Emergency recovery with an encapsulated or mirrored root disk

There are three phases to performing an emergency recovery with an encapsulated or mirrored root disk:

1. ``Creating the Emergency Recovery boot media and tapes''

2. ``Bringing the system back after emergency media is created''

3. ``Performing recovery when the primary and mirrored root disks fail''

During the following process, use the vxprint(1M) command to obtain information about the encapsulated root disk and the disk to which it is mirrored. In this example, an initial install was done with all additional filesystems created, and mirrored onto another disk. Your installation may differ, so you may have a different number of partitions on the root disk. This procedure is valid for recovering from a disaster where the primary and mirror disks both fail, and ODM was used only to encapsulate the root disk and mirror it. Information on any other ODM disks should be saved so that they may later be restored.
