Method, apparatus, and computer product for managing operation

Abstract

A system resource manager of a site management server registers a server domain as a group of servers having a uniform physical wire connection, registers a server group as a group of servers that use uniform software in a registered server domain, and changes an application of a server by controlling a switch of software that is stored in a RAID device connected to a server belonging to a registered server group via a SAN for each application and that is used by the server.

1 . An apparatus for managing an operation of resources constituting an information processing system, the apparatus comprising:
 a server-information storage unit that stores information on a plurality of servers belonging to a server group;   a storage unit that stores number of servers being able to be switched from a first server group to a second server group, identification information of the first server group, identification information of the second server group and switching schedule information including timing information on switching from the first server group to the second server group; and   a switching unit that identifies, depending on the number, a server switched from the first server group and a server group the server being switched to, and switches the identified server to the identified server group as the second server group with timing specified by the timing information.   
     
     
         2 . The apparatus according to  claim 1 , wherein
 the switching unit switches the identified server with different timing based on number of servers belonging to the first server group.   
     
     
         3 . A method of managing an operation of resources constituting an information processing system, the method comprising:
 identifying, depending on number of servers being able to be switched from a first server group to a second server group, a server switched from the first server group and a server group the server being switched to, the identifying identifies using a server-information storage unit that stores information on a plurality of servers belonging to a server group and a storage unit that stores the number, identification information of the first server group, identification information of the second server group and switching schedule information including timing information on switching from the first server group to the second server group; and   switching the identified server to the identified server group as the second server group with timing specified by the timing information using the storage unit.   
     
     
         4 . The method according to  claim 3 , wherein
 the switching switches the identified server with different timing based on number of servers belonging to the first server group.   
     
     
         5 . A computer-readable, non-transitory storing medium that stores therein a computer program for managing an operation of resources constituting an information processing system, the computer program causing a computer to execute:
 identifying, depending on number of servers being able to be switched from a first server group to a second server group, a server switched from the first server group and a server group the server being switched to, the identifying identifies using a server-information storage unit that stores information on a plurality of servers belonging to a server group and a storage unit that stores the number, identification information of the first server group, identification information of the second server group and switching schedule information including timing information on switching from the first server group to the second server group; and   switching the identified server to the identified server group as the second server group with timing specified by the timing information using the storage unit.   
     
     
         6 . The computer-readable, non-transitory storing medium according to  claim 5 , wherein
 the switching switches the identified server with different timing based on number of servers belonging to the first server group.
