FAS2650 miniSAS Cable Connections - Need to Swap Ports

[nicholsongc]

What is the best supported way to swap SAS connections in production?

We currently have...

Node1:0a --> Node2:0a

Node1:0b-->Node2:0b

It should be...

Node1:0a --> Node2:0b

Node1:0b-->Node2:0a

I need to swap the connections on Node2 without causing a PANIC.  Any suggestions?

Takeover, swap cables, giveback.

That's a good, safe way to do it. You can also just yank the cables and recable while running.
