    hi,

    please check if there is a stuck tape in tape Drive, without having info in netbackup?

    and also make sure if you robtest is able to mount and dismount the tapes without any issues?

    Hi Nagalla,
     
    The drives that the backup is using are virtual tape drives from our VTL, which are empty. I am also able to mount and dismount the tapes without any issues.
    Another strange issue we have is that the drives often go offline, without reason.
    This case only happen on NDMP backups, all other backups works fine.
     
    Thank you for your attention.
    Best regards

    hi,

    see you are finding anyting under the below path in NDMP host media server

    /usr/openv/netbackup/db/media/tpreq

    /usr/openv/netbackup/db/media/drives

    if you find, delete those entires,and restart the netbackup and check how it works,

    if it does not,

    remove all NDMP Drives from the Netbackup, and configure them again.

    I have to wait for some important jobs to finish, in order to do a safety restart to netbackup.
    Tomorrow I'll give new updates for this case.

    Thank you for your attention.

    Hi,
    sorry but couldn't get an answer until today.

    I did what you said above but unfortunately I still have the same error and same logs on NDMP backup.

    Do you have more ideas/suggestions?

    Best regards

    There seems to be some communication issues here too - mention of unexpected message from NDMP and a lot of name resolution going on - which seems to resolve host hames as IP addresses rather than names.

    Worth making sure you Master and Media Servers can reolve each other and the filer by short and FQDN name - use hosts files if neccesary.

    Odd to have robot / tape errors on a VTL so most likely a communications / configuration issue.

    Run through you config again and to be sure of everything and ask the NDMP admin for the messages log from the filer to see if that is showing any errors - also make sure that the fibre switches involved are not showing any issues (some switches will cause a port reset if any error is detected which can disconect drives)

    Finally take a look at the event log on the VTL to see if that is reporting anything

    This may all be a communications or connection issue, but if it centres around the NDMP then that is where you need to look

    Hope this helps

    In which NDMP method you have configured the backups? Local or remote or 3-way ? and is that VTL or PTL where the backup going?

    What do you mean by local or remote or 3-way? I only know that it supports:

    Host supports LOCAL backup/restore
    Host supports 3-way backup/restore

    Yes, the backup is going to VTL.

     

    We are investigating with the NetApp admin what Mark_Solutions suggest.
