Dynamic Root Disk and MirrorDisk/UX

2. Clone the booted system to the newly available mirror disk. If desired, use drd runcmd to

patch the clone.

3. Boot the clone.

4. Mirror the newly booted system, using the steps described above in How to Mirror vg00 – HP

9000 System for PA-RISC systems (or How to Mirror vg00 – HP Integrity System for 11iv2

Integrity systems or 11iv3 systems). Although DRD may be notified of the new mirror by calling

drd_register_mirror mirror_disk, it is not required. There is no other disk to boot, so

drd activate and subsequent drd mount commands need not be considered.

In this case, no DRD commands are useful after the scenario is completed, because the clone has

been overwritten by the mirror. However, the clone procedure may be repeated when new patches

need to be installed.
