we are in major trouble.

one of our fileservers is an AIX 4.3.3 running on a f50, with external
80-pin SCSI drives in a tower attached to a SCSI card in the f50.

last friday, the SCSI card for that tower failed, and all of the
filesystems on that tower are screwed! im so pissed. i can't mount any of
the filesystems, it just says I/O error, and i run an fsck, but that
doesnt fix it. i think the whole super block is totally lost.

so, im trying to restore all those drives from tape. we have a 3575 tape
library and run adsmserv 3.1 on that same AIX machine. there are 8
filesystems that i need to restore. i started with one last night, it was
going fine, but when i woke up this morning, it had stopped about 1/2 way
through and complained about data unavailable to server. it only restored
about 7GB when i know there is about 18GB on that filesystem.

i tried running the dsm client again, and chose not to overwrite any data,
but as soon as i start it, it just hangs there, doing nothing. maybe its
still comparing all the 7GB of data that is already restored, but it
doesnt say anything about that, it just says transfering...

is this normal, or is something not working?

also, i looked at the tapes in the library, and there are 2 marked as
unavailable. those tapes were not unavailable 2 days ago!! what happened?

any ideas?

man, if i cant restore this data, we are so screwed.
