Dynamic Provisioning workflow

The following diagram shows the workflow for setting up Dynamic Provisioning on the storage system.

Use Device Manager - Storage Navigator or RAID Manager to create pools and DP-VOLs.

CautionIf you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes must be formatted before use.
CautionIf the V-VOL data is migrated through the host, unallocated areas of the volume might 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 the 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 this procedure for each V-VOL.

  • Configuring thin provisioning

    Thin provisioning technology allows you to allocate virtual storage capacity based on anticipated future capacity needs, using virtual volumes instead of physical disks. Thin provisioning is an optional provisioning strategy for your storage systems. Thin provisioning is implemented by creating one or more Dynamic Provisioning pools (HDP pools) of physical storage space.
