First, look into /sys/class/fc_host directory.

You'll find one sub-directory for each FC card you have, e.g. "host0" and "host1". In that directory is a file named "symbolic_name". View that file.

Example:

$ cat /sys/class/fc_host/host0/symbolic_name
QMH2462 FW:v4.04.09 DVR:v8.03.00.1.05.05-k

In this example, QMH2462 is the card model, v4.04.09 is the firmware version, and v8.03.00.1.05.05-k is the driver version.

More information is available in the corresponding scsi_host branch of the sysfs: if the directory name in /sys/class/fc_host was "host0", look into /sys/class/scsi_host/host0 too.

There are several possible multipath solutions. Before you can find the version of the multipath software, you must first identify the multipath solution type.

Multipath solutions:

A) multipath integrated to the HP-supplied QLogic driver:

Run "modinfo qla2xxx | grep ql2xfailover". If this word is found, you're using a QLogic driver that can support multipath failover internally. In this case, look into /etc/modprobe.conf: if option "ql2xfailover=1" is defined for your HBA(s), the driver's internal multipath solution is enabled, and multipath software version = driver version.

B) device-mapper multipath (recommended by RedHat, available in standard RHEL distribution as an optional package):

Run "multipath -l".
If this command lists any multipath devices, you're using device-mapper multipath.
To find its version, run "rpm -q device-mapper-multipath".

C) storage manufacturer's multipath software:
This depends on which multipath software you're running. For example, EMC PowerPath on Linux can be identified by noting that the disk devices (e.g. in /etc/fstab) are named like /dev/emcpower[a-z]*. In this case, see the manual of the appropriate multipath software to find out how to identify its version.
