We're not using HW compression, as far as I can tell. There is no
reference to it in the tapetype (but that might not be where it's
specified) or in the chio glue script.
Further digging revealed the following in the dmesg:
(sa0:ahc1:0:6:0): UNIT ATTENTION csi:0,0,0,44 asc:29,0
(sa0:ahc1:0:6:0): Power on, reset, or bus device reset occurred
(sa0:ahc1:0:6:0): failed to write terminating filemark(s)
(sa0:ahc1:0:6:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM
command to
clear this state.
So it looks like we did have a hardware problem. I think I'll hop over
to freebsd-hardware and ask what this is about (there's some other stuff
about "SCB" entries that I don't understand). If anyone else using
FreeBSD has seen this type of problem, please email me off-list.
Thanks!
