Jeff,

You have it down correctly – in the expansion shelves, one disk must be owned by one head, the others can be owned by the other head.  More specifically, it’s slot 1 and slot 0 that matter – this is for SES…

Subject: FAS270c disk ownership

Hi Everyone,
One of our sites has a FAS270c to which they are going to add a shelf (DS14MkII w/ 5 x 300GB disks).  These are the only FAS200-series systems we have and we've never added hardware to them.  We would like to add all the disks to a single FAS270 node.  However, based on what I can see in the documentation, each system must own at least one of the SES disks in each shelf.

This means that one disk must be assigned to node #1 and then the others can all be assigned to node #2.  Do I have it straight?  I'd like to assign them all to node #2 without wasting a 300GB disk on "management overhead".  Is that possible?
