Figure 4 XP Snapshot pair status transition
1. If a volume is not assigned to a XP Snapshot pair, its status is SMPL.
2. Issue the paircreate command on the SMPL volume to create a XP Snapshot pair. When creating
the first pair for the P-VOL, the pair status changes to COPY. When the operation completes, the
pair status changes to PAIR.
If you specify a volume that is already paired with one or more S-VOLs as the P-VOL to create
another pair, the pair status does not change to COPY. When the operation completes, the pair
status changes to PAIR.
NOTE:
• If you execute the paircreate command immediately after deleting the P-VOL's last
snapshot data, it might take time to create a new pair.
• If the pool capacity exceeds the threshold when a XP Snapshot pair is in PAIR status,
the pair status changes to PFUL in XP RAID Manager. For more information, see the HP
StorageWorks XP RAID Manager user guide .
• If you issue the paircreate command when the pool capacity exceeds the threshold, the
command is rejected and you cannot create the pair.
