Error nbjm (pid=5113) NBU status: 2009, EMM status: All compatible drive paths are down, but media is available

Hi

 

I have been trying to fix the below error for NDMP backups. Any help would be appreciated. The drive paths keeps going down.  No changes have been made recently. It was working fine before and suddenly giving lot of issues.

 

Here is the error.

Error nbjm (pid=5113) NBU status: 2009, EMM status: All compatible drive paths are down, but media is available
All compatible drive paths are down but media is available  (2009)
 

Thanks

Are the drives connected

Are the drives connected directly to your NDMP server or a media server?

Have you checked the system logs? If not, have a look and see what is reported at the time when the drive paths go down.

 

How many drives are affected?

Sounds like a direct drive

Sounds like a direct drive connection issue - though is does say that the drives are DOWN which indicates that they exist but are actually down

What can you see in Device Monitor for the drives? If any of then or their paths are in a down state then UP them

Yes the drives are connected

Yes the drives are connected directly to NDMP.

 

I checked the system logs and i see the following errors.

ioctl error on Drive4 (device 0, /dev/nst0) thru sg driver, Success
 

2 drives are affected and those are the 2 drives that's connected to that array.

The path keeps going down

The path keeps going down when it's in use. I tried bringing them up again but it does the same thing.

Check if tapes are not

Check if tapes are not stucked in tape drives ?

If these drives are in a

If these drives are in a library controlled by another host (media server) then run robtest from the media server to see if anything is in the drives - that should tell you also which slots they came from so that you can check if those slots are empty

I have seen a lot of drives stuck going down due to incorrect tape loading procedures if a slot gets filled that belongs to a tape in the drive

If you find that then move the tapes from the drives to a free slot and update the inventory in NetBackup after which you should be able to UP the drives

Also check the library web GUI (if it has one) to see if that is reporting anything.

I found out that the fibre

I found out that the fibre cable attached to tape drives was disconnected from switch, so we connected the cable again. We see the fibre logging in the switch. I rediscovered the tape drives on the server. Now I see the tape drives listed in the scan command output but I still see error in the gui. When I try to up the path, it says, unknown drive name. Any help would be appreciated.

Re-run the device wizard to

Re-run the device wizard to re-discover them correctly - if the fibres are now swapped around the paths will have changed

The device config wizard will update the paths

Also remeber to refresh the Admin Console and do the UP from the device monitor section and not in activity monitor

I re-ran the device wizard

I re-ran the device wizard and everything seems to be working right but one of the path is still down. I also rebooted the library.  I am getting below NDMP error when i try to run the NDMP backup.

Is anything getting logged on

Is anything getting logged on the filer - can it see the drives?

Not sure what filer you have but each one has various commands that can be run to scan its devices

We have EMC NS480 connected

We have EMC NS480 connected for NDMP backups. Can you let me know what are the commands to check in the filer.

See commands in EMC Cellera

See commands in EMC Cellera section of the NDMP Appliance Information

tpautoconf -verify celerra_host
to verify connectivity

To verify devices:
tpautoconf -probe celerra_host

 

Ask your NAS admin to check system logs for errors.
