B-3
DMI
Adaptec CI
At startup time the CI gathers information about Adaptec RAID
controllers and stores this information in a DMI format table. When
an inquiry is made for a particular attribute it is obtained from this
table for static information or through the engine for dynamic
information.
The Adaptec CI sends event notification up to the SP for events
that are reported by the broadcaster module. These events include
high or low voltage, high temperature, drive failure, and RAID
status changes.
Figure shows how DMI relates to other elements in the system
when an RAID controller is present.
