Resources to Monitor for Root Volumes
In a high availability system, it is recommended that you mirror your root volume, and have them on separate links in separate PVGs. Note that the root volume should always be ACTIVE. Requests to monitor the root volume might look like this:

/vg/vg00/lv/copies/lv01 | when value is... | < | 1 | RETURN |

If one of the root volumes is unavailable, you are alerted and told which one has failed (pv_pvlink/status). If you lose a root disk mirror, you are alerted. You are also notified when the mirror is restored.
