•
A drop of margin over time—Rapid drops can indicate contamination.
•
Tapes nearing the end of their working life—Older tapes are less reliable and may need to
be replaced.
•
Drives nearing the end of their normal working life—This is unlikely because the estimated
lifespan of HP drives is very high.
Device-specific report analysis
This section explains device-specific report data. Currently, the report format is only available for
LTO drives and media. As support for the report format is added to other devices, the information
will be added to this section.
LTO drives
The report groups information into the following standardized sections, and wherever possible,
identifies the drive and media as separate devices.

Identity
This section shows the identification of both the drive and the interfaces. The Format entry also
indicates compatibility.
Health
This section is split into two main sections: Device Analysis and Write/Read margin data.
•
The Device Analysis section shows the output of the device rules. This is the first place to look
for health information and advice on corrective action.
•
The Write/Read margin data section shows the write and read margin of the last five tapes
(current and previous four tapes).
◦ The summary line (top line of this section) shows the average and worst margin values
found in the available history. The Current tape and four Previous tape lines show margin
information for the last five tapes used. If there is a margin warning for one tape, then
that suggests a suspect tape. Cross check with the cartridge history below or try the tape
in another drive. If there is a margin warning for all tapes then the drive itself is suspect.
Try cleaning the drive and run the Drive Assessment test to check the drive.
◦ The Head life, Reposition life, and Load/unload life lines show life figures for the drive.
Configuration
This section shows configuration information for the drive and its associated interface controller.
•
In the Drive section, useful configuration information is listed which can assist with
troubleshooting potential drive problems. For example, the report records the current data
