摘要:
A separator separating/collecting operation is controlled in correspondence with an adhesive tape supplying operation such that a separating point of a separator on an adhesive tape when supply of the adhesive tape and separation of the separator are stopped is deviated from a surface of a semiconductor wafer in a subsequent adhesive tape affixing operation.

In a storage system having local and remote disk systems, a system is described for selectively controlling the security of data on a volume by volume basis, for transparently exchanging encryption keys between the local and remote disk systems, and for controlling when encryption is used in the storage of data.

Upon detection of an error such as a malfunction occurring at a drive mechanism, a sensor transmits an error signal to a control section. The control section selects character information about details of the error corresponding to the error signal and an image representing the drive mechanism where the error occurs and a position of the sensor in the drive mechanism, and reads out the character information and the image from a storage part. Then, the control section allows a liquid crystal display device to display error information in which a first image of character information is combined with a second image of an error occurrence site in the drive mechanism. After correction of the error, an operator touches a GUI on a screen to thereby check an operation of the drive mechanism.

A related art has not taken account of the authority to manage the physical configuration of a storage system. Therefore, the configuration of a storage system cannot be safely managed. Moreover, storage systems to be used by administrators may be duplicate. The availability of an entire computer system is degraded due to stoppage of a storage system caused by scheduled maintenance or the like. Responsively to a manipulation a storage administrator performs in order to allocate or un-allocate a volume, the authority to manage the physical configuration of a storage system is given to the storage administrator or the storage administrator is deprived of the authority. Specifically, a volume allocation program installed in a management computer gives the storage administrator the authority to manage the physical configuration of a storage system, which includes a created volume, responsively to creation of the volume. Moreover, a volume un-allocation program installed in the management computer verifies responsively to un-allocation of a volume whether the storage administrator should be deprived of the authority to manage the physical configuration of the storage system including the un-allocated volume. If the storage administrator is recognized to be deprived of the authority, the storage administrator is deprived of the authority. Owing to the two programs, the storage administrator can manage both a physical configuration and a logical configuration exclusively to other storage administrators.

Computer systems having a plurality of storage systems could not detect addition of storage systems or configuration changes thereof and automatically redistribute existing volumes based on “hints” provided when the volumes were created. A management computer, which is connected via a network to storage systems having volumes connected via a network to a host computer and which stores data used by the host computer, keeps correspondences between levels indicating specific performances of volumes and storage system characteristics indicating performances of the storage systems. From a first storage system, a level is obtained indicating a performance of a volume of the first storage system allocated to the host computer. The storage system characteristics of the first storage system corresponding to the obtained level indicating the performance of the volume, and storage system characteristics of another storage system are referenced, and the performances of the volumes of the storage systems are compared.

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.
摘要:
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.
摘要:
A volume management system, a managing computer, a host, and a volume management method being capable of regulating the authorities of users and avoiding misoperations are provided. The volume management system comprises a storage having volumes served as a storage region, a managing computer, and a plurality of hosts used by users obtaining an operation authority over the volume. Two or more users can use an identical volume. Upon obtaining an operation content of one user for at least one of the volumes over which two or more users have the operation authority, the managing computer determines from an attribute of the volume and the operation authority of the two or more users over the volume whether the operation content is executable. When the operation content is not executable, the operation content is restrained.
摘要:
In a computer system that includes plural host computers and plural data storage apparatuses (storage systems) and performs, in particular, virtualization of a data storage area, unless zoning is performed correctly to activate a zone between a data storage apparatus holding a virtualized data storage area and a device holding a data storage area storing actual data, the storage area storing actual data cannot be used from the host computers. The present invention provides a mechanism for grasping a relation between the virtualized data storage area and the data storage area storing actual data, configuring a zone between data storage apparatuses holding the data storage areas as a special zone, and always activating the special zone at the time of zoning configuration. The invention further provides a mechanism for grasping a relation between the virtualized data storage area and the data storage area storing actual data, associating a zone for connecting the host computers and a first-tier data storage apparatus and a zone for connecting the first-tier data storage apparatus and a second-tier data storage apparatus, and activating a second zone according to switching activating first zone.
摘要:
Long-term preservation of data (archive) has become more important. In order to reduce the maintenance cost for data, a first storage system consolidating a disk system and an MT library system has a disk interface with respect to a host computer and has a function of storing a logical volume in an MT. In addition, the first storage system has a function of managing information such as information indicating in which MT the logical volume is stored, and in which slot of a library the MT is stored. By using such functions, it is possible to integrally manage storage areas of the disk system and the MT library as logical volumes, thereby reducing the management cost.
