VMware would like to inform you that they are experiencing a delay in releasing the new version of ESX/ESXi 3.5 Update 2. Their testing of this release is taking longer than anticipated. They are now targeting to release the update between 2:00 AM PDT (0700 UTC) August 14 and 8:00 AM (1500 UTC) August 14 PDT. They apologize for the delay. VMware engineering teams are working around the clock to deliver this new version. They will continue to keep you informed of developments until this issue is fully resolved.
In our last update, we referred to an initiative by our support and engineering teams to find an option to apply the patch without the necessity of entering maintenance mode and VMotion of VM’s to other servers, or VM power-off and re-power-on. Our earlier tests have not found a consistently successful way to address this. We continue to investigate this possibility, as we know that it would reduce the maintenance burden on our customers who may not have a patched server available for VMotion.
