Hardware Log Sensor Messages
Hardware logs provide hardware status messages to systems management software. On certain systems,
the hardware log is implemented as a circular queue. When the log becomes full, the oldest status
messages are overwritten when new status messages are logged. On some systems, the log is not circular.
On these systems, when the log becomes full, subsequent hardware status messages are lost. Hardware
log sensor messages listed in
Ta ble 2-12 provide status and warning information about the noncircular
logs that may fill up, resulting in lost status messages.
1503 AC power has been lost
