  • Apparatus and method to assign pseudotime attributes to one or more logical volumes
    Patent number: 6895466
    Abstract: A method to assign a premigration pseudotime attribute and a stubbing pseudotime attribute to a logical volume. The method defines a plurality of host requests, and associates with each host request a pseudotime range. The method further maintains a logical volume in a first information storage medium at a first time, and determines if a user provides a host request for that logical volume. If a user provides a host request for that logical volume, then the method assigns to the logical volume a premigration pseudotime attribute, and a stubbing pseudotime attribute, comprising a time within the pseudotime range associated with the host request. If, on the other hand, a user does not provide a host request for the logical volume, then the method assigns to that logical volume the first time as said premigration pseudotime attribute, and said first time as said stubbing pseudotime attribute.
