I have the following situation
FAS6290, CDOT 8.2.3
It has 2 mixed (SSD & SAS) stacks
- Stack #1: 4xDS2246x600GB SAS + 1xDS2246x200GB SSD (2 x sas cables to controller 1, 2 x sas cables to controller 2)
- Stack #2: 4xDS2246x600GB SAS + 1xDS2246x200GB SSD (2 x sas cables to controller 1, 2 x sas cables to controller 2)
SSD shelves are the first (last) of the stack in both stacks above.
I want to separate SSD and SAS shelves, splitting each of the stacks in 2, WITHOUT SHUTDOWN. That will end with 4 stacks (2 x SAS, 2 x SSD)
If I remove ONLINE the SAS cables between the SSD shelf and the first of the SAS shelves in each stack, will those 2 stacks be automatically converted in 4 stacks?
Can I then close these 4 stacks with 8 SAS cables going back to the controllers to restore the redundant connection?
It is clear I can do this WITH a shutdown, but can it be done WITHOUT?
