Check out these two links. Everything should work… but it doesn’t always.
Shutdown the cluster
– Disconnect the iSCSI connections
– Move the LUNS on the storage side.
– Offline the old LUNS
– Connect a node to the new storage, check disks appear in disk management as ‘reserved’
– Start the cluster, make sure everything is OK then apply to other nodes.
I added a shutdown of one of the nodes in one of the following steps.
- From cluster manager,
- right click on the cluster
- go to More Actions,
- select Configure cluster Quorum Settings.
- Change from Node and Disk Majority and switch to only Node Majority.
- Once that is complete, disconnect the old LUN from the cluster.
- Add the new LUN to the cluster
- Go back to quorum configuration and switch back to node and disk majority.
The cluster software writes a disk signature to each drive (LUN) and that is how it keeps track of them. If you preserve the complete contents of the LUNs, it should not have any issues recognizing them on a different IQN.
