Unable to reassign media owner from old NDMP host to new NDMP host

Hi,

Clustered Netbackup 7.5.0.7 running on Windows Server 2008 R2 Enterprise Master server

3 x Netbackup 7.5.0.7 running on Windows Server 2008 R2 Enterprise Media servers

3 x Netbackup 7.5.0.7 running on Windows Server 2008 R2 Standard Media servers

Old NDMP (NetAPP 3160 7-mode)

New NDMP (NetAPP 8060 C-mode)

StorageTek i500

HP LTO5 drives.

 

I have replaced an old NetAPP NDMP host with a new one, I am attempting to remove the old NDMP host paths but can't because there is still media owned by it.

I have carried out the change media owner, assigning the new NDMP host as the new owner but this fails as follows:

"Could not changed (sic) media owner: server name not found in the NetBackup configuration.

The host is not defined in EMM(254)"

I can assign the media to a media server but not an NDMP host, is this normal?

Thanks,

Alun.

    Look like that "bpmedia -movedb" command works for 1 media (-m) , but not for all (-allvolumes)..

    I would suggest doing it one by one and find out which media would fail, because doing -allvolumes  will not commit if one of the media fails.

    Add all media-id's in a text file and use as input to 'for' loop with -m option.

    What steps have you followed to add the new NDMP server? Have you tested it and make sure it works and can take backups? Do not try to change media ownership until backups are working fine.

    Hi Marianne,

    We have been backing up the new 8060s successfully since September, the old 3160s were subsequently removed and I was just trying to remove all of the "old" paths for each drive.

    I have 204 tapes to reassign but really wanted to assign them to the new NetAPP, that's where the error is generated.

    Old NDMP (NetAPP 3160 7-mode)

    New NDMP (NetAPP 8060 C-mode)

     

    Forget trying to reassign media.  You cannot restore 7-mode NDMP to Cluster Mode NDMP, only like kind. 

     

    * edit * sorry that is not correct

    In the GUI, select a tape, right-click and select Change Media Owner...

    Is your new NDMP device listed in the drop-down?

    Hi Will, That's what I tried to do, the NDMP is listed but reports the error when I click OK.

    Thanks, Alun.

    How about the output Mark suggested above?

    I've listed the results from the "nbemmcmd -listhosts -verbose" command, I've had to "generic" the names to protect our infrastructure but the affected new NDMP hosts are listed under NEWNETAPP1-01.

    Try to change media ownership via cmd: bpmedia -movedb -allvolumes -oldserver (oldserver ) -newserver ( newserver )

    Hi Marianne,

    That also returns "server name not found in the NetBackup configuration".

    I can obviously reassign the media to a media server but would rather reassign to the new NDMP host, I might have to raise a ticket???

    Thanks,

    Alun.
