The Magnetic Tape Media Reliability Report provides a concise
report of the tape volumes that have encountered permanent or
temporary errors during a selected current period and a
previous period of time. The objective of the report is to
highlight the tape media failures that have occurred and that
some corrective action can be taken.
The following information is provided in the Magnetic Tape
Media Reliability Report:
VOLUME SERIAL - the six-character volume serial number
for the magnetic tape volume
NO. OF MOUNTS - the number of times the volume was
mounted during the selected current period of time
SIO COUNT - the number of Start I/O operations issued to
the volume.
PERMANENT ERRORS - the number of permanent read and
write errors during the current period. Any
permanent failure indicates that an unrecoverable
error has occurred. The volume could be bent or
crimped or the oxide surface could be worn.
The following information appears for the current period and
a specified previous period:
TEMPORARY ERRORS - the number of temporary read and
write errors during the period. Only temporary
errors that are not associated with permanent
errors are shown. If a number of temporary errors
occurred, followed by a permanent error, only the
permanent error will be counted.
SIO CT/TEMP ERR - the ratio of the Start I/O count to
the total number of temporary read and write errors
for the period. A small number for the ratio of
SIO operations to temporary errors is generally an
indication of a media problem.
