•-xTurns on SCSI debugging.

•-jDirects the medialist command to jukebox ID rather than the default of 1.

•Network Attached Libraries—Enhancements to the network attached library interface include:

•Reducing the number of 'query drive' commands thus softening the load on the XDI interface. A function to test the need to inquire about library drive status is added. If there are no drive candidates to service a pending IO request, the library query drive command is not called. This will reduce the load on the network library interface.

•Releasing the shared memory semaphore across the library query drive command. Failure to do this will cause the entire AMASS system to lock up should a query drive command fail to complete (is hung).

•Adding a feature that will time out a hung XDI command. This happens frequently in the presence of library errors.

•Adding XDI failed mount/dismount retry option. XDI failed mounts and dismounts are retried 3 times before a drive/volume are taken out of service.

The combination of these four fixes will prevent AMASS from locking up and loosing drive/volume resource in the presence of library errors.

This new functionality is controlled by using the following environmental variables:

•AMASS_DISABLE_TEST_DRIVE - should the reduction in queries to the drive cause undesired effects, this environmental variable will return AMASS to pre-fix default state that continually pings the library interface.

•AMASS_DRIVESTAT_TIMEOUT=<new_val_in_seconds> - changes query drive time out from the default of 10 seconds to the value specified here.

•AMASS_STORE_TIMEOUT=<new_val_in_seconds> - changes the library mount/dismount timeout from a default 360 seconds to the value specified here.

•AMASS_DISABLE_LIBTIMEOUT - should the library timeout feature cause undesired effects, this environment variable will disable the feature.

Note

These environmental variables can be set in the shell in which AMASS is

started or put directly in the amass_start script.

 

•vgimport—Importing and exporting large volume groups is expedited with the -qoption.

Usage: vgimport [-yun] [-p path] [-v volumenumber(s) -or- -f volume_list_file] filename; where:

•-q quick; Do not verify NSR label against volume.

•-ySuppress questions and informational messages.

•-uPrints this usage message.

•-nParses the metadata file, but does not update the database.

•-p path Specifies volume group root directory name.

•-v volumenumber Specifies import volume number(s) (# #,# #-#).

•-f volume_list_file Obtains volumes from input file (one volume per file line).

•volstat—New command line options have been added to this tool. The volstat command options now include:

Usage: volstat [-aifFsuy] <volume-number>; where:

• -aChanges volume status to active.

5.4 specifications

ADIC 5.4 is the latest iteration of the Advanced Data Integrity Checker (ADIC), designed to bolster data security and ensure reliability in digital ecosystems. This version introduces a host of features and technologies that enhance the robustness of data management systems across various industries.

One of the most significant features of ADIC 5.4 is its advanced error detection and correction capabilities. Utilizing sophisticated algorithms, this tool can identify discrepancies in data integrity caused by corruption, unexpected changes, or malicious tampering. By promptly flagging these issues, ADIC minimizes the risk of data loss and ensures that organizations can maintain high standards of reliability.

Another key characteristic of ADIC 5.4 is its integration with Artificial Intelligence (AI) and Machine Learning (ML). These technologies allow the system to learn from previous data patterns, improving its detection and correction efficiency over time. By leveraging AI, ADIC can predict potential vulnerabilities, providing organizations with actionable insights to preemptively address data risks.

ADIC 5.4 also boasts enhanced compatibility with cloud-based environments. As more businesses migrate to the cloud, the need for tools that can seamlessly integrate and secure data stored in decentralized locations becomes critical. ADIC 5.4’s multi-platform support ensures that users can validate data integrity, regardless of where it resides, whether in on-premises systems or across multiple cloud providers.

Furthermore, the user interface has been revamped for better usability, featuring intuitive dashboards that present complex data insights in an easily digestible format. This allows users of varying expertise levels to navigate the system efficiently, promoting quick decision-making in critical situations.

The implementation of real-time monitoring within ADIC 5.4 is another noteworthy characteristic. This enables organizations to receive immediate alerts on data integrity issues, allowing for swift remediation actions. The system’s ability to generate comprehensive reports aids in compliance with regulations and internal policies, supporting organizations in maintaining transparency and accountability.

In summary, ADIC 5.4 represents a pivotal advancement in data integrity verification technologies. With its powerful error detection, AI integration, cloud compatibility, improved user interface, and real-time monitoring capabilities, it provides organizations with the tools necessary to safeguard their data assets effectively. As data security remains a paramount concern, solutions like ADIC 5.4 are essential for maintaining trust and efficiency in digital operations.
