Anyone has any solution the intermittent problem which I'm
getting with the ESX hosts which connects to a HDS SAN via
a FC switch below:

I've already applied the latest IBM x-series firmware
but doesn't seem to help

Are you getting "ALERT: APIC: 1823: APICID 0x00000000 - ESR = 0x40" in the log or did you post the wrong document?

I was told by one of the customer's VMware support that it's a known bug
& certain settings in the kernel is needed.

Thus "certain ESXi Kernel Settings is needed to resolve FC Connection lost issue"

We have yet to install the ESXi hosts but customer pre-warn us.

Basically, we'll see "ALERT: APIC: 1823: APICID 0x00000000 - ESR = 0x40 "
& we need to fix this by issuing at ESX (in our case it's Ver 5) by issuing:

esxcli system settings kernel set --setting=iovDisableIR -v TRUE

Guess I've answered the question myself : I should read what I
posted rather than just copy whatever customer gave me & paste
it here in EE
