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).
