Release Notes for 1.1.1.110

General Enhancements

Enhanced support for IBM LTO9 Drives. See the section "Library Support of LTO9 Tape Calibration" below.
Improved dual robot initialization:
- If one robot fails any step of the initialization, the failed robot will be pushed out of the way and the library will complete the initialization.
- Robots will be correctly identified in the GUI and logs, even if initialization fails, regardless of whether the database was cleared prior to initialization.
- Improved handling of intermittent single robot failure in a two robot library with PEMs and AEMs.
- Improved handling of robot initialization in a library with only a base after a clear database restart.
- Improved addition, removal, and replacement of robots.
- Since there is no library complex, the rail initialization job will no longer check the state of the library complex and will verify no other initialization jobs are running before initializing the rail.
Added a library resource monitor to collect data on memory usage, load, queue sizes, etc. to aid in diagnosis of library health.
Added support for multiple LOD2 FPGA versions: xc6slx4-2 and xc6slx4-3.
Upgraded the following 3rd party components:
- Apache Log4J to version 2.17.1.
- Apache Mina’s apache-sshd to version 2.8.0.
- org.slf4j to version 1.7.32.
- com.oracle.database.jdbc components to ojdbc8 version 12.2.0.1.
- SNMP4J to version 2.8.8.
Reduced database retention time to 15 days to minimize the size of the tables.
Implemented a system monitor.
Added new security algorithms for SNMP users and trap recipients.

Bug Fixes

Corrected a problem where some drives were not being audited after a Clean Db Restart or door open.
The AEM CAP will now open without multiple button presses.
The lock state of the AEM CAP is now preserved thru the use of the service key, opening then closing the AEM door.
The AEM CAP wait LED will no longer blink if the CAP button is pressed when the AEM door is opened.
If a robot fails during rail initialization, a fault report and associated support bundle will now always be generated.
The sweeping robot will now back off the end stop or other robot to successfully read the frame labels.
Corrected SNMP user recovery so the users are correctly added at boot time.
Corrected several null pointer exceptions that caused communication issues between the library and ACSLS.

Library Support of LTO9 Tape Calibration

When LTO9 media is first loaded into the LTO9 drive, the drive automatically initiates tape calibration, which includes initialization and characterization of the cartridge.

IMPORTANT: IBM has stated that LTO9 calibration may require 20 minutes to 2 hours to complete.

With the 1.1.1.109 code release, the SL4000 library supports longer load times. However, LTO9 tape calibration can well exceed these load times and limited information is available from the library as to the status of this operation. Thus, with the 1.1.1.110 code release, library support has been modified to improve handling of tape calibration, as follows:

Note:

Contact service with any questions, especially with regard to the 1.1.1.109 code release.

Load - When the library checks the status of the drive after a new cartridge is loaded, the library will report that the load is successful if the drive reports that a "calibration" is in process.
Status: To determine if tape calibration is in process, access Drive Properties and select the Details tab. Display Characters: c indicates tape calibration is in process.
Dismount Request: The drive ignores all requests to unload a cartridge while it is calibrating a tape. Thus, if a dismount request is received, the library will fail the request.
Media Validation: Uninitialized cartridges are not currently compatible with Media Validation.
Drive Power Cycle and Library Reboot: When a drive is power cycled while calibrating a tape, tape calibration resumes once drive initialization is complete. A library reboot does not power cycle the drive. Therefore, tape calibration continues during the library reboot.

LTO Drive Firmware Versions

The following LTO drive firmware versions have been verified in the SL4000 library. For the drives to work correctly, ensure the drives are at the minimum versions specified in the table below. Lower drive firmware versions may function, but have not been fully tested with release 1.1.0 or later. For the IBM LTO drives to run in ADI mode, switch 5 must be on.
