I wanted to understand if the backups are getting hung because of tape drive issue or any other issue in my environment

we are using NBU 7.5.0.4 RHEL 

 

NetBackup-RedHat2.6.18 7.5.0.4

we are continously facing issues from our L1 team that the backups are getting hung however when i see them i dont see hung but they take longer time then normal I checked the os logs found some tape alert & bptm also shows that. i wanted to understand if the hung thing because of that tape drive or not

These errors should result in all sorts of device-related backup failures. Not hung backups.
What do you see in Job Details for jobs that match these timestamps?

Hi,

1) Have you checked how the status of the drives are in the IBM library console. Maybe there is some issues in the      drive or the tape.

2) And as Marrianne said, is it like only a few jobd are getting hung or is it like all tyhe jobs which are going to the tape drive are getting hung.

Regards,

Avinash
