Resolved Issues
Problems resolved in this release of Scalar 1000 641 Firmware are as follows:
Change
Request
Number
Description
25122
SAC 93 errors sometimes occurred on drives while reinitializing the library. To help eliminate
these errors, there is now a 5 second waiting period for IBM LTO drives. If an ACK is not
returned for the drive, there are two retries, resulting in a 15-second total time out. In the
event of a failure, during higher level functions the drive communications error is reported
without additional waiting.
30224
Corrects a condition in which the operator panel and Log_Sense reported the drive’s
firmware level incorrectly because a string variable was not initialized correctly.
30986
Corrects a condition that occurred when printing the log information in the 630 logs, in which
the retract retries was incorrect for previous versions.
33963
Media settings are now preserved during a firmware upgrade. (When upgrading from 630 to
640 firmware, if the media mode was set to extended it was reset to default mode after the
upgrade.)
36097
Corrects a condition in autocleaning immediate mode in which an expired AIT cleaning tape
resulted in move failure.The library now recognizes an expired AIT cleaning cartridge and
marks it expired in the database. Additional functionality has been added to force a cleaning
event on AIT 3 drives when necessary.
37030
Corrects a condition that caused a SAC 7A Reach Homing Error.
38272
Current scan velocity and cleaning cartridge information is now included in the library log.
38796
Corrects a condition that prevented toggling element addressing between old and new
styles for ADSM.
39285
The library log no longer fills with meaningless errors when the library has no RMU installed.
Only one message is generated when no RMU is installed.
39948
Corrects a condition for AIT and SDLT drives that caused SAC 7C errors due to drive
recovery functionality implemented in the 640 code.
40727
Total wait time for AIT drives is increased to 15 seconds to reduce the occurrence of SAC 93
errors. Initial wait time is now 5 seconds. If there is no response, the entire command
sequence is retried two more times, providing 15 seconds total time before reporting a drive
communication failure.
42786
Systems with LTO drives now have a longer wait time to ensure that the power-on self test
(POST) completes. This longer wait time eliminates SAC 96 errors that occurred on some
libraries when auto inventory was turned off, which resulted in shorter wait times that
prevented the POST from completing.
42795
Corrects a condition in which the SDLT get profile was incorrect, which caused SAC 7C
errors.
