Deleting XP Snapshot Data
Use the pairresync command of the RAID Manager to delete snapshot data. You can store up
to 64 snapshot data per P-VOL. Therefore, to store the new snapshot data in a P-VOL that already
has 64 snapshot data, you need to delete the old snapshot data.
If you delete snapshot data, free area in the pool will increase. To increase the free area in the
pool, delete snapshot data by issuing the pairresync command on the XP Snapshot pairs in
PSUS status. However, if the snapshot data you try to delete shares a data area with other snapshot
data, only the snapshot ID will be deleted and the data itself will not be deleted from the pool.
For details about the pairresync command, see the HP XP RAID Manager User Guide.
XP Snapshot does not support Quick Resync mode. If you specify Quick Resync mode, snapshot
data will not be deleted even if the command ends normally. Therefore, even if you specify Quick
Resync mode, Quick Resync mode does not take effect.
Deleting XP Snapshot Pairs
Use the command of the RAID Manager or the Pairsplit-S dialog box to delete XP Snapshot pairs.
If you use the RAID Manager to delete XP Snapshot pairs, you need to use the pairsplit -S
command. By using this command, you can delete only one pair at a time. For details about the
pairsplit -S
command, see the HP XP RAID Manager User Guide.
If you use the Pairsplit-S dialog box, you can delete multiple pairs at the same time. You can open
the Pairsplit-S dialog box either from XP Business Copy's Pair Operation window or the XP Snapshot
window. To select the pairs to be deleted by the port or host group, open the Pairsplit-S dialog
box from the Pair Operation window. To select the pairs by pool, open the Pairsplit-S dialog box
from the XP Snapshot window.
Deleting XP Snapshot Pairs by Selecting the Pairs per Port
To delete XP Snapshot pairs by selecting the pairs per port:
1.
Change the mode of the Remote Web Console to Modify. If the mode is already changed to
Modify, you can skip this step. For information on how to change the mode, see the HP
XP24000/XP20000 Remote Web Console User Guide.
2. Display the Pair Operation window.
3. In the tree, select the port or host group that contains the XP Snapshot pairs you want to delete.
The list of the pairs or volumes is displayed in the volume list.
4. Select and right-click the XP Snapshot pairs you want to delete. A menu is displayed.
You cannot delete an XP Business Copy pair and an XP Snapshot pair at the same time.
5. Select the Pairsplit-S command from the menu. The Pairsplit-S dialog box ( Page 86 ) is
displayed.
6. Click OK. The Pairsplit-S dialog box closes and a list of the XP Snapshot pairs that you are
going to delete is displayed in the Preview list of the Pair Operation window.
7. Click Apply. The confirmation message indicating if it is OK to apply the setting to the storage
system is displayed.
8. Click OK. The confirmation message closes and the deletion of the pair is applied to the
storage system.
