Table 11 Log Field Descriptions
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. 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 with no
interruptions.
Power cycles (PC) is how many times the
drive has experienced a POC. Each time a
drive logs a Hard Event, it will increment this
count as well.
