HP StorageWorks XP Remote Web Console Software - Manual (Page 67)

Figure 13 Using XP Snapshot
To create the pools and V-VOLs, you need to use Remote Web Console. To create XP Snapshot
pairs and perform subsequent operations, you need to use the RAID Manager. When deleting
pairs, you can also use Remote Web Console.
•
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 recommends that you optimize the V-VOL
management beforehand.
You do not always need to delete the XP Snapshot pairs after storing snapshot data in the pool.
However, because 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.
Configuring the Volume List
You can display only the specified volumes in the volume list if you specify the conditions in the
Display Filter dialog box.
To display the Display Filter dialog box:
1. Display XP Business Copy's Pair Operation window.
