Patent ID: 7036009

Claim:
A partition reconfiguration system wherein components constituting a computer system are partitioned based on pre-defined schedule information, comprising: a management node that issues a partition reconfiguration instruction based on the pre-defined schedule information; an operating system that, in response to the instruction, changes an operation state thereof to a partition re-configurable state in which a usual operation state is stopped to make reconfiguration possible and, at the same time, notifies that the operation state thereof has been changed, said operating system operating on said computer system; and a service processor that, in response to the notification notifying that the operation state has been changed, configures a partition according to information on components constituting the partition included in the instruction and, at the same time, changes the operation state of said operating system to the usual operation state, further comprising: partition reconfiguration schedule means for including at least date/time information indicating a date and time on which each partition is to be reconfigured and component information indicating information on components constituting the partition, wherein said management node periodically obtains the date/time information and the component information from said partition reconfiguration schedule means, compares the obtained date/time information with a current date/time, judges that a partition should be reconfigured if there is a matching date/time entry, and issues a partition reconfiguration instruction based on the corresponding component information.
