TS3400 Tape Library Maintenance Information
Methods of Updating Firmware
Important: When updating firmware, ensure all host applications are varied offline.
Do not power-off the drive until the update is complete. The EEPROM in
the Library Control Blade has a library firmware backup region. If a
library firmware download fails due to power shutdown or other action,
the backup firmware is restored automatically.
Periodically visit the web at http://www-03.ibm.com/servers/storage/support/
index.html for updated levels of firmware.
