I recently had a SCA-2 disk become inaccessible in a zfs pool in
Solaris 10 SPARC. I replaced it, but instead of throwing it away I put
it in my fun server (E450 also Solaris 10). It was detected by format
but it came up as <unknown>. Auto-configure failed. I had a model # so
I got a CHS config from Google. I did a format with these numbers and
I now have the disk back working. But what if I had no CHS config? Is
there a tool that would count the raw sectors for me and then I could
fudge the CHS? Would this work?
