on sacning drives error “Specific device or network is no longer available”

Created: 23 Jun 2012 | 6 comments

I am facing and issue on my wintel media server as “Specific device or network is no longer available” while scanning the drives, as I check in NBU GUI jobs were stuck on mounting.

Master server is AIX

Media server is Wintel

What is NBU version on Master and Media server?

Which Windows version on Media server?

Have you verified comms between master and media server?

Have you verified that devices are visible at OS level on media server?

Any errors in Event Viewer Application or System logs?

Please also post output of the following:

On master:
/usr/openv/netbackup/bin/admincmd/nbemmcmd -listhosts -verbose

From cmd on media server:
<install-path>\veritas\volmgr\bin\scan

What is NBU version on Master and Media server?

Master is AIX 6
Media server wintel 2003

Have you verified comms between master and media server?

yes verified by ping from mater to media and media to master

Have you verified that devices are visible at OS level on media server?
There is some issue as it shows only 30 drives out of 90 drives through device config wizard and through sacn

I can see that you have quite a big installation with lots of media servers. I was hoping that you would indicate WHICH one is the problematic one?

PBX level comms with all media servers seem to be fine. Status for all seem  fine except for this one:

kgwkgpinnbu07r
        ClusterName = ""
        MachineName = "hkgwkgpinnbu07r"
        FQName = "hkgwkgpinnbu07r"
        LocalDriveSeed = ""
        MachineDescription = ""
        MachineFlags = 0xb7
        MachineNbuType = media (1)
        MachineState = not active for disk jobs (8)
        MasterServerName = "PG990SV"
        NetBackupVersion = 6.5.6.0 (656000)
        OperatingSystem = windows (11)
        ScanAbility = 5

If this is the one - please verify active/valid license keys. Check/verify that all NBU services are running.

You mentioned 90 tape drives! Is this a mix of physical and virtual drives?
If VTL drives - it is recommended to assign dedicated drives to each media server and only share physical drives.
I have never seen any media server being able to handle 90 tape drives!

If media server could previously see more tape drives there should be something in Event Viewer...

Last thought - check that Removable Storage Manager service is stopped and disabled on W2003 media server.

Hi Marianne,

Firstly sorry for late reply.

The issue was resolved the server kgwkgpinnbu07r abruptly rebooted so the services went down and was unable to estiblish connection we asked the OS team and was confirmed of its reboot as of CPU utilization went high.Asked them to check the services and if not start them .

As of nw every thing is fine.

Thanks for your valuable help.

So, problem was at OS level, right?
