HP Dynamic Root Disk (DRD) manual Performing administrative tasks on the inactive system image

Page 22

Example 4-1 The drd mount command output

# /opt/drd/bin/drd mount

======= 12/08/06 22:19:31 MST BEGIN Mount Inactive System Image (user=root) (jobid=dlkma1)

*Reading Current System Information

*Locating Inactive System Image

*Mounting Inactive System Image

======= 12/08/06 22:19:52 MST END Mount Inactive System Image succeeded. (user=root) (jobid=dlkma1)

The drd mount command automatically chooses the mount point for the inactive system image. If the image was created by the drd clone command, the mount point is /var/opt/drd/mnts/ sysimage_001. If the clone has been booted, drd mount mounts the original system at the mount point /var/opt/drd/mnts/sysimage_000. To see all mounted file systems, including those in the active and inactive system images, execute the following command:

# /usr/bin/bdf

The output of this command should look similar to Example 4-2, if the drd mount command has been executed:

Example 4-2 The bdf command output

# /usr/bin/bdf

In this output, file systems identified as dev/vg00/* are the active system image file systems. Those identified as /dev/drd00/* are the inactive system image file systems.

4.2 Performing administrative tasks on the inactive system image
