FYI:
On HP-UX you might want to use fcmsutil to force a reset of fibre card
as ioscan doesn't do one (in fact it will hang if the fibre card is hung
for some reason).

Yes, I can confirm that I've seen that fairly frequently too, but I
don't have a repeatability case so I haven't done much in the way of
scientific testing to track it down.
In loose terms, one or both of the host or the tape drive, though logged
into the fabric, no longer appear to be so from the DF's point of view.
Some times power-cycling the drive or generating LIP from the host side
(devfsadm for Solaris, ioscan -fn for HP-UX, so forth) or both clears
things up, some times it's necessary to reboot the DF entirely, and I
believe I can recall one occasion on which it was actually necessary to
remove and recreate the "cryptainer" (which isn't a big pain for me
because we use the same key for all tape media, but I can see it being a
bit of a drag). If you choose to tinker around with this without just
bouncing the DF, I recommend checking the status on the DF side with the
CLI rather than the web GUI, whose graphical mapping is a nice idea
except that it bears precious little semblance to reality, in my
experience.
Sorry I can't offer you much more than that (especially you, Steve,
since I presume this is for a customer who's insisting on the DF)... my
solution is to switch to LTO-4 and drop the middle-man on the encryption
(which just means I get to start getting angry about the failure of
standardization in the key management space, but that's a whole separate
rant).

OMG Yes! We got a datafort about a year ago and about every other week I
get into work and all my jobs are hung. It's like my master server just
forgets where the drives are.
If anyone has a solution, I'd love to hear it. I'm still trying to
figure it out.
