Computer system, and method for managing resource pool information
First Claim
1. A computer system comprising:
- a plurality of computers;
a resource management computer that manages configuration information on the computers;
a storage subsystem for storing data;
a network that couples the plurality of computers with each other and couples the plurality of computers with the storage subsystem; and
a plurality of SNW connection devices that couple at least one of the plurality of computers with the storage subsystem via a SAN, whereinat least one of the SNW connection devices operates as a PnP SAN connection device for executing a SAN boot,a first computer coupled with the PnP SAN connection device transmits the configuration information on the first computer to the resource management computer,the storage subsystem obtains property information on the PnP SAN connection device with reference to SAN type information for managing information on computers coupled with the plurality of SNW connection devices, and transmits the property information to the resource management computer,the resource management computer determines whether or not to set the first computer as a target to execute the SAN boot on the basis of information on a configuration requirement required for a computer to be a target to execute the SAN boot, the property information, and the configuration information, and, according to a result of the determination, manages the first computer as a target to execute the SAN boot and presents information on the target to execute the SAN boot,the resource management computer obtains fabric information indicating information on devices connected to each SNW connection device from the plurality of SNW connection devices and, in response to an instruction to set the PnP SAN connection device, sets the PnP SAN connection device and presents information on the set PnP SAN connection device,the storage subsystem obtains the fabric information and holds the fabric information as theSAN type information, and manages the SNW connection device set as the PnP SAN connection device in the SAN type information, andthe PnP SAN connection device updates the fabric information in response to connection of a newly added computer,the resource management computer determines whether the newly added computer satisfies the configuration requirement and determines whether to include information on the newly added computer into targets to execute the SAN boot, andthe storage subsystem includes the information on the newly added computer into information on devices connected to the PnP SAN connection device in the SAN type information.

Abstract
A computer system is provided that is capable of reducing an administrator'"'"'s operational errors by connecting a new server to a SAN and automating a SAN boot setting, and capable of lightening the administrator'"'"'s task of checking for a wrong connection by detecting a wrong connection made when a new server is connected to an SNW connection device. Once a new server connected to a PnP SAN starts with a boot program obtained from a boot management server, the new server transmits configuration information on the new server to a resource management server. In response to a request from the resource management server, a storage device refers to PnP SAN information to transmit SAN information on a storage network connection device to which the new server is connected. The resource management server determines to add the new server to a resource group on the basis of the SAN information and requirement information. The resource management server sets the storage device and the new server for SAN-booting the new server.
