Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

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Some of our FC HBA drivers are out of date and need upgrading.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 / =>ioscan -fnCfc
Class I H/W Path Driver S/W State H/W Type Description
================================================================
fc 0 0/4/1/0 fcd UNCLAIMED UNKNOWN PCI-X SerialBus (10772422)
fc 1 0/4/1/1 fcd UNCLAIMED UNKNOWN PCI-X SerialBus (10772422)
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.

 

Regards

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!


Hope this helps!

Re: Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

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.


Hope this helps!

Re: Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

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?

Re: Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

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

It looks good now.

Hope this helps!

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?

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

Hope this helps!

Re: Fibre Channel Driver Upgrading/Downgrading HP-UX 11iv3

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

Windows?, no thanks

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.

Yes, sorry.

 

The same applies, you need the newest version of the -01 version (not the -00  version).

Ah!

 

FC00 for tachyon (td)

FC01 for Qlogic (fcd)
