Dear All ,
I am facing a problem with my netbackup setup for last couple of days . The setup is a tape library SL500 ( with four LTO4 drives ) and two media servers . Two drives are assigned to each media server. Every thing was working fine when suddenly in one of the media server , the drives went to go down after every backup is completed. Manually we have to up the drive and the next backup proceeds . The same thing repeats if this backup gets completed. We have already logged a case with our vendor SUN and Symantec , but doesn't seems that the problem can be resolved . As per the advice from symantec , the tape library firmware , the Fiber card firmware and the drives firmware were upgraded to latest one , but still the problem persist. Symantec is pressing that the drive is faulty and SUN is of the opinion that it is a bug in the software as they have already replaced both the drives.
The OS is solaris 10 with netbackup version 6.5.3.1 . Wherein the below messages gives the drive sense key as the media error , both the drives have been replaced but the problem is still the same.
Can anyone help pls to resolve the issue . The /var/adm/messages log is as given below :
