Preparing the Inactive System Image to Activate Later

If you do not want to make the inactive system image the active system image right away, you can configure the drd activate command so that it does not reboot the system. Because -x reboot=false is the default, the command is simply:

If you are not certain which system image is set to become the active system image when the system boots, execute the following command:

For additional information, see the setboot(1M) manpage.

In the following example on an HP-UX 11i v2 system, a system administrator uses /stand/bootconf, setboot, and ioscan to determine that, currently, the primary boot disk (the one that will be booted on the next reboot) is the same as the currently booted disk. The system administrator is ready to boot to the clone, but wants to set the alternate boot disk to the current boot disk. (In the event of any problem booting the clone, the system will then fall back to booting the alternate, current disk.)

The system administrator issues the drd activate command shown below, then uses setboot to verify the settings.

	NOTE: The following example does not correspond to any of the figures in this guide.

The drd activate and drd deactivate commands enable you to choose an image to be booted the next time the system is restarted. An image is considered to be activated if it will be booted at the next restart of the system. Executing the drd activate command activates the inactive system image. Executing the drd deactivate command activates the booted image.
