Most if not all of them I've seen are in the bios of the scsi
controller. But there
is one for linux called scsiinfo. It is in this package
"scsi-1.7_2.22_000630-0 ".
It came with my SuSE dis. Be sure to read the man pages CAREFULLY before
using.
I havn't actually used this one but looks like it will do it. Again be
CAREFULL.
Misuse could cause lost data....
