7400 / 4 Node add 8 Shelfs on simplest way

[LCW]

Hello

what is the simplest way to add 8 shelfs to a 7400 / 4 Node with 6 Shelfs.

I think shutdown the Storage, add the Shelfs to the storage (guide=> 3PAR cabling guide).
start the storage, admithw, tunesys.

Thanks
regards

You can do it without stopping the array.
Don't forget cages are connected to nodes with two loops.

(6+8) / 2 = 7 cages per nodes cluster.
So you are planning to have CPGs with ha cage and raid 5 6+1 ?
Right now you got ha cage with raid 5 2+1 CPGs ?
