XP Snapshot Operations
Figure 18 on page 41 shows the use of an external volume for the XP Snapshot operation. In
Figure 18 on page 41, the mapped external volume is set as a pool-VOL of the XP Snapshot pair. For
details on XP Snapshot, see the HP StorageWorks XP24000 Snapshot User’s Guide.
The procedure for the operation is described as follows:
1. Use External Storage to map a volume in the external storage system as an internal volume
of the local storage system.
Caution: Set the emulation type of the volume to OPEN-V when you map the volume, because
the volume with the OPEN-V emulation type can only be set as a pool-VOL of XP Snapshot.
For details on the mapping operation, see
“ Mapping an External Volume Automatically ” on page 69.
2. The status of the mapped volume automatically becomes Normal. However, the volume
formatting processing is not executed automatically. If you need to format the mapped volume,
format the volume using the VLL function. For the volume formatting operation procedure, see the
HP StorageWorks XP24000 Virtual LVI/LUN (VLL) and Volume Shredder User’s Guide.
3. Create a pool and add the mapped external volume to that pool as a pool-VOL.
4. Set the P-VOL and S-VOL of the XP Snapshot pair with specifying the pool you have created
at step 3.
