Hi

I'm about to do a DD860 Extended Retention upgrade and cannot find any documentation that tells me about adding the extra SAS HBA and how to do the cabling. Currently the system has 5 shelves and 2 SAS HBAs. The current SAS cables are attached to Ports 2a, 2b, 3a, 3b

If I look at the EMC Solve cabling document for 6 shelves, it shows shelves 1, 2, 3 and 4 attached to Ports 1b and 3a. And shelves 5 and 6 attached to Ports1a and 2b. Do I have to rearrange the cables or can I just use another 2 ports for the 6th shelf?

Many thanks

Ian
