US Classification:

29429, 29714, 29779, 29820, 53436, 53459, 53469, 53473

Abstract:

An apparatus and method for manufacturing a drainage line unit. The apparatus includes a mandrel having an inner cavity. Rear, upper and front openings communicate with the mandrel cavity. Preferably, a controller connected to at least one sensor is operably positioned to control the apparatus. A pipe feeder feeds perforated vent pipe through the inner cavity of the mandrel from the rear opening to the front opening and therethrough. The pipe is positioned within the inner tube cavity so as to define a void space between the pipe and the wall of the mandrel. A hopper assembly has an exit port positioned for feeding a plurality of plastic bodies into the cavity. A blower produces a sufficient air flow through the mandrel cavity for moving the plurality of plastic bodies to substantially fill the void space so that the pipe emerges from the front opening of the mandrel surrounded by the plurality of plastic bodies. A sleeve feeder feeds a continuous sleeve of netting over the plurality of plastic bodies and the vent pipe emerging through the front opening of the mandrel to form a drainage line. A separator is positioned downstream from the front opening for fastening the continuous sleeve of netting to the vent pipe as the pipe emerges through the front opening of the mandrel, so as to substantially encase the plurality of plastic bodies around the vent pipe.

International Classification:

G06F 1116

US Classification:

709216, 714 13, 714 10

Abstract:

A system and method for recovering from a failure in a clustered environment sharing a common nonvolatile storage device. The first computer reserves the device by identifying itself in a reservation key associated with the device. The first device sends a signal to one or more backup computers informing the backup computers that the first computer is operational. When the first computer fails to operate, one of the backup computers breaks the first computers reservation to the storage device and writes a new reservation key to the reservation storage area identifying the backup computer as the reservation holder of the storage device. When the first computer is reinitialized, it reads the reservation storage area and does not attempt to break the reservation made by the backup computer. One embodiment provides for the first computer to request control from the backup computer upon being reinitialized whereupon the backup computer releases its reservation and relinquishes control. Another embodiment provides for the first computer to act as a backup computer.

International Classification:

G06F 1300

US Classification:

711114, 711112

Abstract:

A method, system, apparatus and computer program product for reducing the number of physical storage systems needed for a volume group to remain active are provided. This is accomplished by creating mirroring sets out of the physical storage systems in the volume group and by setting up a policy that so long as one mirror out of each mirror set is available, the volume group should be allowed to remain active. To activate a volume group (i. e. , when the computer system is turned or reset), there have to be at least one full mirror set and at least one mirror out of each remaining mirror set available. These two policies guarantee that there will always be valid metadata in the system.

US Classification:

711202

Abstract:

A method, system and apparatus for allowing a mirroring map to be used with more than one piece of data are provided. First, a mirroring map is created and given a name. Then, the name of the mirroring map and the mirroring map itself are stored into the computer system. When a piece of data is to be stored in accordance with the mirroring map any time thereafter, the name of the mirroring map is used to associate the mirroring map with the piece of data.

Abstract:

A method, system, and program product for controlling multi-node access to a disk storage system. In accordance with the method of the present invention, an active access authorization is set for a first node. The active access authorization enables read and write access by the first node to user and meta data within the disk storage system. A passive access authorization is set for a second node. The passive access authorization enables read-only access by the second node to logical volume management meta data within the disk storage system.
