Adding volumes to a 250-TB Media Server Deduplication Pool
When you configure a storage server for a 250-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.
See About provisioning the storage for MSDP.
To add the other volumes to a 250 TB Media Server Deduplication Pool
- 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
datadirectories 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/vol1and/msdp/vol2volumes:# /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 250-TB Media Server Deduplication Pool, the number of volumes is 1 even though three volumes are used for the storage.
- 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 ===============
- To display detailed information about the disk pool, use the crcontrol --dsstat 3 command, as follows:
/usr/openv/pdde/pdcr/bin/crcontrol --dsstat 3
