I've migrated out data from a 2050 to a 2240. The 2050 had an attached ds4243 which is now cabled to the 2240. I'm having trouble assigning the disks as they are currently still owned by the old san. Nothing I do seems to work.
san03> priv set advanced
san03*> disk assign 0b.10.17 -s unowned -f disk assign: Disk 0b.10.17 reservation is not held by this node. san03*> disk remove_ownership 0b.10.17 -f
disk remove_ownership: Disk 0b.10.17 is not owned by this node. san03*> disk remove_ownership -f 0b.10.17 disk remove_ownership: Disk 0b.10.17 reservation is not held by this node.
For completeness in case others come searching, we also were able/had to carry out that same process for one of our HA pairs. It's pretty similar I would imagine - if you're removing FAS2552 or similar nodes from a cluster to convert them to shelves, worth remembering to do this before you pull the controllers and turn them into shelves
In the case of another HA pair in another cluster which had already had the 2552s converted to shelves, we were albe to remove ownership from the SSDs; for the SAS disks we had to 'power cycle' each disk indvidually by pulling it from the shelf, waiting and then reseating. Tedious but it worked!
