Updating Drive Firmware

December 2008

Spectra T950 Library

Whenever you update your library firmware, confirm that your drives are 
using the correct firmware version. Check the Tape Drive Firmware and 
Drivers page on Spectra Logic web site at 

 for the currently recommended firmware version and update 

the firmware if necessary.

This section updates information in “Chapter 8 — Best Practices for Using 
the Library” in the Spectra T950 Library User Guide.

To ensure the availability of your library and encrypted data, protect 
library metadata by following the procedures described in this section. 
Library metadata includes library configuration data, the media lifecycle 
management database, and all encryption-key related data.

Metadata is very important in the case of disaster recovery and other 
situations where you need to restore the library. 

Important

Before upgrading drive firmware, make sure that your library is idle and that no 
tapes are loaded in the tape drives. Attempting to update the firmware while the 
library is busy or with tapes in the tape drives may result in failed backup jobs and/
or upgrade failures. If you previously attempted to upgrade drive’s firmware with 
media loaded, unload the tapes, and retry the operation.

Caution

Losing metadata can have catastrophic effects—as can losing keys in any 
encryption key management system, especially when related to encrypted data. If 
you lose all copies of all metadata:
ƒ

Your encrypted data is lost—you will be unable to decrypt encrypted data 
without the encryption keys.

ƒ

You will need to completely reconfigure your library.

ƒ

You will lose stored data about your media that will be time-consuming to 
recover.
