Find HBA Firmware Version in Linux – Easy Way

You need to know, what is version of your HBA firmware to upgrade it or install compatible driver version.

There is many ways to find firmware version but I want to share easier way.

Just logon to your Linux machine with Sudo user and run the below command:

cat /sys/class/fc_host/host*/symbolic_name

The result should be like this:

QLE8362 FW:v6.06.03 DVR:v8.05.00.03.39.0-k
QLE8362 FW:v6.06.03 DVR:v8.05.00.03.39.0-k

QLE8362 is your HBA controller model.

FW: … is your firmware version.

DVR: … is your HBA driver version.

This solution has been tested on OLE 6.5 and RHEL 6.6.
