HP Dynamic Root Disk (DRD) manual Activating the inactive system image

Page 36

TIP: If you have already booted the (previously) inactive image, you can use drd activate to return to the (previously) active image.

Example 6-2 Using drd deactivate after activating — legacy DSF

In this example, /dev/dsk/c2t3d0 contains your root volume group, and you use drd clone to create an inactive system disk at /dev/dsk/c1t2d0. Next, you execute drd activate. The results are:

•Disk set to become the active system disk after the next reboot: /dev/dsk/c1t2d0

•Disk set to become the inactive system disk after the next reboot: /dev/dsk/c2t3d0

The output of drd status is:

# /opt/drd/bin/drd status

======= 07/01/08 13:14:36 MDT BEGIN Displaying DRD Clone Image Information (user=root) (jobid=drdtest1)

succeeded. (user=root)	(jobid=drdtest1)

If plans change prior to rebooting the system and you do not want to have /dev/dsk/c1t2d0 become the active system disk, you can use drd deactivate to “undo” the previous drd activate command.

The results are:

•Disk set to become the active system disk after the next reboot: /dev/dsk/c2t3d0

•Disk set to become the inactive system disk after the next reboot: /dev/dsk/c1t2d0

The output of drd status is:

# drd status
