ECC Errors On Nutanix

When logging into a Nutanix cluster I see that I have 2 critical alerts.


With a quick search I found KB KB 3357 I SSH into one of the CVM’s running on my cluster, and ran the following command as one line.

ncc health_checks hardware_checks ipmi_checks ipmi_sel_correctable_ecc_errors_check

Looking over the output I quickly found this line.


I forwared all the information to support, and will replace the faulty memory module when it arrives.  Luckly so far I have not seen and issues from this memory issue, and I really liked how quick and easy it was to resolve this issue using Nutanix.

vCenter Fails after Time Zone Change

We recently changed our NTP server, and I needed to update all or hosts and vCenters.  I have a handy powershell script to update the ESXi hosts, but that script does not work on the vCenter servers.  I log into the server using port 5480 to gain access to the vCenter Management. I login as root and notice that the time zone is UTC.  I am in the Central time zone so I wanted to change it from UTC.  Turns out if you do that it break everything.  I had to learn this the hard way, and once I changed the time zone I was not able to log into vCenter.  I had to then go back and change the time zone back to UTC to regain access. Capture.
