Storage Automated Diagnostic Environment Version 2.1
Functions
For each device, the Storage Automated Diagnostic Environment version 2.1
performs the following functions:
1. Sends the information, by way of a discovery event, to the system administrator
through an interface with the transport mechanisms.
Note – The first access to a device yields a discovery event that collects all the
information about that device, plus other events for other preconfigured devices,
that may be generated by health monitors.
2. Reads the proper
/var/adm/messages
files, finds relevant entries, and reports
them as events through the local email notification mechanism, if configured.
3. Connects to Sun StorEdge T3 and T3+ array storage devices directly through in-
band data paths and out-of-band management paths.
4. Reads the device’s configuration and state information, stores it locally in the
cache, compares the results of the last run, and transmits the differences.
5. Reads threshold information and reports errors when the frequency threshold
reaches predefined levels.
