Managing TrustLevel
...
- NCMP is checking every DMI Plugin for health at interface 1 every 30 seconds using the Health Status Trust Level DMI Map
- IF a DMI Plugin goes down, that DMI Plugin's health status is updated to DOWN NONE in the Health Status Trust Level DMI Map
- The CM handles corresponding to DMI should be set to NONE.
- IF a DMI Plugin comes back up, Heath status is set back to UP COMPLETE for that DMI plugin only.
