I have a PowerVault MD3000i that's been showing signs of aging, I guess. In the last 3 years I had to replace 7 HDDs and 2 controller module's batteries, the second battery instance being last night. After I was done I re-checked the health of the array and it was optimal, the flashing amber light changed to blue and I went home. This morning the same battery on the same controller module is in error, so I am guessing that the module itself is burning the battery or the main board is the culprit.
I'm hoping that I can gather some data and send it to a Dell tech so they can tell me what they see.
Also - before I started the procedure I "stopped the I/O" by turning off the network switch that connects the SAN's interfaces with the servers (2 PowerEdge 2950s). This morning all virtual machines (HyperV) except one were off, but the hosts were online. Do the VMs turn off when they don't find the path to the SAN? I turned them on and they all came back with the "windows didn't shut down normally" message. I can't find anything explicit on the Event Viewer.
Thanks.
