    Default How to dedicate one of my drives to NDMP backup?

    Hi,

    I have four LTO4 drives. Then I today backup my netapps with NDMP it often fails. This happends when the NDMP process fill up one tape and wants to change to another. Another job that been waiting then steals the drive and the NDMP process tries to get higher priority but always fails and the NDMP backup job gets canceled.

    How can I dedicate a drive to just my NDMP job?

    Hi,

    "update node XYZ keepmp=yes" is not enough?
    KEEPMP
    Specifies whether the client node keeps the mount point for the
    entire session. The parameter is optional. You can specify one of the
    following values:

    No
    Specifies that the client node release the mount point during the
    session. If policy definitions cause data to be stored to a disk
    storage pool after storing data to a sequential access storage
    pool, any mount points held by the session will be released.

    Yes
    Specifies that the client node must retain the mount point during
    the entire session. If policy definitions cause data to be stored
    to a disk storage pool after storing data to a sequential access
    storage pool, any mount points held by the session will not be
    released.
    If this does not help then you can define new library, take one drive from the original one (delete path, delete drive), define it in the new one, create dedicated management class and point your NDMP backups there .... Can be done but question is if it is worth the effort ...

    Hi,
    Have not tried the keepmp=yes option. Will try this when the node is idle before next try...
    Can not change now because the node is accessing the server at moment.
    Thanks!

    Hi again,

    I this morning updated my node with keepmp=yes but the problem occured even with this option set. I think I have to consider dedicate a drive...

    Thanks Harry.

    you can dedicate one drive to the netapp-datamover - if you define a path to the specific drive only

    hi!

    we are getting a NETAPP Filer next week.
    So i am looking for configuration hints.

    as i read this thread it is possible to:
    have 10 drive and use them in 2 devc. one for normal file backup and one for type netappdump!!

    but regarding the problems: would you recommend to do so?
    normally we have onle ONE devc for ONE logical library.

    is anyone using drives for FILE and NETAPPDUMP at the same time without problems?

    thanks!

    I have 7 drives, 4 are pathed to NAS and 3 pathed to TSM server. So NAS has 4 dedicated drives that are only used by NDMP.
    Normal TSM (non-NAS backups) go to the 3 drives pathed only to TSM server. By pathing you can dedicate your drives and they are not shared between NDMP and TSM server.
