Abstract: A method of rapidly propagating grass and other living plant materials using a sod slurry. The method includes mechanically mixing sod having the desired species of grass or other living plant material with water, fertilizer and a slicking agent to produce a sod slurry which may be sprayed onto a prepared section of land using a conventional pump, hose and nozzle or other types of commercially available spraying equipment. Alternatively, the sod slurry may be poured from a bucket or other suitable container onto the prepared area of land. Mulch and other materials may be added to the mixing tank as appropriate for the selected species of grass or other living plant material. The soil portion of the sod cooperates with other portions of the slurry such as fertilizer or mulch to encourage rapid growth of the selected species of grass or other living plant material on the prepared area of land.

Abstract: A data storage system atomically suspends multiple duplex pairs across either a single storage subsystem or multiple storage subsystems. The duplex pairs are suspended such that the data on the secondary DASDs of the duplex pairs is maintained in a sequence consistent order. A host processor in the data storage system running an application generates records and record updates to be written to the primary DASDs of the duplex pairs. The storage controller directs copies of the records and record updates to the secondary DASDs of the duplex pairs. Sequence consistency is maintained on the secondary DASDs by quiescing the duplex pairs and then suspending the duplex pairs with change recording. Quiescing the duplex pairs allows any current write I/O in progress to complete to the primary DASD. The storage controller then locks out any subsequent write I/O from the host processor by raising a long busy signal to such subsequent write requests.

Abstract: A remote copy system incorporates dynamically modifiable ports on the storage controllers such that those ports can operate either as a control unit link-level facility or as a channel link-level facility. When configured as a channel link-level facility, a primary storage controller can appear as a host processor to a secondary storage controller. The primary storage controller can thereafter initiate multiple request connects (RQC) concurrently for servicing a single I/O request. In this manner, a first available path can be selected and system throughput thus improved since RQCs so not need to be sent serially from path to path looking for an available path.
