Abstract:
1. A method to maintain information by assigning one or more storage attributes to each of a plurality of logical volumes, comprising the steps of: forming a first dataset; assigning one or more storage attributes to said first logical volume; selecting one or more storage construct names for said first dataset; issuing a first mount command, wherein said first mount command comprises said one or more storage construct names and an empty clone volser field; writing a first portion of said first dataset to a first logical volume; saving each of said one or more storage construct names as a different one of said one or more storage attributes; assigning a first identifier to said first logical volume; determining if an LEOV (logical End of Volume) is approaching; operative if the LEOV of said first logical volume is approaching, issuing a second mount command, wherein said second mount command includes a clone volser field comprising said first identifier, and wherein said second mount command does not comprise said one or more storage construct names; mounting a second logical volume; writing a second portion of said first dataset to a second logical volume; and assigning said one or more storage attributes to said second logical volume.
