HP StorageWorks LTO-4 Ultrium 1840 SCSI Tape Drives firmware revision B63D release notes (EH853-90939, June 2011)

New functionality
• To improve drive reliability, an additional calibration may be done when loading
a tape to account for variations in media. Load times will increase a) to test whether
calibration is required and b) to perform calibration, if invoked.
Enhancements
• Drive tuning change for better reading capability on some tapes written by non-HP
drives
• Use of adjacent channel information during Spacing/Locating to prevent 5090/5092
Errors
• Error rate counters are now cleared on a load instead of being cumulative since
power-on
Fixes
• Fixed rare issue where a Write attribute command could cause datasets to be written
beyond the End of Wrap turnaround point (EOW)
• Fixed an issue where deltas could be observed between the power-on times reported
in different L&TT logs and the drive logs
• Fixed a rare issue that could cause very poor performance
• Fixed an issue on the previous release (B62D, which was withdrawn from the web)
that could cause a Space/Locate command on an uninitialized tape to fail
