SYNOPSIS
- umount { vob-tag | –a·ll }
DESCRIPTION
The unmount command deactivates
one or more VOBs on your host by unmounting them as operating-system-level
file systems. A VOB is activated on a host by mounting it as a file system
of type MVFS (ClearCase multiversion file system type). The VOB tag by which
an individual VOB is referenced is the same as the full pathname to its mount
point.
Note: On UNIX, umount calls
the standard umount(1M) command.
Unmounting All VOBs
umount –all unmounts
all public VOBs listed in the VOB registry and all private VOBs owned by
the user.
UNIX Only—Unmounting the View Root Directory
Except on Solaris, if you enter umount –all as root on a platform that supports the operating system command umount –a,
the viewroot directory (/view) is unmounted. To remount
the viewroot directory, you must stop and restart ClearCase.
RESTRICTIONS
