Re: Physical Disk goes offline when cluster node reboots

If you are booting from SAN, have you read -

Just as an FYI, booting from SAN must be supported by your hardware vendor
or Microsoft won't support it.

Dear Darrek,

Ensuring that you are running the lastest drivers is a good start.

However, as you report that your problem occurs during POST, which is the
stage where the OS is not even loading, therefore I would be surprised if
updating your drivers would improve your situation.

I would think that you also need to check the firmware/bios which is
running
on your Emulex cards, ensure you run the latest firmware, as firmware is
running (or starting to run) during (or just after) POST.

(and if you update drivers, you should update firmware anyway, as the two
go
hand in hand)

Quick question: as this is a SAN envioronment: Are you booting from your
SAN
?

rgds,
Edwin.


I understand that drivers may not solve the problem unless they have
code to interact with a booting FC-HBA gracefully during a POST. Since
upgrading the drivers I still have the problem. I will look for a
firmware update.

I'm booting from DAS.
