Event Notification (HP-UX Systems)
The EMS hardware event monitor polls
environmental services on the BCC and reports any
changes in the status of monitored components.
Depending on how the monitor is set up, you can
receive messages at the console, in e-mail, in a log
file, or through third-party applications. These
messages are likely to be the first indication of a
problem with a disk system.
Events are reported for changes in temperature,
voltage, and the status of replaceable components.
Messages identify five levels of severity:
Critical An event that causes data loss, host system downtime, or
other loss of service. Host system operation will be affected if
the disk system continues to be used without correction.
Immediate action is required.
Serious An event that may cause data loss, host system downtime, or
other loss of service if left uncorrected. Host system and
hardware operation may be adversely affected. The problem
needs repair as soon as possible.
Major Warning An event that could escalate to a serious condition if not
corrected. Host system operation should not be affected and
normal use of the disk system can continue. Repair is needed
but at a convenient time.
Minor Warning An event that will not likely escalate to a severe condition if
left uncorrected. Host system operation will not be
interrupted and normal use of the disk system can continue.
The problem can be repaired when convenient.
Information An event that is expected as part of the normal operation of
the hardware. No action is required.
