as per Marianne suggestion... logs are the next place to see

create bptm log dir

set verbose 5 

bring the tape dirve up

trigger the backup job again

let the job failed.

attached the bptm and failed job details status to this port.

 

if you would like you can also simple delete the drive from GUI and reconfigure it again and then test the backups.. if the backup failed.. collect the logs as per above and attach..

so are you taking the local NDMP backups.. where the Tape Drives are connected to filer?

if yes...

does filer able to see the tape Drives... if yes.. 

what is the output of below command 

tpautoconf -probe <filername>

tpautoconf -verify <filername>

does it displaying any Drives?

if filer is not able to see the tape Drives, you need to check with filer team to make sure filer is able to detect the tape drives before you start looking into netbackup level.

is the down drive... and it only one Drive configured for this filer..

0   COPDD2V1_PB_31       hcart3 TLD(14)  DRIVE=31
      /dev/rmt0.1                                                      UP
      nrst370h (datal5150)                                             DOWN

and it is also visible in probe command

  Device "nrst370h" attributes=(0x4) RAW
    DENSITY=LTO3 400GB
    ELECTRICAL_NAME=COPTAPA4801:338.56
    SERIAL_NUMBER=74900100F9
    WORLD_WIDE_NAME=WWN[2:000:002188:4c597c]
    ALIAS 0=st370

so no issues in connectivity end..

please proceed as below

vmoprcmd -reset 0

vmoprcmd -up 0

wait for 2-5 min make sure drive is up, if it is up, try the backups again and test it

if backups are running fine..you are good..

if the Drive does not come up, or went down again. remove the drive and reconfigure it and then test the backups.

Thanks a lot, I reset the drive and now it is in up state but it is not mounting the tape. would you suggest to removing and readding the drive will be the best at this point?

as it is not mounting the tape, and it was down previously i would suggest to check the hardware function..

try mounting  and dismounting the tape into Drive by using the robtest, and make sure it is successfull.. 

if you find any issues with Mounting, check if it has any stuck tape.. and raise a hardware call.

if you are able to do the mounding and dismounting without any issues...  go ahead and reconfigure it and see how it goes..

@Ram, We have tried mounting and dismounting a tape in the drive and it is working fine. can i have your next plan of action please?

 

@Marianne - Thanks for the information, are you suggesting me to get the bptm logs form master server or from file end please?

bptm log is on the 'NDMP media server'.

This is the media server you used to configure devices and Storage Unit for NDMP.

If you used the Master server, then you need to create bptm log folder on the master server.
