8. Restart the server and select the boot menu option with the updated RAMdisk image.
When Linux boots up. We want to verify that the QLA2400 driver is properly updated:
a. Run this command:
ls -al /proc/scsi/qla2xxx
Two files should be shown, one for each FC HBA port, as you can see in Example 21-3.
Example 21-3 Two files representing two FC HBA ports
total 0
dr-xr-xr-x 2 root root 0 Jun 20 14:43 .
dr-xr-xr-x 5 root root 0 Jun 20 14:43 ..
-rw-r--r-- 1 root root 0 Jun 20 14:43 1
-rw-r--r-- 1 root root 0 Jun 20 14:43 2
b. Display the contents of these two files with command
cat
:
cat /proc/scsi/qla2xxx/1
cat /proc/scsi/qla2xxx/2
The driver version will be shown in the second line (see Example 21-4).
Example 21-4 QLA2400 driver version
QLogic PCI to Fibre Channel Host Adapter for QLE2462:
Firmware version 4.00.23 [IP] , Driver version 8.01.06
ISP: ISP2432
...
...
...
As you can see, the driver version is now 8.01.06, so the update procedure was
successful.
21.7 Install Linux RDAC
RDAC for Linux can be downloaded from the IBM Systems support Web site. The IBM Web
