Description

Item

the volume of data needed to completely fill a tape). If
a life warning is shown, the cartridge should be retired
at the next maintenance period. HP recommends HP
media for increased load/unload life.

An estimate of the percentage of remaining read/write
life of the cartridge. Based on the amount of tape pulled
over drive heads compared with HP recommended tape
life (normally expressed in terms of full volume
equivalents
,which is the volume of data needed to
completely fill a tape). When this figure reaches 0%,
the cartridge should be retired.

An assessment of whether the cartridge load/unload
life remaining is within specification followed by an
estimate of the remaining load/unload life.

Load/Unload Life

Based on the number of load/unload cycles compared
with HP recommendation. If a life warning is shown,
the cartridge should be retired at the next maintenance
period. HP recommends HP media for increased
load/unload life.

An estimate of the percentage or remaining load/unload
life of the cartridge based on the number of
loads/unloads compared with HP recommendation.
When this figure reaches 0%, the cartridge should be
retired.

Usage

The maximum capacity of the tape.

Native Capacity

The amount of data stored on the tape.

Native Capacity Used

The capacity remaining on the tape after the exclusion
of the used capacity.

Native Capacity Remaining

The total tape pulled expressed in terms of the equivalent
number of full-volume writes or reads.

Total Tape Pulled

The number of load and unload operations the drive
has performed over the life of the drive.

Load/Unloads

Temperature

The maximum operational temperature of the sensor
located on the controller board of the drive the tape

Maximum internal drive temperature

was loaded in followed by an assessment of whether
this temperature is within specification.

The temperature value will be significantly higher than
ambient temperature but dependent on it, as well as on
drive usage and air flow. The algorithm that assesses
whether the drive is in specification takes account of the
location of the sensor and uses that to estimate the
thermal conditions of the tape path. A warning reported
here should be considered as a warning that the
temperature of the tape path has exceeded
recommended limits and the airflow of the drive should
be investigated.

If a warning is shown, the airflow for the drive should
be improved. If this cannot be corrected, contact HP
support. Note that a warning will normally trigger an
alert for the drive at the time so the alert log can be
checked to identify the drive.
