I'm running the Equallogic MEM Driver 1.1.2 on all datastores on all hosts.Īny help, advice or direction is much appreciated. I'm looking to update to 6.0.2 to benefit from the VAAI iSCSI UNMAP feature as well as simply keeping it up to date. If that's the case how are the Hosts / VM's going to react to this? Also will there be issues with my volumes being stretched across both arrays when I suddently lose connectivity to half of each volume?

I want to avoid crashing all the VMs obviously.Ī few people at EqualLogic said it should be fine updating the firmware on an array and it will update the firmware one controller at a time and then switch the passive controller to active though there could be up to a 30 second delay. We are running a few hundred VM's currently so the option of pausing them all then unpausing isnt really there.

We currently have two PS4100VX arrays in a single Group, the volumes are balanced across these two arrays.īoth arrays are running firmware version 5.2.2, and the total usage of the Group is about 70% capacity.ĭue to the capacity I am unable to evacuate the volumes to a single array for for the firmware updates. I've contacted Equallogic a few times and I cant seem to get a straight answer from them regarding this and I want to be 100% sure before undergoing this proceedure.
