NDMP drive always goes down

mkc · ‎07-28-2008

We do weekly full backup on our filer, but we always get the error.

The drive was up, but it'll go down when tries to backup on NDMP.

I checked all the tpauotconfig, sysconfig, etc.. all showing correct status.

Logs as following;

Has this worked in the past, and has just stopped working? Or has it never worked?

Physically check the drive and ensure it is operational and there is no tape stuck in it.

What is the output for tpautoconf -probe <filername>? Ensure the path (that shows in the output) is correct when setting up the drive. Remember to stop ltid and restart it if you make any changes in tpconfig.

Hope this helps.

Hi run:

vmoprcmd -shmdrive | grep -i <drivename>

vmoprcmd -autoconfig -t

vmglob -listall -b | grep -i <drive serial number>

match the Drive Serial Number, Path and Name between this commands if there is a mistmatch you will need to update the drive info with tpconfig -update if everything is ok, check for drive errors, can be a dirty/bad drive.

It matches the serial. HP001 is the drive that's used directly for the NDMP through the fiber.

It works when I do the manual backup. The drive goes down when I do schedule backup. The drive seems to be down periodically by itself.

Hi mkc

HELP!

I am experiencing the same issue with our NetApp Filer drive (NDMP). It spontaneously will continue to do to DOWN status even when there are no backups scheduled. Did u find a fix for this issue? If so, I would really apprecaite it if you kindly share the resolution.

Thank you

Hi Karthikeyan,

Thank you for your response. I am not responsible for zoning our drives. Our Storage grp. does. Can you tell me exactly what you did to resolve this issue, by rechecking the zoning?

Thank you
