Hey.
I have a FAS8200 system (2 nodes) with 2 quad SAS ports slots per node.
In the system i have 4 stacks of IOM6 shelfs, so all of my SAS ports are taken,
I want to install a new shelf to the system with an IOM12.
Can I join two stacks (every stack with 4 shelfs) with aggregates on them without breaking them to free 4 ports for the new shelf?
If so, what's the procedure to do it? Even with downtime.
