If accidental changes are made to the storage cabling during the upgrade, perform the following procedure to change the storage configuration back to the correct state.
This procedure assumes that no physical storage was actually changed. If physical or logical storage devices were changed or replaced, instead follow procedures in How to Handle Storage Reconfiguration During an Upgrade.
Change the storage topology back to its original configuration.
Check the configuration of the devices that were flagged as possibly being replaced, including the cabling.
As superuser, update the DID driver on each node of the cluster.
