The driver version and information of each LUN's SCSI device name, etc. are displayed in the
console message when Linux is booted up. Although this console message disappears soon
from the screen, it can be re-displayed using the following command:
8.2.1
For Red Hat Enterprise Linux
The driver version and information of each LUN's SCSI device name, etc. are displayed in the
console message when Linux is booted up. Although this console message disappears soon
from the screen, it can be re-displayed using the following command:
•
"dmesg" command for LUN display
Use the "dmesg" command in order to confirm whether Linux has recognized the LUNs in the
ETERNUS Disk storage systems.
The following shows an example:
•
"cat" command for LUN display
Use the "cat" command to display the "/proc/scsi/scsi" file, where you can confirm the
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).
