Specific database, log, file, and LUN settings are required
for IBM® System Storage®.
The
DS8000®,
SAN Volume Controller,
Storwize® V7000, and
XIV® storage
subsystems require these settings when you plan for
VSS backups:
- Place database files on a separate and dedicated logical volume.
- Place logs on a separate logical volume.
- When you use hardware snapshot providers, make sure the database
LUNs are dedicated to only one database or application.
- If you delete a LOCAL snapshot that is stored on a SAN Volume Controller or Storwize V7000 Space
Efficient volume (SEV) that has multiple dependent targets, you must
delete them in the same order in which you created them. You must
delete the oldest one first, followed by the second oldest, and so
on. Failure to delete them in this order can cause removal of other
snapshots of the same source.
- (SAN Volume Controller and Storwize V7000 only)
If you use multiple target FlashCopy® mappings,
a mapping can stay in the copying state after all the source data
is copied to the target. This situation can occur if mappings that
were started earlier and use the same source disk are not yet fully
copied. Because of this situation, initiate local backups for SAN Volume Controller and Storwize V7000 storage
subsystems at intervals greater than the time required for the background
copy process to complete.
