Preparing for cutover phase when transitioning AIX host data LUNs with file systems
If you are transitioning an AIX host data LUN with a file system from Data ONTAP operating in 7-Mode to clustered Data ONTAP, you must perform certain steps before entering the cutover phase.
Fabric connectivity and zoning to the clustered Data ONTAP nodes must be established.
For copy-based transitions, perform these steps after completing the Storage Cutover operation in the 7-Mode Transition Tool. Copy-free transitions are not supported on AIX hosts.
Stop I/O on all of the mount points.
Shut down each application accessing the LUNs according to the recommendations of the application vendor.
Unmount all of the mount points:
Disable the volume group:
Export the volume group:
Verify the volume group status:
The exported volume group should not be listed in the output.
If there are any stale entries, remove them:
rmdev -Rdl hdisk#
