You simply add a second path between enclosure and controller, example:

See enclosure user guide for details.

Hi,

Please check the cabling diagram for D3600 on below link for Single/Dual Domain configuration:

https://support.hpe.com/hpesc/public/docDisplay?docId=c05105559&docLocale=en_US#N1013C

Your current configuration appears like two separate Single domain setup with two enclosures in each,

and both connects to same controllers.

Now what are the alternatives you have:

1. Continue with two Setup with Dual Domain->

>Add an additional P441 controller,

>Move one setup to One controller [Connect 1E port of each controller, and use 2E of each controller for Dual domain

cabling]

>Follow the cabling diagram to create Dual Domain setup:

Add two cables : Enc1: I/O B P1->Enc2: I/O B P2 & Enc2: I/O B P1 ->Port 2E of the controller

2. Build a Single dual domain setup with 4 x Enclosures,

In this case you need to break on of the setup and join or cascade them behind the other one to make one single setup of 4 x Enclosures, also free up 2E Port on the controller,

-Follow the dual domain cabling diagram you have mentioned which is correct or refer the above HPE cabling article.

Note:

In any case its strongly recommended to have complete data backup before implementing Dual domain cabling.
