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
logical drive and flushes unwritten data. The umountd subcommand unmounts the logical
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
subc
ommand used as an option of the pairsplit command.
