HP XP P9000 RAID Manager Reference Guide (T1610-96061, January 2014)

umount, umountd
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.
Syntax
-x umount[d] drive: [time]
-x umount[d] drive:[\directory] [time] (for Windows 2012/2008/2003/2000)
Argument
DescriptionArgument
Specifies the mounted logical drive.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
2008/2012, it is required to specify 'USE_MOUNTVOL_P' variable to avoid a problem of mount.
[\directory]
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
D: <-> HarddiskVolume8
CAUTION: Umountd has above restriction and it will prompt the delayed IO for dismount, wait
30 seconds until the completion and release the mount point after making dismount status of the
logical drive. This avoids a problem (Windows 2003 only) that the delayed writing for dismount
as Event ID51, 57.
Example
The following example shows the umount subcommand used as an option of the pairsplit command.
pairsplit -x umount F: -x umount G: -g oradb -rw
pairsplit -x mount
Drive FS_name VOL_name Device Partition... Port PathID Targ Lun
C: FAT Null Harddisk0 Partition1... 1 0 0 0
Z: Unknown Unknown CdRom0 ... Unknown
This example unmounts the F: and G: drives, splits all pairs in the specified group (status = PSUS),
enables read/write access to all secondary volumes in the specified group, and then displays all
mounted drives.
Output of the umount subcommand:
Drive: Shows the logical drive recognized by the Windows system
FS_name: Shows the name of the file system formatted on the logical drive
VOL_name: Shows the volume label name for the logical drive
Device, Partition: Shows the device name and partition for the mounted logical drive
Port,Phid,Targ,Lun: Shows the port number, path group ID (bus), target ID, and LUN for the device
adaptor of mounted logical drive.
Note: The umount command flushes (sync) the system buffer of the associated drive before deleting
the drive letter. If umount fails, confirm the following conditions:
