The Equipment Reliability Summary Report provides an overview
of hardware reliability by device class and device type for
the current period and a specified previous period of time.
The objective of the report is to provide comparison counts
and statistics for the hardware attached to the system for a
current period and a previous period of time. The comparison
provides a starting point for further analysis of the
equipment reliability.
The comparison provides a usage count (for example, SIO
operations and seeks) a permanent and temporary error count,
and the ratio of the usage count to the number of permanent
and temporary errors for the current period and a specified
previous period of time.
In reviewing the Equipment Reliability Summary Report, the
error ratios can be used as an indication of how well the
equipment is performing. In general, a small ratio indicates
that the equipment is not performing well. If the ratio for
the current period is less than the ratio for the previous
period, you can assume that the error rate is increasing for
the devices.
If the reliability figures indicate a problem or potential
problem, the device reliability trend report can be used to
help pinpoint the device or devices that are failing.
The following information is provided in the Equipment
Reliability Summary Report:
DEVICE CLASS - the equipment hardware class, for
example, magnetic tape or direct access
DEVICE TYPE - the type of equipment within the class,
for example, 3330 or 3350 devices within direct
access
The following information appears for the current period and
a specified previous period:
USAGE COUNT - a measure of usage for the device type.
In general, this will be number of Input/Output
operations (SIOs). For direct access devices, the
count will be the number of seek operations.
PERMANENT ERRORS - the number of unrecoverable errors
that occurred
TEMPORARY ERRORS - the number of recoverable or
correctable errors that occurred
RATIO OF xxx - the ratio of device usage to permanent or
temporary errors.
