Dynamic Logical PARtition Command Line Tool for Integrated Virtualization Manager is a toolkit that enhances the usability of the Dynamic Logical PARtition (DLPAR) feature of systems managed by Integrated Virtualization Manager (IVM).

The DLPAR feature allows processor, memory, and I/O resources of LPAR to be monitored and managed dynamically, without any LPAR instance to be rebooted.

The toolkit consists of the following functions:

• Displays basic system information of IVM
• Displays IVM LPAR's configuration
• Displays I/O Slot status information
• Changes current configuration of IVM LPARs
• Changes I/O Slot configuration
• Backs up configuration of LPARs
• Restores configration of LPARs
• Powers on and powers off LPARs
• Exchanges SSH authorization keys between local and IVM system

The toolkit offers several advantages:

• Performance improvement in time assumption to complete the same task as compared to IVM navigator based GUI-console.
• Flexibility in managing IVM LPARs
• Ability to manage multiple servers at one time
• Complete log mechinism makes it tracing the operation history convenient
• The design's open architecture will enable improvements and new functionality based on user feedback.

How does it work?

Dynamic Logical PARtition Command Line Tool for Integrated Virtualization Manager uses a configuration file for specifying the parameters. It supports UNIX, Linux, Cygwin, and Windows platforms which support bash shell. Please refer to readme.txt in the download package.
