CAUTION:
If a failure occurs during the restoration, the pair status changes to PSUE. To recover the PSUE pair,
delete the pair's snapshot data. When you recover the PSUE pair by deleting its snapshot data, the
P-VOL's data is not guaranteed. Therefore, you must overwrite the P-VOL with backup data or format
the P-VOL.
NOTE:
XP Snapshot does not support Quick Restore mode. Therefore, even if you specify Quick Restore
mode, Quick Restore mode does not take effect.
Deleting snapshot data
Use the XP RAID Manager pairresync command to delete snapshot data. You can store up to 64
snapshot data per P-VOL. Therefore, to store new snapshot data for a P-VOL that already has 64
snapshot data, you must delete old snapshot data.
If you delete snapshot data, free area in the pool increases. To delete snapshot data, issue the
pairresync command on XP Snapshot pairs in PSUS status. If the snapshot data shares a data area
with another snapshot data, only the snapshot ID is deleted; the data itself is not deleted from the
pool.
For more information about the pairresync command, see the HP StorageWorks XP RAID Manager
user guide.
NOTE:
XP Snapshot does not support Quick Resync mode. Therefore, even if you specify Quick Resync mode,
Quick Resync mode does not take effect.
Deleting XP Snapshot pairs
Use the XP RAID Manager command or Pairsplit-S pane to delete XP Snapshot pairs.
If you use XP RAID Manager to delete XP Snapshot pairs, you must use the pairsplit -S command. By
using this command, you can delete only one pair at a time. For more information about the pairsplit
-S command, see the HP StorageWorks XP RAID Manager user guide.
If you use the Pairsplit-S pane, you can delete multiple pairs at one time. You can open the Pairsplit-S
pane either from the XP Business Copy main pane or the XP Snapshot pane. To select pairs to be
deleted by port, host group, iSCSI target, or LUN, open the Pairsplit-S pane from the XP Business
Copy main pane. To select pairs by pool, open the Pairsplit-S pane from the XP Snapshot pane.
