NAME

drd umount - unmount 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 de-activates 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.

Options

drd umount recognizes the following options:

-? Displays the usage message.

-p Sets preview mode.

-q Decreases the verbosity level by one each time it is speciﬁed. For example,

-qq will reduce the

verbosity from the default value of 4 to 2. If both

-x verbosity=5 and -qqq

are included on

the command line, the effective verbosity is 2. The minimum verbosity level is 0. (See also the

-x verbosity option).

-v Increases the verbosity level by one each time it is speciﬁed. For example,

-v will increase the

effective verbosity from the default value of 4 to 5. If both

-x verbosity=1

and -vv are

included on the command line, the effective verbosity is 3. The maximum verbosity level is 5.

(See also the

-x verbosity option).

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

-x option=value

Sets the extended option to a value. See Extended -x Options deﬁnitions below.

-X option_file

Gets the extended options from a ﬁle.

Extended -x Options

drd umount recognizes the following -x (extended) options:

-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 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.

-x preview=false

Usage: Basic

If true, run this command in preview mode only (i.e., complete the analysis phase and exit; no

changes are committed to disk). Setting this option to true has the same effect as specifying -p on
