I’m curious about all of those EQL users out there, do you use the web GUI for your firmware upgrades or do you use the CLI?
After reading the post below I think I’m leaning towards the CLI upgrade, you?
During the upgrade I recieved a Kernel Panic and subsequent Panic Recovery, looks like the controller crashed during the update this resulted in the iSCSI targets being unavailable for a couple of minutes, the controllers did not fail over and I now have a Firmware mismatch.
Spoke to EqualLogic support, according to them there is a rare issue with FW Versions 5.1.x that in when you process a firmware update using the Java based Group Manager GUI, there are instances when the firmware file becomes corrupted. Support siad that this is a very rare issue and that it will be addressed in further updates.
