Field Description
Event Log Number A sequence number that indicates the order in which the event was
logged.
Event Number or
Name
This field appears in every event log, but varies depending on the
event type. This field indicates the type of log.
POH/PC The tracking information for how many power-on-hours (POH) the
drive has had since it was shipped from Quantum. This is how many
hours the drive has had power applied regardless of the number of
times it is turned on and off. POH is updated once every 60 minutes
the drive has had power applied to the drive with no interruptions.
Power cycles (PC) is how many times the drive has experienced a
power on cycle. Each time a drive logs a Hard Event, it will increment
this count as well.
Note: This event type only indicates each time the test ran and
experienced the error condition.
