Frozen Tapes - Lots of them
Netbackup 7.1.0.4, Windows 2008R2 with two Windows 2008r2 media server, two Dell ML6000 libraries with 6 drives each.
Hello all,
Im seeing something odd with media freezing.
I loaded up both of our Dell tape libraries with enough media to run through the entire weekend, into Monday. I do this every Friday afternoon. As of typing this (the very next morning), I started seeing some error 96's showing up. I know what that means, so I knew it should not be happening. I looked and I see that about 50 tapes total between my two libraries went into "frozen" status. What is especially odd to me is that in Library 1, about 30 tapes all went frozen at exactly 7:52:09. I know there are various reasons why tapes can go into a frozen state, but this happened in both libraries, and multiple tapes, so I can discount bad media or drive issues, especially since they all went frozen at the same second. Have any of you seen this behavior before?
Thank you!

Uhhhhg! Ok, I figured it out. Its kinda stupid, really. In our storage room was a tote full of tapes. These were set aside as sort of a "rainy day" supply of tapes in case we went low on inventory, and needed an emergency supply. Well, I needed to tap into those, so I inventoried a batch and they went straight into the scratch pool and started writing and I commenced to loading more batches. As it turns out, once upon a time, long before I took over backups for the company, Netbackup was set up to use the first 6 characters of the barcodes. I use the last six, i.e. 004132 vs 4132L3. All I can figure is that the change was made sometime in the middle of that batch of tapes. I suppose Netbackup could not read the tapes with the internal media ID set to the first 6 characters, so it immediately froze those tapes. I now have my new tapes and labels, and all is well. Live and learn.
Thanks all. This can be resolved.
