Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

[EU-Admins-UNIX]

Hi All

We are going through some remediation tasks as part of a SAN switch migration project.

Some of our FC HBA drivers are out of date and need upgrading.

We currently have:

FibrChanl-00                          B.11.31.0903   FibreChannel;HW=A6795A,A5158A

but upgrading to:

FibrChanl-01                          B.11.31.1311   FibrChnl;HW=A6826A,A9782A,A9784A,AB378A/B,AB379A/B,AB465A,AD193A,AD194A,AD300A

So upon installing the latter version, the fcmsutil /dev/fcdx shows the upgraded driver version.

BUT:

How does one revert if one has to?

I swremoved the latter version, leaving the older version (swlist showing only the older version), rebooted, and lost site of my HBAs, storage, etc.

root@labunix2 at / =>swlist | grep -i fib
FibrChanl-00 B.11.31.0903 FibreChannel;HW=A6795A,A5158A

I re-installed the new version again, rebooted, and it all came back.

My issue is I need to put a reversion plan together, ie how to re-instate the old driver version.

You did not upgrade, these are different drivers for different cards!

FibrChanl-00 vs. FibrChanl-01

You can see the supported cards already in your first post.

IIRC FibrChanl-01 depends on FibrChanl-00, so update both drivers!

[EU-Admins-UNIX]

I see.

OK, so on my test box, you can see I originally only had:

FibrChanl-00                          B.11.31.0903   FibreChannel;HW=A6795A,A5158A

Is there a later version of the above FibrChanl-00, ie later than 0903?

Storage was all visible with 00.

When I installed the later 01 version, both versions were installed in swlist.

Also fcmsutil showed the Driver version now being the 01 version.

So, when I removed 01, why didn't the HBA's revert back to using 00 after the reboot?

You should never do a "swremove", just install the new version.
Depending on the options used you maybe corrupted the "old" driver.

[EU-Admins-UNIX]

I never removed the old FC-00, just installed the new FC-01 version, and fcmsutil just showed the Driver using FC-01 after reboot.

SO, it's OK to 'upgrade' from FC00 to FC-01?

Is there any problem running both?

As said, AFAIR the -01 driver requires the -00 driver as base.

It looks good now.

[EU-Admins-UNIX]

Excellent, thank you.

If one cannot swremove, do you know how one would revert back to using the base 00 version, other than re-ignited from a make recovery tape?

[Torsten.]

As far as I remember I never downgraded any driver in more than 15 years ... ;-)

Hi,

I think you are getting mixed up. what I think Torsten was triying to explain in the first post is that FibrChanl-01 is not and upgraded version of  FibrChanl-00, they are different versions for different model of cards

In your post you specified:

We currently have:

FibrChanl-00                          B.11.31.0903   FibreChannel;HW=A6795A,A5158A

So what you need to update the firmware/driver is a newer version of FibrChanl00(not FibrChanl01).

The latest version is:

HP-UX 11i v3 (B.11.31.1003)

https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=FibrChanl00

If you need to downgrade just reinstall your old driver depot(you need the software):

FibrChanl-00                          B.11.31.0903

Hi

We have fcd cards, as opposed to td's:

fc 2 0/0/6/1/0 fcd CLAIMED INTERFACE HP AB378-60101 4Gb Single Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)

Therefore I think FC-01 will be the correct version.
