Storage pool management for NDMP operations

Edit online

When NETAPPDUMP, CELERRADUMP, or NDMPDUMP is designated as the storage-pool type, managing the storage pools that are produced by NDMP operations is different from managing storage pools that contain media for traditional IBM Storage Protect backups.

The following guidelines and restrictions apply to storage pools of the NETAPPDUMP, CELERRADUMP, and NDMPDUMP type that are produced by NDMP operations:
  • You can query and update storage pools, but you cannot update the DATAFORMAT parameter.
  • You cannot designate a CENTERA storage pool as a target pool for NDMP operations.
  • You can designate a directory-container storage pool as a target pool for NetApp NDMP operations.
  • When you protect data by using the PROTECT STGPOOL command, you can designate a directory-container storage pool as a target pool for NetApp NDMP data.
  • You can replicate NDMP data that is stored in a non-deduplicated, sequential-access storage pool.
  • You cannot replicate NDMP data that is stored in either a directory-container storage pool or in a deduplicated storage pool that uses the FILE device class.
  • You cannot use the cloud tiering process to move NDMP data from a directory-container storage pool to a cloud-container storage pool.
  • Maintaining separate storage pools for data from different NAS vendors is the preferred practice, even when the data format for both is NDMPDUMP.
  • The following DEFINE STGPOOL and UPDATE STGPOOL command parameters are ignored because storage pool hierarchies, reclamation, and migration are not supported for these storage pools:
    • MAXSIZE
    • NEXTSTGPOOL
    • LOWMIG
    • HIGHMIG
    • MIGDELAY
    • MIGCONTINUE
    • RECLAIMSTGPOOL
    • OVFLOCATION
Important: Ensure that you do not accidentally use storage pools that were defined for NDMP operations in traditional IBM Storage Protect operations. Be especially careful when you assign the storage pool name as the value for the DESTINATION parameter of the DEFINE COPYGROUP command. Unless the destination is a storage pool with the appropriate data format, the backup fails.
