Multiple tapes being frozen, drives being down but Tape Library shows no hardware issues.
Hello, This problem seems getting serious. We have about 45 tapes in Quantum Scalar i3 with 4 drives and Netbackup 8.1 on RHEL 6.9. Once in a while, 1 or 2 of drives go down an tapes are marked frozen. I opened multiple tickets to Netbackup and Quantum, they really don't find the root cause of the problem, just recommend to upgrade firmware, unfreeze tapes, Up drives. That's all both tech supports do. Now I have nearly half of tapes got frozen and 2 drives down. Does anyone have experience on tackling down the similar issues, if then, please share your thoughts. Belows are the screenshots of Netbackup and Quantum Scalar i3 tape library.1.6KViews0likes4CommentsStorageTek SL500 Issues with the the drives
Hello Everyone, We have in the environment tape library SL500. We recently starting to face the error below whenever we try to load some media tapes and starting backup operations: Mar 12, 2019 4:11:29 PM - granted resource HP.ULTRIUM5-SCSI.004 Mar 12, 2019 4:11:29 PM - granted resource XXXXX-hcart2-robot-tld-0 Mar 12, 2019 4:11:29 PM - end writing Mar 12, 2019 4:11:29 PM - mounting BAR245 Mar 12, 2019 4:11:35 PM - current media BAR245 complete, requesting next media Any Mar 12, 2019 4:12:19 PM - current media -- complete, awaiting next media Any.

Mar 12, 2019 4:12:30 PM - Error bptm (pid=20049) error requesting media, TpErrno = Robot operation failed Mar 12, 2019 4:12:30 PM - Warning bptm (pid=20049) media id BAR245 load operation reported an error We contoacted Oracle support and they advised, after sharing a lot of logs, to replace the robot hand. We did it but the problem persists, then we jumped to the media tapes, removed all the old tapes and inserted new ones, and still on the same point and getting the same error. We tried to replace some drives, but no success noting that the drives are giving tape error whenever we load/unload media tapes. The Tape Drives by itlsef is HP LTO5 FC, and from the dump drive, it is showing that it is functioning well without error. But whenever we try to run a backup, the drive from the host goes down and give the error. Anyone faced this problem before?5.5KViews0likes10Comments
