Firmware update files v10 - IBM DLTV4 Tape Drive (39M5659)

Download Description

New IBM xSeries firmware and device driver file naming convention

Changes between V8 and V10.

Key features and fixes in this cumulative set of changes are:

• Stuck Tape Issue: When the tape pack slips on the load, the recovery code enables the electronic motor brake to stop the slip. Previously, the code didn’t disable the brake before continuing.
• Invalid POST Failures: POST failures were being reported in the Disable Data Path POST test due to external events such as SCSI bus reset.
• The tape remaining value being returned by the drive was not correct.
• Enhancement to the load history field log. A temperature field was added.
• Reduced the tape alert for over temp to 54 C instead of 60C.
• Fixed a problem where false POST failures were being reported in the Disable Data Path POST test due to external events such as SCSI bus reset.
• Enhancement for boot performance. We reduced the boot time by doing asynchronous buffer clearing in our hardware.
• Enable check condition reporting on SATA CRC detected errors.
• Enhance Mid tape load process.
• Password handling changes.
• Under specific situations, such as when reading expired media, the Error Correction Code task could become starved for data blocks while performing error corrections.
• Enhancement to drive diagnostic mech test.
• During a load, the drive attempts to determine if the brakes have been released in the cartridge. If the reel does not move 3 hall sensor lengths then the drive will reject the cartridge.
• Decrease the chance of a clean required being sent while a cleaning is being done.
• Enhance abort handling.
• A DLT-V4 drive rejected a valid VS1 cartridge for an incorrect hole pattern.
• Enhance memory test.
• Up read retries by 10 to ensure tension adjust gets through problem tapes.
• Improve the read retry reduced tension value.
• Enable support for second source head.
• Add fix for positioning at end of a track that is not current being used.
• Additional change to deal with bad tach sensors.
• Enhance SATA reset handling.
• Make attributes for Remaining Capacity, Max Capacity, Data Write/Read more accurate.
• If something crazy happens and the VS1 media is ejected while buckled, the drive has the potential to drop the leader.
