I'm sure this information is somewhere, but I can't find it. I've read all the guides on the NOW website.
I have a FAS2240-2, with an old fibre attched disk shelf.
At the moment head A uses the internal disks only and head B uses the fibre attached disks. The fibre disks are fine, and this bit won't change.
For the internal SAS disks, I have the SAS and ACP cables running between the 2 heads, so in the event of a failover, they can take over from each other, this has previously been tested.
I need to install an extra shelf of disks, we've got a DS2246, and I'm looking to make all disks available to Head A only.
After my long winded intro, my real question is, can I remove the SAS cable from head B end, so I can attach it to the new disk shelf, before adding the others in, without taking anything offline, or warning the system I'm about to disconnect a cable?
Then I will need to do this with the ACP cables, is this the same.
