Drive Maintenance Test

Drive Maintenance allows you to perform several different drive diagnostic tests.
The drive maintenance tests are only supported for libraries with LTO drives.
Note
To better understand these tests, you need to understand the format of the tape. The tape is divided into
four data sections. Each data section contains 96 tracks (96*4=384 tracks, the number of tracks on a
generation one cartridge). On each edge of the tape (two servo bands), and between the databands (three
servo bands), there are pre-formatted servo bands (five in total). A wrap is defined as a trip from logical BOT
to logical EOT (a round trip would be two wraps).
Each test is described in more detail below.
Run time records the test time in minutes and seconds (m:ss).
Note
Power on self test Runs self diagnostics. This test takes approximately one minute.
(POST)
Fast Read/Write The drive reads and writes two wraps worth of data (a trip down and back) in
each of the four data sections. Ten data patterns are used in this test. No more
than 1.5% of the tape is used. This test takes approximately 25 minutes.
