In one embodiment, a data structure stores information about the number of client virtual I/O adapters, the number of possible destination VIOS hosts and the number of available slots on those hosts. The information is used to iteratively assign adapters to available slots of the VIOS hosts of the destination server to which a client partition is to be migrated. A method comprises testing the data structure to determine whether conditions exist that make allocation of the adapter to a VIOS host unquestionable.

Generally speaking, systems, methods and media for detection and network reconfiguration upon changes in dynamic host configuration protocol (DHCP) IP addresses are disclosed. Embodiments of a method may include setting a renew time and a rebind time of a DHCP configuration and establishing an IP address with a first DHCP server. Embodiments may also include, after passage of the renew time, transmitting a renew request to the first DHCP server at its IP address and, in response to failure to receive an acknowledgement message from the first DHCP server, determining if the first DHCP server IP address is still valid. Embodiments may also include, in response to determining that the first DHCP server IP address is not still valid, retrieving a second, different DHCP server IP address from a network change event signal and configuring a network adapter based on the second DHCP server IP address.

Automatic network reconfiguration upon changes in DHCP IP addresses

A method, system and apparatus for dynamically reconfiguring partitions of a partitioned computer system are provided. Here, dynamically reconfiguring a partition is defined as being able to reconfigure the partition while the partition is operational. Using a graphical user interface (GUI), a user may indicate a plurality of resources that are to be involved in a partition reconfiguration. However, the partition is actually reconfigured one resource at a time. If one of the resources is memory, then memory is allocated to the partition or de-allocated from the partition one logical memory block (LMB) at a time. In reconfiguring partitions, resources may be removed, added or moved from one partition to another. Moving resources from one partition to another entails removing the resources from one partition and adding it to the other partition. After a partition re-configuration, a resource allocation table is updated. All this is done transparently to the user.

Procedure for dynamic reconfiguration of resources of logical partitions

A method, apparatus, and computer instructions for providing addresses to clients. A request is received from a client for an address. A determination is made as to whether authentication information is present in the request. A verification process is performed using the authentication information if the authentication information is presenting the request. A determination is made as to whether the authentication information is authenticated. A privileged address is provided to the client in response to the authentication information being authenticated.

A system and method are provided to allow a user to update a computer system without having to interact with an initialization, or configurator software utility, or program. More particularly, the present invention allows a system provider, manufacturer, or service provider to create an installation file that, when provided to a user, will configure a system to accommodate newly added/removed hardware automatically. A base model and a new model of the system are maintained. The new model will include one or more different configurations, such as new graphics adapters, communications adapters, I/O controllers, or the like. The provider will have created a recovery/install image to be used with the base model. An operating system including a configurator program will be running on both the base model system and new model system. Software, such as device drivers, to be used with the new model's changed hardware configuration is installed on the new model system and initialized using its configurator program. A file for the new model is created using vital product data for the base model system. This new model configuration file is then installed on the base model machine and its configurator program is run. The configuration information (including the new model configuration data) is then stored as a system image and a script file is added to this system image. This new model image is then made available to end users, by a CD or the like, having a new model system. The script file in the new model image will specify a start priority that will allow it to be called before the configurator program and it will proceed to initialize the system with the appropriate software captured from the system provider's new model machine.

A method, apparatus, and computer instructions for improving performance and scalability of common information model object (CIMOM) by using a hardware management console (HMC) repository. The HMC repository includes storage of HMC objects, an HMC object model and a common interface (CIM Wrapper) for accessing to HMC objects. The HMC object model allows the user to store and retrieve the CIM objects and their associations efficiently. A CIM provider may access HMC objects through a common interface (CIM Wrapper), so that different repositories are allowed to be used without significant changes to the underlying server code (CIM provider). A CIM provider may also call the HMC repository directly for more efficient operations because the number of times conversions made between the CIM object and the repository object are greatly decreased.
