Dismount allows you to maintain or repair a volume and to upgrade disk drivers while the NetWare server is up.

Use this command to dismount all volumes residing on a removable drive before you remove the drive.

If you are running out of memory and cannot add more RAM, consider dismounting a volume that is used infrequently.

Mounted volumes take up memory allocated for file caching and thus affect server performance. NSS volumes use much less memory than Traditional volumes.
