6.0 HP StorageWorks X9000 File Serving Software CLI Reference (TA768-96040, October 2011)

ibrix_umount

Unmounts a file system.

Description

ibrix_umount unmounts a file system from file serving nodes, X9000 clients, and hostgroups.

You can also locally unmount a file system from Linux X9000 clients with ibrix_lwumount.

File serving nodes immediately unmount a file system. For X9000 clients the intention to unmount

a file system is stored on the management console. When X9000 Software services start on a

X9000 client, the client queries the management console for the file systems to be unmounted and

then unmounts them. If X9000 Software services are already running on a X9000 client, you can

force the client to query the management console by either executing ibrix_lwmount -a on

the client or by rebooting it.

The root segment must be the last segment unmounted. Attempting to unmount it while other segments

are still mounted will fail.

If the file system has been exported using NFS, you must unexport it with ibrix_exportfs before

you unmount it.
