VMware Update Manager U3e upgrade failing? Un-install it!

VMware Update Manager U3e error

I was recently upgrading a VMware environment from vCenter Server Update 3b to Update 3e and during the scheduled change I had also planned on upgrading VMware Update Manager to Update 3e and ran into the following error:

VMware Workstation unrecoverable error: (vthread-3)
GetProcAddress: Failed to resolve ENGINE)load_aesni: 127
You can request support.

Looking for a possible solution at the VMware Knowledge Base came back with no results and to error message wasn’t overly useful either with “VMware Workstation unrecoverable error: (vthread-3)” as Workstation wasn’t installed on this server.

Just recently we have some hardware issues in our primary datacenter and during that time had a few VM’s that became unresponsive and needed to get them back online. The VM’s had stopped responding to the normal vSphere commands to reboot, shutdown or even restart. I didn’t want to power cycle the entire ESXi host and instead just power off an unresponsive VM.

Here is a quick and easy way to do just that using ESXTOP.

Just a quick heads up! Over the last week I’ve been upgrading our vCenter servers from version 5.5 to the most recent 5.5 Update 3b version and have ran into a small hiccup.

The upgrade of SSO, Web Client, Inventory Service and even vCenter server all went as expected without any issues. Then I rebooted the vCenter server and after the reboot noticed that the vCenter server service hadn’t started and when I tried to start it manually I then received the following error:

Error 1053: The service did not respond to the start or control request in a timely fashion.

Another CBT bug found in VMware ESXi 6.0

VMware

VMware just published KB 2136854 regarding a new bug found in ESXi 6.0 that causes virtual machine backups, which use Changed Block Tracking (CBT), to be inconsistent. VMware says the cause of the issue is this:

This issue occurs due to an issue with CBT in the disklib area, this causes the change tracking information of I/Os that occur during snapshot consolidation to be lost. The main backup payload data is never lost and it is always written to the backend device. However, the corresponding change tracking information entries which occur during the consolidation task are missed. Subsequent QueryDiskChangedAreas() calls do not include these missed blocks, hence a backup based on this CBT data is inconsistent.
