After sending the email I came up with a hack:
for file in sda sdb sdc sdd sde sdf sdg
do
dd if=/dev/$file of=/dev/null count=1
if [ $? == '0' ]; then
hds="$hds $file"
fi
done
But I like this much better:
hds=`awk '{print $4}' < /proc/partitions |grep sd[a-z]$`
I can skip the hardware raid controllers (cciss/ida <--assuming that's a
raid controller) as folks are already doing hardware raid.
Would a scsi cdrom show up under /dev/cd* or might it pose as an sd-device?
(I've never loaded a system with something other than atapi drives it
seems.)
Many thanks,
peter
