Quick-Take: ESXi Patch Released

Thanks to a tweet from Duncan Epping at Yellow Bricks, we've installed the latest ESXi patches to combat the unexpected vCenter problems reported with Update 1 for vSphere. While we've not experienced the vCenter problem in the lab, enough of users out there have caught it for VMware to issue a "not recommended" warning for ESXi users.

VMware ESX & vCenter Server Alerts

ESX 4.0: If you plan to upgrade ESX 4.0 to 4.0 Update 1 (fixed in 1a), it is critical to read KB article 1016070 before proceeding with the upgrade (affecting HP Proliant Systems w/Insight Agents).

vCenter Server: vCenter Server: If you have ESXi hosts connected to vCenter Server 4.0, please do not upgrade vCenter Server to Update 1 before installing the patch (ESXi400-200912001) referenced in KB article 1016262.

SOLORI's Take: reinforces the concept of patch regression in lab or non-critical cluster... Work with your VMware professional(s) to manage VMware/vSphere patches and updates whenever possible.
