Database objects. See Section B.2.4.1, “Converting SLS/MDMS V2.x Symbols and Database
Files to ABS/MDMS V4.x” for more information.
• Possible conflicts that can occur during the conversion and the methods to resolve the conflicts.
See Section B.2.4.1.3, “Resolving Conflicts during the Conversion” for more information.
• Prev3 Support for using SLS as the client to view the backed up data after the conversion.
See Appendix C, “Applying Prev3 Support” for more information.
• Conversion of SLS SBK Symbols to ABS Policy objects. SLS SBK Symbols are converted
into the following ABS Policy objects: Storage, Environment and Save objects. See Section
B.2.4.3, “Converting SLS SBK Symbols to ABS Policy Objects” for more information.
• Evaluation of the DCL command procedures that are created as part of the SLS SBK Symbols
to ABS Policy objects conversion. See Section B.2.4.3.4, “Evaluating the ABS DCL
Command Procedures” for more information.
• Consolidation and implemention of ABS Policy objects for better performance. See Section
B.2.4.3.5, “Consolidating ABS Policy Objects” and Section B.2.4.3.6, “Implementing the
ABS Policies” for more information.
• Disabling SBK files and monitoring ABS activity after the conversion. See Section
B.2.4.3.9, “Disabling the SLS SBK Files” and Section B.2.4.3.11, “Monitoring ABS Activity”
for more information.
• In case you want to revert to the SLS/MDMS V2.x environment, you can use the
ABS/MDMS V4.x to SLS/MDMS V2.x conversion procedure. (Only the volume database
is converted back to the MDMS V2.x environment.) See Section B.2.6, “Converting MDMS
V4.x to a V2.x Volume Database” for more information.
B.2.1 Why Convert from SLS/MDMS V2.x to ABS/MDMS V4.x?
B.2.1.1
Storage Library System backup (SLS), a legacy product of HP, has been in existence since the
late 1980's and has served the OpenVMS customer base extremely well. With the decision to
make ABS/MDMS the default choice as the Backup application on OpenVMS operating system
environments, the need has risen to provide guidance to those wanting to migrate from SLS systems
to ABS/MDMS systems.
Advantages of using ABS
• Support for Windows 2000 and UNIX clients
• Support on I64 for ABS/MDMS
• Consolidated Policy Management
• More intuitive policy organization, with Shared Policies
• Automation of the backup process using MDMS scheduling objects, with minimal user
intervention
• Better Logging and Diagnostic capabilities
• Automatic Full and Incremental operations
• More versatile user requested operations
• On Disk Backups
• A sophisticated and reliable Media Management subsystem
• Better user interface using OPCOMs and Mail Notifications
