Abstract: A method, apparatus and program storage device for providing asynchronous status messaging in a data storage system Asynchronous events are returned from a target to an initiator in response to a Read Message from the initiator. The return status message may or may not be associated with a previously given command or Logical Unit (LUN).

Abstract: Provided are techniques for copying data. A volume container copyset that includes volume containers is received. A volume container copyset that includes volume containers is received. Each of the volume containers is associated with a copyset role, and each of the volume containers includes zero or more volumes, wherein each of the volumes in a volume container has the copyset role of that volume container. Sets of volumes are associated with a replication session, wherein each of the sets of volumes has one volume from each of the volume containers. Each of the sets of volumes has volumes associated with a copyset role that is associated with the volume containers with which each volume is associated. In response to determining that one of membership of one of the volume containers and a size of a volume in one of the volume containers has been modified, one or more corresponding volume containers in the volume container copyset are automatically modified.

Abstract: A volume container system automatically relates components of a storage area network in membership association of a volume container. The volume container is an abstract entity that maps a relationship between servers and storage devices. The entity captures network access control between servers and storage subsystems such as, for example, security, access, and zoning. Policies of the volume container guide operations in a volume container. The membership associates access and security within the volume container. The volume container reduces administration required for a storage area network, improves consistency in mapping, security, and zoning, and reduces complexity in consistently replicating a logical group of volumes, making failure recovery easier.

Abstract: Improved techniques for generating multidimensional output using a relational source database are disclosed. The techniques allow generation of instructions needed to access the source database in order to produce multidimensional output. The instructions do not need to be stored and can be generated dynamically. As a result, relational databases can be accessed without requiring additional programming and/or changes to the relational database. The source database can be a relational database that is accessed by a variety of conceptual accessing techniques (e.g., SQL). A Meta-data manager can be used to access the source database, as well as interact with a Meta-data modeler and a Meta-data outliner. The Meta-data modeler can be used to define a Meta-model. The Meta-data outliner can be used to create one or more Meta-outlines.
