Abstract: A method is used in managing command line interface commands. Legacy CLI command information is received at a command line interface (CLI) provider. At the CLI provider, it is determined to convert the legacy CLI command information. The CLI provider has an adapter for performing the conversion. Updated CLI command information is derived by the adapter from the legacy CLI command information. The updated CLI command information is submitted to a plugin for processing.

Abstract: A method is provided for testing a feature provider module of a data storage management application (DSMA), the feature provider module providing a feature. The method includes (a) receiving, at a simulation module of the DSMA when the DSMA is not in communication with an external feature implementation component, a test feature command from the feature provider module, (b) at the simulation module, simulating behavior of an interface module in communication with the external feature implementation component, and (c) at the simulation module, returning a feature response to the feature provider module, the feature response communicating the simulated behavior.

Abstract: A shift register which receives a transmission clock signal, which is shifted according to the transmission clock signal, and which outputs a gate signal a predetermined time after reset; a reset circuit which outputs a reset signal for resetting the shift register when the reset circuit receives an input of a step signal for driving the stepping motor; and a switching element which receives the gate signal of the shift register and which is switched between a blocked state and a conductive state are provided in a driving circuit of a stepping motor.

Abstract: A method for use in viewing compression and migration status is disclosed. A logical volume is selected for compression into a compressed logical volume. A destination storage pool for the compressed logical volume is selected. The logical volume is compressed during migration of the logical volume to the destination pool. Unified status information of progress of the compression and migration is presented. A system for use in viewing compression and migration status is also disclosed.
