| 1. A system for storing data comprising:
a plurality of host computers; and
a storage system coupled to the plurality of host computers and having a plurality of logical volumes,
wherein, based on volume management information defining a particular computer identification as a computer identification
of a host computer which is allowed to access a particular logical volume of the plurality of logical volumes, the storage
system is configured to permit one of the plurality of host computers using the particular computer identification to access
the particular logical volume, and
wherein, based on user management information defining the particular computer identification as a computer identification
used by a particular user identified by a particular user name, in response to a login request including the particular user
name, each of the plurality of host computers is configured to acquire the particular computer identification, set up the
particular computer identification as its own computer identifier, and transmit a request including the particular computer
identification to the storage system,
so that when a first one of the plurality of host computers receives the login request including the particular user name,
the first one of the plurality of host computers is allowed to access the particular logical volume, and when a second one
of the plurality of host computers receives the login request including the particular user name, the second one of the plurality
of host computers is allowed to access the particular logical volume,
wherein an Operating System of the particular user is stored in the particular logical volume, and
wherein, when one of the plurality of host computers is allowed to access the particular logical volume, the one of the plurality
of host computers boots up the Operating System of the particular user from the particular logical volume.
