IBM periodically releases firmware updates that are intended to, 
among other things, support new features, increase overall reliability, 
improve tape handling, further reduce any possibility of data loss/data error, 
and provide continued enhancements to diagnostic capabilities. 

The readme files contain information that may not be included in the IBM Diamondback Tape Library documentation. 
The readme files take precedence over the documentation.  
Therefore, any information in this file that conflicts with information 
in the documentation will supersede the IBM Diamondback Tape Library documentation

The IBM Diamondback Tape Library is responsible for providing basic and advanced tape 
functionality for backup/restore and archive environments. For more details on 
functionality and other operation procedures consult the IBM Diamondback Tape Library documentation 
available for viewing at the following link: 

https://www.ibm.com/docs/en/diamondback/2.9.2

In order to provide maximum performance and reliability, it is recommended that the recommended version of 
microcode is installed on your IBM tape libraries and tape devices. These firmware updates are intended 
to, among other things, increase overall reliability, improve tape handling, further reduce any possibility 
of data errors and provide continued enhancements to diagnostic capabilities.


CODE LEVEL RECOMMENDATIONS:
Current Diamondback firmware level recommendations are available at https://www.ibm.com/support/pages/ibm-diamondback-code-update-recommendation

The IBM Diamondback Tape Library follows the IBM Product Security Incident Response Team (PSIRT) process to comprehensively address security vulnerabilities in IBM products. Review the process description and view or subcribe to IBM security bulletins in the following link:

SUPPORTED OPERATING SYSTEMS:

For details on supported tape attachment please refer to the System Storage Interoperation Center website.

TROUBLESHOOTING:
IBM Tape Diagnostic Tool (ITDT) provides the customer with functionality 
to perform maintenance tasks and run diagnostic tasks to determine tape 
device issues.  This is available to download with the device driver.

Support:

        Support for the following ITDT version:
	* ITDT-SE v9.6.1.20230511	(See ITDT limitations under Known Issues and Limitations section)
    	* ITDT-GE v9.6.0.20230215	(See ITDT limitations under Known Issues and Limitations section)


Known Issues and Limitations:

- Brocade: Brocade HBAs, and their IBM version, do NOT support L-port topology. Direct attach configurations to our Tape Storage products is therefore NOT supported with these cards.
- Brocade: Brocade HBA driver on Linux has to be installed manually by user, as it is not native on the operating system
- ITDT: For a complete list of ITDT Limitations and Known Issues, please refer to the Readme file and the "Device Driver Installation and User Guide" distributed with the software.
