This week it has been my goal to learn vCAC and during this time I have been running into old remnants of past labs that have been causing me problems. I was finally getting around to installing my IaaS VM and I kept having the VM BSOD during the install and instantly my host would PSOD. Since I don’t have a KVM I had to just hard power it and wait for it to come back up.

Checking in /var/core I find the following


Well that isn’t great but atleast we have a core and with a core we can find out what happened (usually). So after talking to my cousin Dillon I found out there was a tool that we can use

esxcfg-dumppart -L dumpname

This will output the results in the current working directory where you run the command. In my case it was in /var/core


If we look at the log we can see the following


After doing a bit of  talking to Dillon and Googling we can find this which turns out is a known issue and the only fix is to upgrade.

Turns out I haven’t updated this host in a while.


Since I am currently only running 1 host in this environment I am using the script from with the new package number for 5.5 U2

esxcli software profile update -d -p ESXi-5.5.0-20140902001-standard

Lesson learned….keep my lab hosts up to date before I start new side project goodness.
