Abstract
Access from a user to a plurality of disk units is managed by establishing a change authority over configuration information of logical volumes for each user ID at a management client and by storing the change authority as user information and access right information in an access management server. The access management server generates volume configuration information of a disk array unit based on the stored user information and access right information and then establishes the volume configuration information at the disk array unit.
Claims14
An access management server for managing access to a plurality of disk units, comprising:
- a storage device which stores information regarding logical volumes logically divided and stored in each of said disk units and information for allowing for establishment of an access right over a logical volume for each user identifier;
- and
- a controller which transmits information regarding a logical volume for which establishment of an access right is permitted based on a transmitted user identifier from said storage device.
An access management server for managing access from a user to a plurality of disk units, comprising:
- means for holding access right information defined for each user identifier with respect to logical volumes logically divided and stored in each of said disk units;
- and
- access control means coupled to said holding means for determining whether said access is permitted or prohibited based on the user identifier and said access right information, in response to reception of a request to access said logical volumes.
A disk array system comprising a disk array unit having a plurality of disk units and an access management server for managing access from a user to said disk array unit,
- wherein said access management server comprising the steps of:
- means for holding access right information defined for each user identifier with respect to each logical volume stored in each of said disk units;
- and
- access control means for determining whether said access is permitted or prohibited based on said user identifier and said access right information, in response to reception of a user's request to access said logical volume.
An access management method of managing an access from a user to a plurality of disk units, comprising the steps of:
- determining whether said access is permitted or prohibited based on access right information defined for each user identifier with respect to each logical volume stored in each of said disk units, in response to a user's request to access said logical volumes;
- and
- transmitting a result of the determination by the determining step to the user.
An access management method of managing access to a plurality of disk units, comprising the steps of:
- identifying information on a logical volume for which establishment of an access right is permitted with respect to a transmitted user identifier, based on said user identifier;
- and
- establishing a user identifier for which an access right can be established with respect to said identified logical volume.
