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,
A little more info...
We have a downtime scheduled to install the new FC adapters in the heads. We have two new shelves in a new cabinet for which we do not have power yet. If the circuits have been run before the downtime, then we are OK. If not, then we will install the adapters in the heads and connect the shelves later when we have power, but we want to avoid a second downtime for that.
If we must power down the head to add the first shelf, then we can't use cf takeover and giveback because the shelf is connected to both heads.
Another possibility would be to run extension cords to the new shelves and when we get power to the cabinet, switch the power plugs one at a time so the shelves don't lose power.
The netapp cabinet is powered by 220V circuits, and I suppose the outlets in the cabinet are also 220V. Can we run extension cords from 110V circuits to power the shelves temporarily?
