  • We are trying to get DPM to release some disk space from the 18 TB so we can use it for other applications.  Right now DPM is only using 4 TB and has 8 TB allocated but we cannot use the remainder.

    Hi Andrew,

    Is your virtual disk on a SAN? If so can you re-architect your storage and carve up 8TB for DPM? Remember you don't want to present the entire 18TB to the DPM server as a disk and add this into the storage pool. DPM will use the entire disk. You want to only present an 8TB volume to DPM.

    Now being that DPM is already using the 18TB this may present a problem because you will need to do something with the protected data as you redo your storage.

    Hi Andrew,

    If I am understanding your question right you will need to remove a disk from the storage pool.

  • Unfortunately we only have 1 virtual disk.

    Hi Andrew,

    You would need to carve up the storage into smaller volumes and bring that into the DPM storage pool.

    I do not know the background to your storage but this is essentially what you would need to do.
