SCD dot

If a drive dump is present while the drive is in maintenance mode, a single red dot illuminates in the lower right corner of the SCD. To download the drive dump, see Locating Management functions or IBM Tape Diagnostic tool (ITDT).

The SCD dot turns OFF when you obtain a dump or update the drive firmware.

Note: If the drive dump is stored in ROM memory (SCD dot ON solid), the dump is lost when you turn OFF the power or reset the drive.
