshot for production purposes, HP recom­
mends that you initialize the V-VOL management beforehand. For details, see
“ Initializing V-VOL Management Area or Pool Management Block ” on page 57.
You do not always need to delete the XP Snapshot pairs after storing snapshot data in the pool. However,
since one P-VOL can be paired with up to 64 S-VOLs, you need to delete the snapshot data or the
pairs that are not necessary. When you delete an XP Snapshot pair, the snapshot data of the pair will
also be deleted from the pool.
If a failure occurred and you restore an XP Snapshot pair, its snapshot data is written back to the P-VOL.
You may not be able to restore the pair if another pair is being restored.
For details about the status of the XP Snapshot pair and the operations on the pair, see
“ Status of the XP Snapshot Pairs ” on page 15.
