Function performed by unload button How to initiate the function
Force a drive dump (part of the maintenance
mode)
Attention: If the tape drive detects a permanent
error and displays an error code, it automatically
forces a drive dump (also known as a save of the
firmware trace). If you force a drive dump, the
existing dump will be overwritten and data will be
lost. After you force a drive dump, do not turn off
the power to the tape drive or you may lose the
dump data.
If the tape drive is in operating mode (status light is
solid or flashing green), press and hold the unload
button for 10 seconds.
If captured dump data exists, the tape drive places
the data into a dump area.
Reset the drive Press and hold the unload button on the drive for
10 seconds. The drive saves a dump of the current
drive state, and then reboots to allow
communication. Do not cycle power, as it will erase
the contents of the dump.
Single-character display
The drive has a single-character display which displays the characters 0 through U with special moving
characters. The display indicates errors, messages, and diagnostic and maintenance functions.
NOTE:
The single-character display does not indicate the characters B, D, G, I, O, and Z to prevent
misinterpretation as the characters 8, 0, 6, 2 and 1.
Error codes
The drive indicates an error by displaying an error code. The error and informational codes indicated by
the single-character display are set and cleared as indicated in priority (lowest number) displays. The
code numbers are listed in priority order, from highest to lowest. If multiple error conditions occur, the
code with the highest priority (lowest number) displays.
