Fas 2240-4- add adidional DS4246 Disk Shelf

thomas382 — Wed, 04 Jun 2025 12:06:35 GMT

Hello;

I have a FAS 2240-4 Single Head with one DS4246, and want to add the next DS4246.

My Plan tooks like this:

1. Cabling of the ACP correct (picture i found ihe forum)

2. Cabling the SAS, connect the Controller with the new Shelf firt, then connect Shelf 3 with Shelf 2.

Is this a way to do it with no ninterruprion?

What do you recommend?

Many Thanks, Thomas

Shelf adds are typically done with no disruption, just disconnect one cable at a time.

The ACP looks good in the drawing.

I would add the new shelf to the end of the stack.

Just a suggestion. You will be doing one side at a time from the controller, after you connect one side of the new shelf, you may want to run "storage show disk -p" to see both paths. This can be run in the nodeshell in cmode. After the first path is connected to the new shelf, you should see 2 paths to all disks except for the new shelve's disks.
