Best choice for HBA in L2000 / 11.00

I will very soon be connecting three L2000s to a 2Gb FC fabric. I'd like to hear some opinions from those who have more experience what is the best model HBA for the L2000 with HP-UX 11.00. Best performance / least problems.

Patches are up to date, but likely that any FC patches weren't installed because I have never had an FC adapter in the system. I will be installing the latest bundle at next shutdown, but would like to go ahead an put on all patches req. for FC at that time.

Thanks in advance...

afaik you have not many choices:
A5158A (1GB) or A6795A (2GB).

but maybe Emulex or QLogic Adapters are also supported? I don't know.

We use both the 5158 and 6795, and did not have any problems with them, at least as far as I can remember.
Only the 6795 supports 2GB speed, so of course it is faster.

Yes, I was looking at this card on HP site. Interesting that HP doesn't mention L2000 on the product support list - only new models. Marketing thing, I'm sure.

Greg,

the A6795A 2Gbit FC card is what you want.

The L-class models 1000/1500/2000/3000
have been renamed rp5400/rp5430/rp5470, as you guessed just a marketing issue.

What about patches? Is there a patch bundle for FC support?

Ah, thanks Bernhard. I thought the "rp" and "L" may be the same, but wasn't sure.

Greg,

in fact, your L2000 is an rp5450. Regarding patches you should make a depot with the driver which you should swcopy from the latest Application CD# 1 you have.

Then go to the patch database of the ITRC
and select patches PHNE_25684, which will upgrade the PDC firmware to 41.39. You need this to support the A6795A.

Next select PHKL_23939 and PHSS_26798, download these with all their dependencies and put them into the depot of the card driver.

I recommend to upgrade PDC FW in a single, separate first step. After reboot just install your depot with driver and patches.

Regards,
Bernhard

P.S. I was assuming you run HP-UX 11.00

Greg,
The release notes of A6795A says http://docs.hp.com/hpux/pdf/J2635-90018.pdf - >Compatiability Information and Installation requirements ->Software requiements.

The following are the patches listed out.

â ¢ Tachyon patch PHKL_23939 or later (only for HP-UX 11.00)
â ¢ Tachyon patch PHKL_23626 or later (only for HP-UX 11i)

You will have to do addition research on the latest and pre-requisites of the above two patches.

HTH
