vCenter Crashes After Applying ESXi Patch ESXi410-201010401-SG

My last post described a problem I experienced with VMware HA after upgrading to vSphere 4.1.  Here is my experience with a similar issue after applying the ESXi410-201010401-SG patch to one of my test/dev ESXi clusters.  The patch, released on November 15th and weighing in at a hefty 212MB, fixes a number of issues from Likewise authentication on ESXi hosts to allowing configurable NOOP timout and interval values for faster failover of certain iSCSI arrays (like the DS3300 or MD3000i). The environment where this problem occured has a single vCenter server managing both a production cluster … [Read more...]

With the exception of the specific systems referenced below, the following BIOS settings … [Read more...]

Double-Check the HCL

I wrote some time back about networking problems with a clean install of ESX 3.5 U3 on a HP DL380 G3 server in a lab environment.  A simple downgrade to ESX 3.5 RTM corrected the issue and I didn't think much about it.  One of the servers in the lab died and I went about the business of rebuilding it.  Having learned my lesson, I started with an ESX 3.5 RTM install and then patched to Update 3 plus other applicable updates.  Much to my chagrin, the server began crapping out on me randomly.  Some reboots, some networking issues, and other assorted not so good things.  Now the DL380 G3 is not … [Read more...]
