A method and apparatus for managing at least one logical volume in a computer system that includes a processor, a storage system, and a plurality of paths coupling the processor to the storage system. The storage system stores a plurality of logical volumes that includes the at least one logical volume, and the at least one logical volume is accessible to the processor over at least two paths. The processor includes a mapping layer that assigns the logical volumes to store particular volumes of data. At least two distinct native names are created for the at least one logical volume, each native name corresponding to one of the paths over which the logical volume is accessible to the processor. A pseudoname is created for the distinct native names, and represents the at least one logical volume in a manner that is independent of the paths over which the logical volume is accessible to the processor. The pseudoname and the at least two native names each is made available to the mapping layer for assignment to store a volume of data, so that the mapping layer may assign the at least one logical volume to store a particular volume of data by assigning the pseudoname or either of the native names to store the particular volume of data.
