We recently received some "new" 9940 media, and have had an unusually
high number of tapes stuck (and unwilling to manually unload) in drives.
I'd been a bit suspicious of this (especially since the media has
older-style "StorageTek" and "Imation" vendor stickers on the side,
rather than the new Sun emblazoning), but the final two straws fell
today.
First, a tape was stuck in a drive on its first mount. A manual unload
did work, but remounting it manually immediately failed with FSC 5132 on
the drive's LCD panel. Those of you who've managed to weasel an FSC list
out of SunTK at some point probably know what's coming here: the leader
block was completely detached from the tape inside, a clean break at the
edge of the plastic.
On a theoretically brand new tape, which I was mounting for the first
time.
Yeah. Right.
And as if that weren't enough, one tape had been frozen during Friday
evening's backups. Here's the bptm log message:
18:31:42.516 [8568] <16> write_backup: incorrect media found in drive
index 13, expected EP1319, found D01087, FREEZING EP1319
That's... curious.
So I vmdeleted my EP1319 and vmadded a D01087 with barcode EP1319, and
then did a bpimport for D01087.
Here's what I got (bpmedialist output first, followed by full bpimmedia
-U output):

I won't name and shame the VAR who sent us these obviously recycled
media (yet), because I don't know their side of the story (yet), but
this is very, very scary. (There may be more of these, we've only just
started to use that shipment of media.)
If you have a host named ag188u, a policy named Puredisk, and you use
the Dxxxxx volser, you need to take a GOOD HARD LOOK at your media
disposal process, because it appears to be broken.
Yet another reason to start taking media encryption seriously, even for
media you don't intend to send off site during its useable lifetime in
your environment...
