We had an issue last night with a ESX 2.5 Virtual not coming back up. The virtual (Windows 2003 Server SP2) was taken down and memory added. When the box was powered back on it got past the black Windows loading screen but it never got to the blue splash screen. It was hanging in between. I removed all of the disks and added them back one at a time. I discovered that when certain disks were added the box would hang. With others it would come right up.
My question is "What is Windows doing at this point". We could ping the box so the network services were started. But all we were getting was a black screen.
We did discover an array on an MSA1500 where the VMDK's were stored was rebuilding from a drive failure.
My other question is "Would a virtual be prevented from coming back up if a 0+1 array on an MSA1500 is in the process of rebuilding?"
Its redundant so I wouldn't think it would be stopped by that but thats what looks like might have happened. I'm guessing these two had something to do with each other but I can't prove it. It might be coincidental that the two were discovered at the same time.
