You must unmount a shared file system before upgrading hardware. Before you unmount a file system, you must idle or stop any archiving operation that is in process.
Note - Before you can unmount the metadata server for a shared file system, you must unmount each client and potential metadata server that is participating in the shared file system.
To unmount a metadata server for a shared file system:
The File Systems Summary page is displayed.
The File System Details page is displayed.
The metadata server is redisplayed with the unmounted value in its Mount State column.
