We are going to start a new FC disk loop. The new shelf is DS14mk2 with ESH2 modules and we will connect it to a X2050B-R5 adapter. This is a FAS960c clustered pair running DOT 7.1.1.1 so we will connect the shelf to both heads. We want to do the same thing with a second shelf on the other head.
Can this be done without taking down the filers? I checked NOW and only found instructions for hot adding a shelf to an existing loop,
I have done this a few times and it worked fine for me. I did find that in some cases you will get an extra ASUP about a cluster configuration error, when one node has already completed loop initialisation, but the other node hasn't yet. This will self-correct in like a minute, once booth loops have been initialised.
