Adding volumes to a 96-TB Media Server Deduplication Pool

When you configure a storage server for a 96-TB Media Server Deduplication Pool, you specify the pathname of the first storage volume. Before you can use the Media Server Deduplication Pool, you must add the other two volumes to the disk pool.

To add the other volumes to a 96-TB Media Server Deduplication Pool

  1. On the MSDP storage server, use the crcontrol utility to add the second and third 32-TB volumes to the disk pool. You must include the data directories as part of the pathname. The following is the command syntax:

    /usr/openv/pdde/pdcr/bin/crcontrol --dsaddpartition pathname

    The following two examples show how to add the pathnames for /msdp/vol1 and /msdp/vol2 volumes:

    # /usr/openv/pdde/pdcr/bin/crcontrol --dsaddpartition /msdp/vol1/data
    Partition /msdp/vol1/data was added successfully.
    
    # /usr/openv/pdde/pdcr/bin/crcontrol --dsaddpartition /msdp/vol2/data
    Partition /msdp/vol2/data was added successfully

    After the next polling cycle of the NetBackup Remote Manager and Monitor Service, the NetBackup Administration Console displays the new, expanded capacity for the disk pool.

    Note:

    For a Media Server Deduplication Pool, NetBackup exposes the storage as a single volume in the NetBackup Administration Console. Therefore, if you have a 96-TB Media Server Deduplication Pool, the number of volumes is 1 even though three volumes are used for the storage.

  2. On the MSDP storage server, you can use the crcontrol utility to verify that the Media Server Deduplication Pool contains the new volumes. If the volumes were added correctly, there should be three mount points as follows:
    /usr/openv/pdde/pdcr/bin/crcontrol --dsstat 2 | grep Mount
    
    Mount point count: 3
    =============== Mount point   1 ===============
    =============== Mount point   2 ===============
    =============== Mount point   3 ===============
  3. To display detailed information about the disk pool, use the crcontrol --dsstat 3 command, as follows:

    /usr/openv/pdde/pdcr/bin/crcontrol --dsstat 3
