Overview BlueScale Drive Lifecycle Management (DLM) lets you monitor
the DLM health information of each drive in the library and helps you
identify drives that experience a high number of errors or other problems
during operation. See Chapter 10 – Using Drive Lifecycle Management,
beginning on page 290 for detailed information about using DLM to
monitor the health of drives.
If you suspect that a drive is experiencing problems or if the Drive
Lifecycle Management report indicates that a drive is experiencing
repeated errors, you can use the DLM Drive Health Verification wizard to
test the drive. This test, when used in conjunction with other DLM data
and MLM data, can help you determine whether a drive or the media is the
source of the errors you are investigating.
