"cat" command for LUN display

•

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

The following shows an example:

# cat /proc/scsi/scsi

Attached devices:

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

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