Moving some storage around this evening created a situation where my primary VM datastore was imported on one of my hosts with a new signature file. This had repercussions on the other host in the cluster, causing a situation where when the datastore was being detected through the iSCSI adapter, but not being displayed in the storage window.

Updating to ESXi 5.5 was a pretty straightforward task overall. One of my ESXi hosts upgraded without any complications. The second host hung during “relocating modules and starting up the kernel” of the initilization of the installer.

The storage that is running blog.destephen.com is a product of several iterations of lab Network Attached Storage (NAS) setups.

Initially this blog was setup with https using a self signed certificate. I did always intend on updating the certificate with a “real” certificate to avoid web browsing errors. This certificate would also need to handle other sites/services at destephen.com. This is my first effort at installing certificates that needed to be recognized on everyones browsers.
