QLA4050C in HP DL 585 servers revisited

I've given up the ghost on using the QLA4050cs in my DL585 G1 servers as noted in my previous discussion threads.

I haven't gotten around to redeploying the cards in other servers but I doubt 2 of 4 are bad.

When I removed the cards I noticed something, I had installed the cards in PCI-X slots 2 and 3. Slot 2 is a 133mhz slot and 3 is 100 mhz.

Could this have been the cause of the instability I was seeing?

Sorry! - I'm just an occasional lurker.

I never knew there was any question of their being "supported". I recall verifying they were on the VMware I/O hw compatibility list. HP's response doesn't really surprise me.

I've got a third DL585 G1 that I'm about to bring up. Hopefully, it will also work without issue.

Yes, it's possible this contributed.

I had issues in DL380 G4 systems with regular qla2340 FC cards when I mixed slot speeds. With identical hardware I'd lose paths on the san with one system and not with another identical system. HP boxes seem to be very sensitive to bus timing and irq issues.

Interesting...

FWIW - I have two DL585 G1's with two 4050c's in each (slots 7 & 8). Never had a problem.

Where were you when I asked this question a couple of weeks ago? Smiley Wink

And are you running ESX 3.0.1 or better on it? I know I can get the 4050C card to work in a DL585, just not sure ESX will see the card.

I had no problem with them being seen by VMWare in two DL585

G1 servers, they were just unstable.

In addition I found this:

http://www.hp.com/products1/storage/compatibility/d2dbackup/index.html

under 2)

"Symantec Backup Exec 10.d requires the purchase of a hardware iSCSI initiator adapter for use with iSCSI devices. HP recommends the QLogic QLA4050 Host Bus Adapter, which has been fully tested and is fully supported by HP.[/b] "

Does that mean hp supports qlogic only in windows servers?

The Qlogic site doesn't show any hp servers there:

I was referred to the storage group when I called HP on this who gave me similar information from their storage and backup matrix. When I reported this to VMWare they went back to HP support and got this response.

" No 3rd-party hardware is supported in HP servers unless tested, qualified and re-branded as HP. Unfortunately, the QLogic QLA4050C is not supported in the DL585 G1. No 3rd-party hardware is supported in HP servers unless tested, qualified and re-branded as HP. The final word on which option parts are supported is to be found in the QuickSpecs (see pp. 25, 26, 29 for supported storage controllers):"

http://h18000.www1.hp.com/products/quickspecs/11902_na/11902_na.PDF

I don't think it OS specific. Notice the "no 3rd party hardware is supported in HP servers" quote.

So it looks like they will work in HP servers but are not supported regardless of the OS.

I'm disappointed that VMWare support seemed to spend more energy finding justification to close the call rather than help find a solution.

It sounds like your original issue may have been IRQ conflicts, not a bad card. Can you re-install the QLAs and then post the output from:

cat /proc/vmware/pci

cat /proc/vmware/interrupts

lspci

Thanks

And it also only shows Low-Profile form factors. Does the HBA come with a second faceplate so that it can be converted to fit in in a standard slot?

The 4052c cards I've ordered come with the standard bracket installed and with a low profile bracket in the box. I've only gotten the Qlogic retail versions which are fully supported by IBM.
