A pool that is a storage area group composed of a plurality of real pages based on a plurality of RAID groups is managed. The storage system carries out the rebuild processing that includes the steps of copying each of data that has been stored into all allocated real pages among all real pages based on a specific RAID group to an unallocated real page based on at least one RAID group separate from the specific RAID group, allocating a real page of each copy destination to each virtual page of an allocated destination of an allocated real page of each copy source, and canceling an allocation of an allocated real page of each copy source to a virtual page.

An aligned workpiece is mounted on and held by a holding table, and a support board separating mechanism separates a support board from a semiconductor wafer. Herein, a double-faced adhesive tape is left on one of the support board and the semiconductor wafer. Either the support board or the semiconductor wafer on which the double-faced adhesive tape is left is transported to an adhesive tape peeling mechanism while being held by the holding table, and the double-faced adhesive tape is peeled off and removed from the surface of thereof. The separated semiconductor wafer and support board are collected independently.

A SAN manager acquires configuration information from devices constituting a SAN and produces a corresponding relationship between a host computer and a virtual volume (virtual volume mapping) and a corresponding relationship between the host computer and a real volume (real volume mapping). Based on those pieces of mapping information, the SAN manager outputs a corresponding relationship between virtual and real volumes. Meanwhile, the failure notification messages received from the in-SAN devices are construed to detect and output an influence of the failure upon the access to a real or virtual volume. Furthermore, when receiving a plurality of failure notifications from the devices connected to the SAN, the plurality of failure notifications are outputted with an association based on the corresponding relationship between real and virtual volumes.

A disk array includes a drive management unit, which is a program for identifying kinds of disk devices and managing different disk devices separately, and a drive management table for storing information to be utilized by the drive management unit. The disk array further includes a program for managing accumulated time of disk devices. The program includes a drive lifetime setting portion for setting lifetimes of drives, a drive start/stop portion for intentionally starting/stopping ATA disk devices, and an operation time measurement portion for measuring accumulated operation time. Since it is necessary to be conscious of difference in reliability and performance among disk devices when forming a RAID, a drive kind notification unit, which is a program for notifying of the kind of a disk device when forming the RAID, is provided.

An adhesive tape joining apparatus of this invention adopts an inverted “T”-shaped layout configured with a rectangular section that extends laterally when being viewed in a plane and a protrusion section that is coupled on a center of the rectangular section. An adhesive tape joining part is disposed in the protrusion section and joins an adhesive tape to a ring frame and a wafer. A transport mechanism is disposed in the rectangular section and transports the wafer, the ring frame, and the wafer held by the ring frame. An electronic substrate processing unit is disposed in at least one of two regions adjoining to the rectangular section with the protrusion section being interposed therebetween, and is coupled to the transport mechanism.
摘要:
A joint detector detects a joint in an adhesive tape supplied from a tape supply section, and a computing unit determines a suitable cutting position of the adhesive tape for removing the joint in accordance with the detected results. A controller controls each mechanism to operate so as to satisfy the determined results by the computing unit. Thereafter, the adhesive tape including the joint is cut and removed.

An adhesive tape is supplied to a back face side of a ring frame, joined to the ring frame with a joining roller, and cut by pivoting a cutter blade along the ring frame. Subsequently, an inspection ring of an inspecting mechanism perform suction on the adhesive tape while contacting the adhesive tape adjacent an inner periphery of the ring frame. Separation of the adhesive tape from the ring frame is determined based on variations of the suction pressure. When the separation of the adhesive tape from the ring frame is detected, the adhesive tape is joined again with the joining roller provided in the cutter mechanism.

During relative and horizontal movement of a mount frame, in which a semiconductor wafer with a protective tape is supported on a ring frame through a supporting adhesive tape, and a joining member, a position of an end edge of the protective tape is detected in a non-contact manner. Based on the detection result, a joining member is stopped in the position of the end edge of the protective tape and is moved close to the semiconductor wafer to press and bring a separation tape against and into contact with an end of the protective tape. In this state, the mount frame and the joining member are relatively and horizontally moved to join the separation tape onto the protective tape. Then, the mount frame and the joining member are relatively and horizontally moved to separate the separation tape together with the protective tape from a surface of the semiconductor wafer.

A computer system for preventing data loss that includes: a first storage system having a data storage extent for storing data sent from a host computer; a second storage system having at least one actual replicated data storage extent associated with the data storage extent; an archive appliance having a storage medium associated with the replicated data storage extent in the second storage system; and a data copy unit for controlling copy processing for reading data from the data storage extent in the first storage system and writing the read data to a first actual replicated data storage extent in the second storage system in accordance with specific configuration information. The system also has a connection switching unit for changing the specific configuration information so that a second actual replicated data storage extent, instead of the first actual replicated data storage extent, is associated with the data storage extent.
