IBM T400F manual Exiting Maintenance Mode, Updating the Firmware

Exiting Maintenance Mode

To manually exit maintenance mode, press the unload button once per second until

0appears on the single-character display. Press and hold the unload button for 3 seconds. The drive exits maintenance mode (the solid amber status light becomes solid green, then turns off).

You can also exit maintenance mode by pressing the unload button during any maintenance or diagnostic function.

Updating the Firmware

Attention: When updating firmware, do not power-off the tape drive until the update is complete, or the firmware may be lost.

Periodically check for updated levels of drive firmware by visiting the web at

http://www.ibm.com/storage/lto. You can update your drive’s firmware by:

vObtaining the new firmware image and downloading it to the drive through the SCSI or Fibre Channel interface

vObtaining the new firmware image and downloading it to the drive through the LDI or RS-422 interface

vLoading the firmware from a field microcode replacement (FMR) tape cartridge

For instructions about how to obtain a new firmware image or FMR tape, visit the preceding web site. To update the firmware, refer to the following sections.

Updating Firmware through the SCSI or Fibre Channel Interface

Attention: SCSI drives and Fibre Channel drives require different firmware images.

When you update the tape drive’s firmware by using the SCSI or Fibre Channel interface, the procedure varies, depending on whether your server uses an IBM tape device driver or a non-IBM tape device driver (such as a driver from Sun, Hewlett-Packard, or Microsoft).

For instructions about updating firmware from a server that uses an IBM tape device driver, refer to the IBM Ultrium Device Drivers Installation and User’s Guide.

To update firmware from a server that uses a non-IBM tape device driver, refer to the documentation for that device driver.

Updating Firmware through the Library/Drive Interface

The Ultrium 2 Tape Drive includes a firmware update feature that allows a tape library to download firmware to the drive by using the Library/Drive Interface (LDI) while the drive performs normal host operations on logical unit number (LUN) 0 of the SCSI Protocol Interface. The update typically takes 63 seconds and a maximum of 140 seconds. To activate the new firmware, cycle power to the drive, or unload the drive and issue a Power-on Reset command. The command may be received by the SCSI interface or the LDI (RS-422) interface.

Note: If a Power-on Reset command is received while a cartridge is loaded in the drive, the drive will respond with a Check Condition. It will not activate the new code level until you cycle power, or until you receive a Power-on Reset command when the drive does not contain a cartridge.
