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.
