4.13.11 Umount and Umountd Subcommands

The umount subcommand unmounts the specified logical drive and deletes the drive letter.
Before deleting the drive letter, this subcommand executes sync internally for the specified

drive after waiting the delayed IO for dismount. Table 4.44 lists and describes the umount
and umountd subcommand parameters. Figure 4.58 shows an example of the umount
subcommand used as an option of the pairsplit command.
