NAME
drd-umount: drd - umount mode unmounts the inactive system image
SYNOPSIS
drd umount
[-?][-p][-q]... [-v]... [
-x option=value]... [-x -?][-X
option_file]
DESCRIPTION
The
drd umount command unmounts all the file systems in the inactive system image.
The root file system of the inactive system image is expected to be mounted at either
/var/opt/drd/mnts/sysimage_000
or /var/opt/drd/mnts/sysimage_001
.
If the inactive image contains an LVM volume group, the
drd umount command then deactivates and
exports the volume group from the system.
If the inactive image contains a VxVM disk group, the
drd umount command then issues vxvol sto-
pall
but does not deport the disk group. This ensures that the inactive image remains bootable.
Note: Before running drd umount, all processes (including shells and editing sessions) must change
directories to a file system outside of the inactive system image or be terminated. Otherwise, drd
umount
will fail with a Device busy error.

drd umount recognizes the following options:
-? Displays the usage message.
-p Sets preview mode. See also -x preview, in the Extended -x Options section below.

-v Increases the verbosity level by one each time it is specified. For the interaction with

-x -? Displays the list of possible -x (extended) options.
-x option=value

example of an option file.
Extended -x Options
drd umount recognizes the following -x (extended) options. If a default value exists, it is shown in
bold.
-x logfile=/var/opt/drd/drd.log
Usage: Basic
This is the path to the log file for this command. Each time DRD is run, this file will grow
larger. This can be changed, for example, to a month-specific location for easier archiving,
off-host backup, and rotation.
-x log_verbosity=4
Usage: Basic
Specifies the level of message verbosity in the log file. (See also -x verbosity .) Legal
values are:
0 Saves only ERROR messages and the starting/ending BANNER messages.
1 Adds WARNING messages.
2 Adds NOTE messages.
3 Adds INFO messages (informational messages preceded by the * character).
4 Adds verbose INFO messages.
5 Adds very-verbose INFO messages.
