HP Command View for Tape Libraries Software - Manual (Page 60)

The TapeAssure drive health tab lists:
•
Serial Number—The serial number of the drive. This is a static value and will change if a drive
has been replaced. Use the serial number when contacting HP support.
•
Overall Health – An Overall Health icon and a details link allow you to view the Drive Health
and Life graphs and tabular data.
•
Drive Type—The drive type including generation and interface type.
•
Library Serial Number—The HP serial number that uniquely identifies the library. Defined at
manufacture, this is the number to quote when contacting HP support.
•
Write Quality—A measure of the amount of tape used to write high quality data to the last
loaded tape followed by the amount of data written to the tape since it was last loaded.
Even if the warning is reported, the data will still have been written at high quality (unless the
drive reported an error) though more tape was used than recommended by HP. Note that a
warning will normally trigger an alert.
If appropriate, maintenance recommendations are made, such as to clean the drive and/or
replace the tape.
•
Read Quality—A measure of the ease with which data was read back from the most recently
loaded tape followed by the amount of data read from the tape since it was last loaded.
Even if the warning is given, the data will have been read back correctly (unless the drive
reported an error) though more error correction was required than recommended. Note that
a warning will normally trigger an alert
If appropriate, maintenance recommendations are made, such as to clean the drive and/or
replace the tape.
•
Head Life (% Life Remaining)—The percentage of remaining head life based on the amount
of tape passed over the head compared with worst case life expectancy testing in a clean
environment.
If a life warning is shown, the drive should be replaced at the next maintenance period.
•
Reposition Life (% Life Remaining)—The percentage of remaining reposition life based on the
number of changes in direction of the tape over the life of the drive compared with the worst
case life expectancy in a clean environment.
If a life warning is shown, the drive should be replaced at the next maintenance period.
