not sure how to translate all that. I guess what I need is find out the address of my spare drive without rebooting the system so I can create a volume group on it.

What is you space drive?
for scsi : /dev/sdXX (sda,sdb ...)
IDE : /dev/hdXX
from SAN: /dev/sdXX - check with qlogic or other driver utilities.

Re: ioscan equivallent in linux

Ivan Krastev — Tue, 14 Oct 2008 19:55:54 GMT

You have one SCSI disk (sda1), mounted under /vol and one visible from HP array controller (/dev/cciss/c0t0) with 2 partitions: normal Linux c0t0p1 (/boot i assume) and LVM partition c0t0p2.

Check in dmesg for any additional disks - next disk from array should be visible as /dev/cciss/c0t1.
use:
dmesg | grep -e cciss -e disk

lshw -businfo

lshw also has an output mode that is similar to ioscan with certain options.
