Gave it a shot on one of my ESX servers. VMotioned all the VMs onto another server while updating this one. After it was rebooted and out of maintenance mode I moved some VMs on to it, ones that didn't really matter if they had a problem, and within minutes they just rebooted. Once they are on the server they seem OK. Just out of curiosity, I moved one back to the Update 2 server and it didn't reboot. When I moved it back to the U3 server it rebooted again. Has anybody else experienced this? I couldn't bring both servers to U3 to see if it was just a compatibility issue between U2 and U3 after the VMotion because I didn't want to have the major servers go reboot.

Agreed, but testing would not have uncovered the 3.5U2 bug.

Updated 4 ESX servers so far and no issues. I upgraded 3 IBM x346 servers thru VI Update Manager plugin to ESXi 3.5U3. The only thing was I had to run it through remediation 3 times. The first time I think it failed because it tried to apply an older patch (U2 maybe). The second time it applied U3 just fine, but didn't install the tools package. Finally I ran the remediate again to install tools.

On the 4th system, a HP bl460c blade, I remediated to ESX 3.5U3. No issues except it too about 50 to 60 minutes to complete. I thought that was kinda long. I plan on doing the next 6 blades just like it this week.

U3 has rendered my NFS datastores unable to come online after a host reboot, and therefore my VMs will not autostart.

I have a thread in this group. I basically have to refresh my datastores to bring them online, then manually start my VMs.

Dave,

I put the old settings in my simple.map, and then rebooted the host.

I could then see the controller properly, but couldn't see my VMFS volume.

I then modifed the LVM.EnableResignature = 1 host setting, and rescanned my storage controllers.

I could then see the VMFS volume.

The funny thing is, after another several reboots, the simple.map reverted to the old settings, but I could still see the storage.

Strange.

Hi,

do you have Virtual Machine Monitoring enabled in the HA options?

According to this post this might be a problem in U3. I have not tested this myslf so far. Anyone else?

This will eventually bite you in the keester.

That option is diabled on all my VMs.
