HP Dynamic Root Disk (DRD) manual # /opt/drd/bin/drd activate

Page 34

# /opt/drd/bin/drd activate

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

# /usr/sbin/setboot -v

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.
