I have a backup VMware server running on a Dell PE R710 that has been working fine for a year. It's just a backup/test unit that doesn't get used much. It has VMware ESXi 4.1 update 1 installed and was working fine until I tried to turn it on yesterday and the boot process just hangs. NOTHING has changed on it. It was running fine, powered off, then powered back on after a few weeks of not being used. No hardware changed, no updates applied, just powered off and back on.
Pressing ESC during boot up shows that the last line displayed reads:
Booting: MBI=0x000100c0, Entry=0x00400256
All the searching I have done so far involves problems trying to do a first install of VMware, which is not what I'm doing. This was a fully functional VMware host a couple weeks ago that ran virtual machines just fine and today it will no longer boot.
So far I've done the following with no help:
1. Ran Dell Diagnostics, no errors reported
2. Reseated RAM, Hard Drives and the bootable USB drive
3. Left it running over night but it's still at the Booting: error above
Does anyone have any insight on why a previously booting VMware host would suddenly stop with this error?
