Find HBA Firmware version for HP branded HBA

[rginjupalli]

cat /sys/class/scsi_host/host2/fwrev
1.11A5 (U3D1.11A5), sli-3

I thought, above command displays HBA FW version. I have HP 8GB Dual channel PCI-E FC HBA. On HP website, I see current version for my HBA model as 2013.08.01. 

Firmware - Storage Fibre Channel Description Current version Size (MB)

• 2013.08.01
• 10 Sep 2013

I am confused with variation in the version numbers. Can any one please clarify, on how to find the HBA firmware version from OS?

"HP 8GB Dual channel PCI-E FC HBA" does not uniquely identify the HBA model.

HP has at least two HBAs matching that description.

One of them is Qlogic-based:

http://h20566.www2.hp.com/portal/site/hpsc/public/psi/swdHome/?cc=us&cc=us&lang=en&lang=en&sp4ts.oid=3837184

Another is Emulex-based:

http://h20566.www2.hp.com/portal/site/hpsc/public/psi/swdHome/?cc=us&cc=us&lang=en&lang=en&sp4ts.oid=3741531

Your /sys/class/scsi_host/host2/fwrev output looks like Emulex firmware version number syntax.

Looking at the download description page for the RHEL 6 firmware update for the above-mentioned Emulex card,

it looks like 2013.08.01 is the version of the package containing a collection of Emulex firmwares + a Linux firmware flashing tool.

By checking the "Enhancements" page, you will find the actual firmware version numbers contained in the package:

http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3741531&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D1%257CswItem%253DMTX_ed6e3c3faf7543fdbc136579ee%257CswEnvOID%253D4103%257CitemLocale%253D%257CswLang%253D%257Cmode%253D4%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.v...

According to that (in case that awkwardly long link does not work), the 2013.08.01 package contains firmware version 2.01A4 for the 8GB Emulex HBAs (exception: version 2.02X6 for HBA model LPe1205a).
