56 Snapshot XP operations
Deleting snapshot data
Use the RAID Manager XP
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 Snapshot XP 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 RAID Manager XP
user guide.
NOTE: Snapshot XP does not support Quick Resync mode. If you specify Quick Resync mode, snapshot
data is not deleted even if the command ends normally.
Deleting Snapshot XP pairs
Use the RAID Manager XP command or Pairsplit-S pane to delete Snapshot XP pairs.
If you use RAID Manager XP to delete Snapshot XP 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 RAID Manager XP 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 Business Copy XP main pane or the Snapshot XP pane. To select pairs to be deleted
by port, host group, iSCSI target, or LUN, open the Pairsplit-S pane from the Business Copy XP main
pane. To select pairs by pool, open the Pairsplit-S pane from the Snapshot XP pane.
