vmhba lost with no errors logged

[architects]

Hi,

We have a ESX cluster with 3 IBM HS22 hosts. One of the hosts (single FC HBA card with 2 storage ports) suddenly lost both the HBA's. Now i see only the local LSI logic card to which the local drives are connected and my vmhba1 & 2 are gone.

I tried rebooting the host and went into the BIOS, i did check the hba's there and scanned them...the LUNs and everything is displaying fine there but when i boot the hsot it doesnt scan those lun's or find the 2 hba's for some reason.

I have made no configuratio change and everything was working fine. I just moved this host from a cluster to another one...that's the only change.

Any ideas anyone?

Regards,

A

Is it ESX or ESXi that you're using? I would suggest accessing the console or TSM and running lspci to verify if ESX(i) is able to see the hardware . For ESXi also check /var/log/messages. As you look through messages after a reboot you should see a portion of the log file that records the VMkernel enumerating the hardware devices in your host and loading devices for them. It would be worthwhile to load a diagnotics CD and run a hardware check on the blade. You may have a faulty HBA.

Do you have a system or PCI card working with VMDirectPath? Submit your specs to the Unofficial VMDirectPath HCL.

Dave,

i do see the HBA's with lspci but dont see them in the VC on the host "storage adapters" tab.

When i reboot the host and if i go to the BIOS i can see the hba's as well as the LUNs but when the ESX starts loading it does not show me the devices loading.

I am attaching thre output so that we are clear.

If you run lspci -p do you see a module listed for the HBA? Did you have to add any drivers to the install to get support for the HBA?

Dave,

I resolved it by loading the QLA module again....working fine now..

Thanks!

Oh...i rebooted the host and got the same problem again....its somehow not scanning and loading my HBA's and related modules.

Everytime i reboot i have to do vmkload_mod qla2xxx - To load the module and then it works fine.

Isnt there a way to make this permanent and load it with each esx boot everytime. Works fine for the other hosts though...

Anyone seen that before?

Issue resolved by fixing the boot load parameters of the HBA driver.
