An I/O module includes a switch module, a redundant array of independent disks (RAID) controller and a baseboard management controller (BMC). A first address for a first component of the plurality of components is received. The first address is provided by a user. The switch module is queried for additional addresses for additional components of the plurality of components. The switch module obtains the additional addresses for the additional components from a first persistent storage location associated with the switch module. The first and additional addresses for the first and additional components are stored in a second persistent storage location accessible by the BMC, the switch module, and the RAID controller. Synchronization of the first and additional addresses for the first and additional components in the second persistent location is controlled by the BMC.

Component discovery in multi-blade server chassis

A method for discovering hosts on a multi-blade server chassis is provided. A switch, operational in the multi-blade server, is queried for first world-wide name (WWN) information of the hosts. The first WWN information is known to the switch. The first WWN information is saved on a redundant array of independent disks (RAID) subsystem of the multi-blade server chassis. A system location for each of the hosts is mapped to the RAID subsystem.

Host discovery in multi-blade server chassis

A method to change the IP address of a server from a remote operator station, where that server comprises an HTTP server having a first IP address, and where that server is capable of communicating with one or more remote operator stations. One of those remote operator stations submits to the server, using the first IP address, an IP address change request. That IP address change request includes discontinuing use of the first IP address and commencing use of a second IP address. After receipt of the IP address change request, the server generates an HTML page comprising an embedded applet, where that applet is capable of monitoring the TCP/IP connection between the remote operator station and the server. The server provides that HTML page/applet to the remote operator station. Thereafter, the remote operator station continuously displays the status of the IP address change request using the provided applet. After the IP address change request is completed, the remote operator station communicates with the server using the second IP address.

Anomaly-driven software for capturing and automating responses to computer anomalies is disclosed. Computer anomalies are processed by identifying the occurrence of an anomaly and correcting the computer anomaly by initiating a stored corrective action based on a user's input for resolving the anomaly.

Anomaly-driven software switch to capture event responses and automate recovery

Disclosed are a system, a method, and article of manufacture to configure information storage and retrieval systems. A configuration loader receives configuration commands from a configuration loader user interface. Upon receipt of configuration commands, the configuration loader transfers storage controller configurations from information storage and retrieval system configuration sources to target information storage and retrieval systems. Threading technology is used to apply a thread manager for managing threads to accomplish the configuration transfers. Multiple physical and/or logical configurations may be transferred simultaneously using the threading technology.

Storage configuration loader

A method for modifying a logical library configuration from a remote management application which reduces the number of separate UI display panels a user has to view, and also reduces the number of pages requested from the server. A single UI display panel displays a configuration of all logical libraries of a similar media type in the single display panel. The configuration of all logical libraries of a similar media type can be modified within a configuration range, wherein a modification of one logical library results in the display panel displaying the effects of the modification on other defined logical libraries. For each separate logical library, the single UI display panel displays its allocated number of drives, its allocated number of storage slots, and its allocated number of control ports. The validity of a selected configuration is checked by automatically adjusting the hardware allocation of other effected libraries whenever the configuration of one logical library is changed.

Method of modifying a logical library configuration from a remote management application

Provided is a method, system, and program for determining a configuration of a logical array including a plurality of storage devices. A selection of a number of storage devices is received to include in the logical array. A determination is made of a number of groups in which to include the selected number of storage devices, wherein each group includes at least one storage device maintaining user data and parity data for the user data in the group. Determining an assignment of the selected number of storage devices to the determined number of groups and allocating the storage devices to the determined number of groups according to the determined assignment.

Provided is a method, system, and program for generating a status page to display on a computer display. A request for status information on a resource is received. A determination is made of an operation being performed with respect to the resource. Data is generated to display a progress bar indicating a percent of the operation that has completed. A first part of the progress bar indicates a percent of the operation that has completed and a second part of the progress bar indicates a percent of the operation that has not completed. A determination is made of an attribute of the operation. Data is then generated to display information with one of the first part or second part of the progress bar indicating the determined attribute of the operation.

Method, system, and program for generating a progress indicator

According to the present invention, there is provided a method, system and program storage device for maintaining an active root filesystem in a storage subsystem comprising a plurality of storage devices. The method, system and program storage device comprise searching root partitions of the plurality of storage devices for a valid root filesystem, the root filesystem including mount points associated with the plurality of storage devices; mounting a root filesystem that is found first as the active root filesystem and mounting root partitions of the plurality of storage devices to the associated mount points within the active root filesystem; and replicating the active root filesystem across the plurality of storage devices in the storage subsystem, wherein the storage subsystem is bootable from any storage device of the plurality of storage devices that includes a replica of the active root filesystem. The method, system and program storage device further replicate the active root filesystem in response to storage subsystem configuration requests, and notifications of new or replaced disk drives being installed in the storage subsystem.

A generic device driver simulator having the knowledge of the device specific behavior moved out of simulator program code is disclosed. The generic device driver simulator includes a generic device driver for supporting application functions without device specific coding included therein, a database including device specific models of device drivers supported by the generic device driver and an interpreter for controlling the generic device driver according to the definitions of functions and data structures in the database. The generic device driver simulator also includes a watcher for defining watchpoints, the watchpoints identifying types of calls from the application. The watcher displays information when a watchpoint is triggered by a call from the application. The interpreter includes an input script for each device function or for multiple device functions that are supported by the generic device driver. The watcher supports the execution of an input script in the interpreter in response to a watchpoint being triggered.

Generic device driver simulator and method

In a user interactive multitasking data processing system, a comprehensive managing subsystem is constructed for managing queued processing of tasks of a particular type that ordinarily are not handled on a queued basis by the associated operating system. The subsystem is constructed around a task control utility which lacks capability for controlling required display presentation and queue managing functions for the respective task type. The utility is adapted to interface with operating system elements that ordinarily perform display and queue management functions relative to tasks other than the tasks handled by the utility. In the embodiment specifically disclosed, a utility for managing queued processing of page image data (e.g. data produced by document scanners or other image capture devices) interfaces with Presentation Manager and Print Spooler elements of the OS/2.TM. Operating System. The utility per se lacks functional capabilities for display and queue management, which are required for managing the processing of associated image data, and therefore requires considerably less storage capacity than it would need if such capabilities were included. These functions are performed by the OS/2 elements to which the utility interfaces. However, the utility accesses image data in the queues created by the OS/2 Spooler transparent to (i.e. without cooperation of) the Spooler, when transferring such data between the queues and associated processing applications. Thus, the utility operates more efficiently than it would if required to invoke the Spooler when making such transfers.
