Controller ID's in Red Hat 5.1

rhgarcia · 10-09-2009, 06:39 PM

I am migrating from a DMX2000 to a DMX4000 and cannot figure out how to tell which lun is from which SAN unit. I come from the Solaris world and am used to the disk name and format indicating the controller. Is there something similar in Red Hat? This is on an HP Blade Server. Any help you can give me would be appreciated.

Hi,

disk naming scheme in Linux is different from Solaris. As you address to controller/target/disk/slice in Solaris, there is nothing similiar in Linux. Linux only uses /dev/sd* naming.

To check which device represents which LUN you have to check /proc/scsi/scsi
