FAS3020 Repourpose, adding shelf from DECOMM FAS940

Sorry, I know it's a lil confusing, I've been scatterd all over the place. Here's a list view of each system.

(1) FAS3020

(3) DS14MK2 Shelf's

(4) ESH2

(2) ESH

Left over Parts:

(1) FAS940

(6) ESH

(2) ESH w/LC

(4) DS14MK2 Shelf (2 are spare shelf units with power supply's only)

I believe the best end goal to utilize both systems is to have the FAS3020 with the 2 ESH2 modules and 1 ESH moduled terminating the the loop. This would allow me to use the remaining ESH module w/LC in the FAS940 terminating the loop with the last ESH module.

I have verified all loop speed settings are set to 2Gb via the switch on the shelf's and all modules are 2Gb capable.

As far as I know it is termination. The ESH2 modules are suposed to be auto terminating, so there's no switch on the back like the ESH module. Here's the output of the 'storage show hub' from maintenance mode:

FAS3020 Repourpose, adding shelf from DECOMM FAS940

After banging my head consistently on the desk, I rechecked cables and loop connections.....and by nothing other than a dumb mistake and grabbing the wrong Molex connector for the ESH cards.....it turns out I mistakenly didn't notice I was using the Molex connector for the ESH module in the ESH2 modules. Obviously, this was what was causing the shelf not to be recognized in the loop. Using the correct Molex connectors for the ESH2 modules alleviated the problem. Thanks, and glad it was just a simple cable mismatch.

Glad you got sorted. I was a bit worried about why it wasn't working for you.
