Example A-1 File system mount points

/var/opt/drd/mnts/sysimage_001

/var/opt/drd/mnts/sysimage_001/var

/var/opt/drd/mnts/sysimage_001/usr

/var/opt/drd/mnts/sysimage_001/tmp

/var/opt/drd/mnts/sysimage_001/stand

/var/opt/drd/mnts/sysimage_001/opt

/var/opt/drd/mnts/sysimage_001/home

If the inactive system image was created by the drd clone command, the mount point for the root file system, chosen automatically by the mount command, is /var/opt/drd/mnts/ sysimage_001. If the currently-booted system was created by the drd clone command, the mount point of the root file system of the original system (now inactive) is /var/opt/drd/mnts/ sysimage_000.

The drd mount command syntax is:

drd mount [-?] [-p] [-q] [-v][-x extended option=value] [-x -?][-X option_file]

Options

-?

Displays the usage message for a DRD command. This option cannot be used with other options.

-p

Sets preview mode. When run with the -poption, a DRD command performs analysis without running the command and reports any errors.

-q

Decreases the verbosity level by one each time it is specified. For example, -qqwill reduce the verbosity from the default value of 4 to 2. If both -x verbosity=5 and -qqqare 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, -vwill increase the effective verbosity from the default value of 4 to 5. If both -x verbosity=1 and -vvare included on the command line, the effective verbosity is 3. The maximum verbosity level is 5. (See also the -x verbosity option.)

-xextended_option=value

Sets the extended option to a value.

-x -?

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

-Xoption_file

Gets the extended options from a file.

Extended options

The following extended options are available:

-x alternate_bootdisk=block_device_special_file

This is the alternate boot disk. The alternate boot disk must be specified as a block device special file.
