Following on from yesterday’s EOY backup topic for ESXi, today I’ll document how to automate the backup of your VNX & VNX2 Array configurations. As usual, I want this to be automated, set-and-forget and reliable. A combination of NavisecCLI and Powershell works beautifully for this. Without any doubt, the best documentation Continue Reading

EMC Unified VNX — Unisphere AWOL !
Unisphere can sometimes be a fickle beast, particularly with java versions and compatibility. I had a very strange issue with Unisphere a couple of weeks ago where it would not allow any logins.
