HP Dynamic Root Disk (DRD) specification

Example 6-3 Using drd deactivate after activating — agile DSF

In this example, drd activate is executed on a system without performing a reboot, followed by running drd deactivate, and the end result is no change. For example, if you have a system with the root volume group on /dev/disk/disk11 and a clone created on /dev/disk/disk10, the output of drd status is:

# drd status

======= 07/01/08 13:20:04 MDT BEGIN Displaying DRD Clone Image Information (user=root) (jobid=drdtest1)

* Clone Disk:	/dev/disk/disk10
* Clone LIF Area:	AUTO file present, Boot loader present
* Clone Creation Date:	07/01/08 09:37:58 MDT
* Clone Mirror Disk:	None
* Mirror LIF Area:	None
* Original Disk:	/dev/disk/disk11
* Original LIF Area:	AUTO file present, Boot loader present
* Booted Disk:	Original Disk (/dev/disk/disk11)
* Activated Disk:	Original Disk (/dev/disk/disk11)
======= 07/01/08 13:20:10 MDT	END Displaying DRD Clone Image Information
succeeded. (user=root)	(jobid=drdtest1)

If you use drd activate and do not perform a reboot, and then use drd deactivate, the output of drd status is:

# drd status

======= 07/01/08 13:20:04 MDT BEGIN Displaying DRD Clone Image Information (user=root) (jobid=drdtest1)

* Clone Disk:	/dev/disk/disk10
* Clone LIF Area:	AUTO file present, Boot loader present
* Clone Creation Date:	07/01/08 09:37:58 MDT
* Clone Mirror Disk:	None
* Mirror LIF Area:	None
* Original Disk:	/dev/disk/disk11
* Original LIF Area:	AUTO file present, Boot loader present
* Booted Disk:	Original Disk (/dev/disk/disk11)
* Activated Disk:	Original Disk (/dev/disk/disk11)
======= 07/01/08 13:20:10 MDT	END Displaying DRD Clone Image Information
succeeded. (user=root)	(jobid=drdtest1)
