Patent ID: 8397001

Claim:
A computer implemented method for storage configuration comprising: defining one or more initiator groups each including one or more initiator ports, wherein each of the one or more initiator ports identifies a port from which a request directed to a device is initiated; defining one or more target groups each including one or more target ports; defining one or more storage groups each including one or more devices; and creating a masking view including a first initiator group from said one or more initiator groups, a first target group from said one or more target groups, and a first storage group from said one or more storage groups, said masking view indicating that devices of said first storage group are accessible over a path set of one or more paths, each of said one or more paths in the path set specified using an initiator port from said first initiator group and a target port from said first target group, wherein a request issued over said each path directed to a device of the first storage group is issued from the initiator port to the target port and wherein the device is accessible to the initiator port through the target port, wherein said path set includes each different path formed using the first initiator group and the first target group, wherein said first storage group includes a plurality of devices and creating said masking view defines each device in said first storage group as accessible over each path in said path set.
