•Checking for LUNs in the boot message
Open the /var/log/boot.msg file to confirm that Linux has recognized the ETERNUS DX Disk storage systems' LUNs.
The following shows an example (Messages can be scrolled (back and forth) using the arrow keys).
<6>qla2x00_set_info starts at address - c3600060 <6>qla2x00: Found

•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.
#cat /proc/scsi/scsi Attached devices:
Host: scsi0 Channel: 00 Id: 04 Lun: 00

| |||
Vender: FUJITSU | Model: ETERNUS_DX400 | Rev: 0000 | ||
Type: |
| ANSI SCSI revision: 05 | ||
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).
