Checking for LUNs in the boot message

Open the /var/log/boot.msg file to confirm that Linux has recognized the ETERNUS Disk

storage systems' LUNs.

The following shows an example (Messages can be scrolled (back and forth) using the arrow

Checking for LUNs with the "cat" command

Use the "cat" command to display the "/proc/scsi/scsi" file, which contains a list of recognized

SCSI devices.

The following shows an example of this.

At this point the Multipath Driver has not been set up yet, so two SCSI devices are shown for

each connected LUN (i.e. if there are 3 LUNs, 6 SCSI devices are shown).
