what is a "disk pool name"?

i'm going over the article on this link http://sysarticles.com/how-to-find-orphaned-images-on-disk-for-netbackup-dedup-disk-or-advanced-disk-full-problem/#comment-3248 to find orphaned images. it mentions of a "disk pool name" to start with.

what is a "disk pool name" and how to find it?

  • From under - “Media and Device Management” -> “Devices” -> “Disk Pools" in the GUI you can see the names.

    Or to use nbdevquery -listdp -l (this is outlined in the doc you mention.

     

    As to what is a diskpool - well it's the name given to a pool of disks :)

  • Hi rino19ny,

    (From NBU AdvanceDisk Storage Admin Guide) A Disk Pool represents disk volumes on the underlying disk storage. NetBackup aggregates the disk volumes into pools of storage you can use for backups. A disk pool is the storage destination of a Netbackup storage unit.

    A Disk Pool Name is the assigned name of the disk pool for the volume.

    As per Deb Wilmont, you can verify disk pool names in two ways. First is by going through the GUI or by command line.

     

    Command Line:

    (For Windows)

    <Install_path>\NetBackup\bin\admincmd\nbdevquery -listdp -l

     

    (For UNIX)

    /usr/openv/netbackup/bin/admincmd/nbdevquery -listdp -l

     

  • Maybe best to tell us about your environment and why you believe that you may have 'orphaned images'?

    The article that you have found clearly mentions  DEDUP DISK OR ADVANCED DISK  in the topic.

    Do you have Dedupe or Advanced disk in your environment?

  • the NBU environment was turned over (more like dropped on my lap) so i'm still learning the ropes.

    i don't know how to answer you but i do know right after a disk backup, it gets dedup to tapes. i also know that images stay for at least a week on disk before expiring.

    what i'm after is, if the images expire after a week, what's taking up space in my "disk pools"? isn't it that when a policy mentions expire after a year, that refers to the backup on tape? and not on disk?
