Restoring Snap

shot XP pairs

Use the RAID Manager XP pairresync -restore command to restore Snapshot XP pairs. The Snapshot XP

pair must be in PSUS status when you restore the pair.

When the restor

ation is complete, the pair status changes to PAIR. For m ore information about the

pairresync -restore comm a nd, see the HP StorageWorks RAID M anag er XP user guide.

CAUTION:

If a failure occurs during the restoration, the pair status changes to PSUE. To recover the PSUE pair, delete

the pair's sna

pshot data. When you r ecover the PSUE pair by deleting its snapshot data, the P-VOL's

data is not gua

r anteed. Therefore, you must overwrite the P-VOL with backup data or format the P-VOL.

NOTE:

Snapshot XP does not support Quick Restore mode. If you specify Quick Restore mod e, the Snapshot X P

pair is not restored even if the command ends normally.

Deleting sna

pshot data

Use the R AID Manager XP pairresync command to delete snapshot data. You can store up to 64

snapshot data per P-VOL. Therefore, to store n ew snapshot data for a P-VOL that alre ady has 64 snapshot

data, you must delete old s naps hot data.

If you delet

e 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 d ata area with another

snapshot data, only the snapshot ID is deleted; the data itself is not deleted from the po ol.

For more inf

ormation about the pairresync command, see the HP StorageWorks RAID Manager XP

user guide.

NOTE:

Snapshot X P does not support Q uick Resync mode. If you specify Quick Resync mode, snapshot data is

not delete

d even if the command ends normally.

Deleting Snapshot XP pairs

Use the RAID M anager XP c ommand or Pairsplit-S pane to delete Snapshot XP pairs.

If you use R AID Mana ger 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 HPStorageWorksRAIDManagerXPuserguide.

If you use the Pairsplit-S pane, you can delete multiple pairs at o ne time. You can o pen the Pairsplit-S

pane either from the Business Copy XP main pane or the Snapshot XP pane. To select pairs to be deleted

by por t, host group, iSCSI target, or LU N, 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.
