Product Description
Environmental Services
Environmental services circuitry monitors the following elements:
Fan rotation
Power supply output
Power supply status (fan status)
Disk drive status, presence
BCC status
Temperature
Self-test results
Each BCC reports the status of all elements in the disk system, even if the BCC
does not have direct access to the element.
Additionally, the EEPROM on each BCC stores 2 Kbytes of configuration
information and user-defined data, including the manufacturer serial number, and
product number.
Hardware Event Monitoring
A hardware event monitor monitors the disk system and reports changes in
environmental status to Hewlett-Packard’s Event Monitoring System (EMS) for
HP-UX. Hardware event monitoring is an important tool for implementing high
availability. Using hardware event monitors, you can virtually eliminate
undetected hardware failures that interrupt system operation or cause data loss.
The EMS Hardware Monitors Users Guide is available in Adobe
