Hi,
I apologize if this question is a faq but I'm really new to this mailing
list.
I want to make an HA system with two computers, the md device (and
RAID-1), and Linux.
Indeed, I take two pcs, add an adaptec aha1542 on each, a scsi disk on
each, and I put an external wire (cable) beetwen them.
A pc is a master, the other is a spare one.
When I load the aha1542 module, it sees very well the disk on the
other-side and can make raid (due to md device) with it.
Suppose the other computer breaks down, I would like to know if it is
possible to restart dynamically the scan of the scsi chain.
May be it 's a simple # echo "something" > /proc/scsi/????
Thanks !!
Rodriguez Sébastien
