Thin Provisioning workflow
The following diagram shows the steps for a Storage Administrator to follow in setting up Thin
Provisioning on a storage system.
Use Remote Web Console or RAID Manager to create pools and THP V-VOLs.
CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes should
be formatted before use.
CAUTION: If the V-VOL data is migrated through the host, unallocated areas of the volume may
be copied as well. The used capacity of the pool increases after the data migration because the
areas that were unallocated before the data migration have become allocated areas due to
migration.
To migrate the V-VOL data:
1.
Copy all data of V-VOLs from the source to the target.
2. Perform the operation to reclaim zero pages.
Perform this procedure for each V-VOL. When data migration is done on a file-by-file basis, perform
the operation to reclaim zero pages if necessary.
To restore the backup data:
1.
Restore the V-VOL data.
2. Perform the operation to reclaim zero pages.
Perform the above procedure for each V-VOL.
