VMSCSI, SYMMPI errors w/ESX server and EVA8000

[gurdeep_2]

I'm running ESX v2.5.2 with an EVA8000
Multiple servers are getting the following system even error logs.
I've found a VM Ware knowledge base article, but I believe the problem to be with a physical HBA on the ESX server...

Has anybody ran into this issue?

Hi gurdeep.

I am experiencing the first error with one Virtual Machine running on a BL20p server connected to an EVA8000.

The problem disappears if I move the VM to another ESX server, so I was suspecting an HBA problem as well. However, the ESX logs don't show anything pointing on that direction.

I am running VMware 2.5.3.

Did you find a way to correct this problem?

Thank you.

I fixed this error by performing following actions:

1) on EVA8000, I changed the OS type to a custom HEX Code to "00000000220008BC"
2) Modify registry in accordance with following VMWare article.

3) The ESX Server and the virtual machine's must be rebooted to get to an optimal state.
I have however occasionally had a problem with that same vmscsi timeout, but the problem has been reduced do literally no errors.

Let me know how it goes. be sure to test with development first!
