Frozen

2 Topics

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.

Hi Guys, i have a problem that i can't solved. i have 2 type robot machine, LTO 4 and LTO 5, but last month, my LTO 4 was failure and cannot be used anymore. so the company decided to use only LTO5 robot for any backup to tape. i have read that LTO 4 can be used for read and write in LTO5 machine, so i try to do backup my file to tape LTO4 using LTO5 robotic. But, when i try to do backup, the job was failed because something that i don't understand, and when i see in my NetBackup 6.5, in media menu, all of my media that used to backup job is frozen.
