Unload Button
Function
How to Initiate the Function
Force a drive
memory dump
(part of the
maintenance
mode)
Attention: If the drive detects a permanent error and displays an error code, it automatically forces a drive
memory dump (also known as a save of the firmware trace). If you force a drive memory dump, the
existing memory dump is overwritten and data is lost. After you force a drive memory dump, do not turn
off the power to the drive or you might lose the memory dump data. Choose one of the following
procedures:
If the drive is in maintenance mode (Status LED is solid amber), refer to Function Code 4: Force a
Drive Dump.
If the drive is in operating mode (Status LED is solid or flashing green), press and hold the Unload
Button for ten seconds.
If captured memory dump data exists, the drive places it into a memory dump area.
Reset the drive Press and hold the Unload Button on the drive for ten seconds.
Note: If a tape cartridge is loaded in the drive, it unloads the tape. Repeat the reset procedure after the
tape is unloaded. The drive saves a dump of the current drive state, then reboots to allow communication.
Do not cycle power as this action erases the contents of the memory dump.
Diagnostic and Maintenance Functions
The drive can:
Run diagnostics
Test write and read functions
Test a suspect tape cartridge
Update firmware
Perform other diagnostic and maintenance functions
The drive must be in maintenance mode to perform these functions.
Attention: Maintenance functions cannot be performed concurrently with read or write operations. While in maintenance
mode, the tape drive does not accept SCSI commands from the server.
Note: During normal operation the fan only runs when cooling is required. The fan will be turned on/off during the POST and
Run Drive Diagnostics to demonstrate the fan is operational.
