| 20090055738 | Techniques for Providing Dynamic Help Content for a Command Line Interface - A technique for providing assistance to a user of a system includes receiving a current command entered into a command line interface of the system and determining a current state of a system. Command help for the current command is then generated based on the current state of the system. | 02-26-2009 |
| 20090172541 | METHOD AND SYSTEM FOR PROVIDING DYNAMIC CONTEXT ASSIST FOR A COMMAND LINE INTERFACE - A method, system, and computer program product for providing dynamic context assistance to a user of a system, such as a storage system. One or more current command line interface (CLI) entries that are entered in a CLI of the system are received and a current state of the system is determined. Dynamic context assistance is then generated for one or more current CLI entries based on entered values of the one or more CLI entries. In this regard, the dynamic context assistance can be generated and displayed in a text or graphical form when one or more dynamic context assist keys are entered in the CLI in conjunction with the current CLI entry. | 07-02-2009 |
| 20090198699 | REMOTE SPACE EFFICIENT REPOSITORY - A method for storing data includes establishing a space efficient storage system including a virtual repository, a staging repository and a remote repository. The virtual repository includes a first pointer to the staging repository, and the staging repository includes a second pointer to the remote repository. The method further includes receiving data at the virtual repository, storing the received data in the staging repository based on the first pointer, and determining a data access frequency based on the storage in the staging repository. In addition, the method includes comparing the determined data access frequency to a threshold frequency and transferring the stored data to the remote repository based on the second pointer and comparison and storing the stored data at the staging repository based on the comparison. | 08-06-2009 |
| 20100175075 | METHOD FOR EXECUTING A SOFTWARE ROUTINE IDENTIFIED IN A TASK OBJECT - A method for executing a software routine identified in a task object is provided. The method includes accessing a list of software routine identifiers associated with software routines that are executable on a computer server. The method further includes generating a task object generation command having at least a first software routine identifier, parameter data, and link task information and generating a second task object in response to the task object generation command. The second task object includes the first software routine identifier, the parameter data, and the link task information. The method further includes adding the second task object to a task execution queue on the computer server and executing the first software routine identified by the first software routine identifier in the second task object on the computer server to obtain at least a first result value, when the first flag value is a first predetermined value and the result parameter associated with the first task object corresponds to a second predetermined value. | 07-08-2010 |
| 20100175076 | METHOD FOR EXECUTING A SOFTWARE ROUTINE IDENTIFIED IN A TASK OBJECT - A method for executing a software routine identified in a task object is provided. The method includes accessing a list of software routine identifiers associated with software routines that are executable on a computer server, and generating a task object generation command having at least a first software routine identifier, parameter data, and event information. The event information has an event identifier and a first flag value. The method further includes generating a first task object in response to the task object generation command, which includes the first software routine identifier, the parameter data, and the event information. The method further includes adding the first task object to a task execution queue on the computer server, and executing the first software routine identified by the first software routine identifier in the first task object on the computer server to obtain at least a first result value, when an event listener on the computer server determines that the first flag value is a first predetermined value and an event associated with the event identifier is detected. | 07-08-2010 |
| 20110191563 | ON DEMAND CONVERSION OF STANDARD LOGICAL VOLUMES TO THIN-PROVISIONED LOGICAL VOLUMES - A method for concurrently converting a standard volume to a thin-provisioned volume includes initially establishing metadata for a thin-provisioned volume. The method then updates the metadata for the thin-provisioned volume to point to extents residing in a standard volume. The method then suspends I/O to metadata for the standard volume. Upon suspending the I/O, the method migrates control of the extents in the standard volume from a standard-volume control algorithm to a thin-provisioned-volume control algorithm. The method then resumes the I/O to the metadata for the thin-provisioned volume. Using this technique, standard volumes may be rapidly converted to thin-provisioned volumes while minimally disrupting I/O to the volumes. A corresponding apparatus and computer program product are also disclosed and claimed herein. | 08-04-2011 |
| 20120173856 | Determining Logical Configuration Commands to Create a Logical Object - An approach to generating logical configuration commands for logical objects in a system. A method may involve receiving a command requesting the logical configuration commands to configure the specified logical object (subject logical object) and the logical objects that support the logical object (the support logical objects). The method may also involve determining what logical objects in the system support the subject logical object. This may require determining the support logical objects that directly support the subject logical object, and then recursively examining each support logical objects to find the logical objects on which they depend. For each logical object (whether the subject logical object or one of the support logical objects), the method may involve determining the logical configuration commands to appropriately create and modify the logical object. The logical configuration commands may then be presented to the user. | 07-05-2012 |
