Patent ID: 7962672

Claim:
A computer implemented method for storage configuration comprising: defining one or more initiator groups each including one or more initiator ports; 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 which devices of said first storage group are accessible using one or more paths, each of said one or more paths specified using an initiator port from said first initiator group and a target port from said first target group, wherein automated logical unit assignment is performed for each device included in said first storage group, a different logical unit sequence being associated with each different path over which devices are accessible so that if a same logical device is accessible on two different paths, said same logical device is assigned a first logical unit identifier on a first of said two different paths in accordance with a next identifier of a first identifier sequence for the first path and a second logical unit identifier on a second of said two different paths in accordance with a next identifier of a second identifier sequence for the second path.
