Ultrium 230 external firmware (E22D)

[Brian_130]

Can someone tell me what the improvements are over the previous firmware?

HP Library & Tape Tools (the diagnostic tool) often provides a summary of changes for each firmware revision. On the 'get files from web' function, there is a 'detail' button which lists the firmware changes.

Fixed between E15D and E22D:

BugFix:
Allow write from BOT (beginning of tape) on cartridges with cartridge memory corruption (CRC errors only). When not writing from BOT drive will report cartridge as write protected

Enchancement:
Additional MAM ID field information stored

Enchancement:
Support for Universal Cleaning Cartridge (UCC)

Enchancement:
Prevent drive failure if eject button is depressed during a non immediate command

Enchancement:
Improved cartridge memory update algorithm

Enchancement:
Change to ???snapped tape??? handling. If a cartridge is loaded with the leader pin missing and the drive is power cycled, it will be possible to eject the damaged cartridge

Enchancement:
Improved space and locate command performance

Enchancement:
Improved performance and tape handling during stream fail conditions

Enchancement:
Improved retry algorithm when handling off track events

Enchancement:
Improved eject time

Enchancement:
Improved performance in variable mode with variable record lengths

Enchancement:
Improved handling of multiple bus resets which previously would have caused the drive to ???fall off??? the bus

The diagnostics software HP Library & Tape Tools can be used to display revision history.

Start L&TT, go to the 'Get Files From Web' function, select 'show all firmware' for 'all supported devices' - scroll to the E22D firmware, click on it to highlight it (don't worry about the check box), and then click the 'Details' button. That should show the change history of that firmware file.

L&TT can be downloaded at http://www.hp.com/support/tapetools.
