Description
Specifies the mounted logical drive.
Specifies the directory mount point on the logical drive. This command option calls "mountvol /P"
internally, if "USE_MOUNTVOL_P" environment variable will be specified. In case of Windows
2008, it is required to specify "USE_MOUNTVOL_P" variable to avoid a problem of mount.
pairsplit -x umount D:\hd1 D:\hd1 <-> HarddiskVolume8 set USE_MOUNTVOL_P=1 pairsplit -x
umount D:\hd2 D:\hd2 <-> HarddiskVolume9
Example for waiting 45 sec:
pairsplit -x umount D: 45
