摘要:
A computer system comprising a storage device including a copy pair of a copied volume and a host computer is provided. The management computer detects a change in the state obtained by monitoring the state of the copy pair, and according to the result of detection, changes the configuration of a cluster constituted by a virtual machine using data stored in the volume, and a host computer using the volume.

A computer system is provided that is capable of reducing an administrator's operational errors by connecting a new server to a SAN and automating a SAN boot setting, and capable of lightening the administrator's task of checking for a wrong connection by detecting a wrong connection made when a new server is connected to an SNW connection device. Once a new server connected to a PnP SAN starts with a boot program obtained from a boot management server, the new server transmits configuration information on the new server to a resource management server. In response to a request from the resource management server, a storage device refers to PnP SAN information to transmit SAN information on a storage network connection device to which the new server is connected. The resource management server determines to add the new server to a resource group on the basis of the SAN information and requirement information. The resource management server sets the storage device and the new server for SAN-booting the new server.
摘要:
A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource.

It is an object of the present invention to provide a technique that can comprehensively manage plural kinds of network addresses allocated to virtual computers. In various embodiments, a MAC address, an IP address, and virtual communication interface identification information are allocated anew to a virtual computer to be created anew and the MAC address, the IP address, and the virtual communication interface identification information are set to be unable to be allocated anew.
摘要:
There is provided a computer system comprising a first storage system and a second storage system coupled to the first storage system. The first storage system provides a first storage area. The second storage system provides a second storage area. The second storage system reads and writes the requested data from and to the first storage area associated with the second storage area; specifies the first storage area associated with the second storage area from which the data is to be erased upon reception of a request for erasing the data stored in the second storage area; and transmits the request for erasing the data to the first storage system providing the specified first storage area. The first storage system erases the data stored in the specified first storage area, based on a data erasure condition included in the request for erasing the data.
摘要:
A transdermal patch containing a drug comprising formoterol and/or a salt, a solvent for the drug, a pressure-sensitive adhesive comprising an ethylene/vinyl acetate copolymer resin and at least one of a filler and a plasticizer. The patch is substantially water-free. The patch serves to promote percutaneous absorption of the formoterol and/or a salt thereof and allow the efficacy of the drug to stably persist for a long period of time. The patch is thus effective for diseases such as asthma, which can be cured or prevented by exciting &bgr;-receptors.
摘要:
It is an object to use a storage region in an efficient manner and maintain a performance of a storage system. A volume group GR11 includes reference volumes 1411, 1413, and 1415 and source volumes 1412, 1414, 1416, and 1417 that derive from the reference volumes. Each of the volumes stores only the difference data from a volume that is a parent thereof. A volume that is a cause of a problem is moved or copied from a pool of the moment 1410 to other pool 1420. A configuration of a volume group is modified.
