摘要： A virtual computer system has a plurality of computers for executing a program and a storage system connected to the computers via a network. A virtualization mechanism in a first computer of the plurality of computers generates at least one virtual computer on the first computer. The virtualization mechanism in the first computer executes at least one of a first judgment and a second judgment when a request for activating a first virtual computer of the at least one virtual computer is received, the first judgment being for judging whether or not the activation of the first virtual computer is prohibited based on first information stored in a memory of the virtualization mechanism, and the second judgment being for judging whether or not an identifier included in a logic I/O adapter device assigned to the first virtual computer is invalid based on second information stored in the memory of the virtualization mechanism. The activation of the first virtual computer is permitted or prohibited based on the executed judgment in response to the request for activating the first virtual computer.

摘要： A computer system, a virtual computer system and a computer activation management method for each system are disclosed. In the virtual computer system, a virtualization mechanism includes a WWN management table for storing the correspondence between a virtual HBA assignable to each virtual computer and the WWN, and a LPAR activation unit for checking the WWN corresponding to the virtual HBA assigned to the virtual computer based on the WWN management table at the time of activating the virtual computer and in the case where the WWN assumes a value indicating the activation suppression, suppressing the activation of the virtual computer. The virtual computer or the computer with the device identification information changeable, if triggered at a timing not intended by the user, can be prevented from being activated.

摘要： In a computer system, to enable a second computer to take over control of copying of data within the computer system, from a first computer that normally controls copying of data.The second computer selects from a plurality of storage systems a storage system to be accessed in order to acquire sub system pair information, and acquires sub system pair information from the selected storage system. Based on the acquired sub system pair information, the second computer generates system pair information that includes copy pair information relating to a plurality of storage areas belonging to the plurality of storage systems. The second computer initially selects a storage system directly linked to the second computer, and subsequently sequentially selects a storage system based on the acquired sub system pair information.

摘要： The data processing system comprises at least one first storage system, and at least one second storage system connected to the first storage system. The second storage system receives change information identifying pre-change and post-change copy destination storage areas in a change process for changing a copy destination storage area of a target copy pair to another storage area of the second storage system; transmits the change information to the first storage system that has a copy source storage area in the target copy pair; and transmits copy information for the purpose of copying data between the pre-change and post-change copy destination storage areas. The first storage system refers to pair information identifying the copy pair, and transmits a copy of the data stored in a copy source storage area to the second storage system that has a copy destination storage area. The first storage system updates the pair information according to the change information received from the second storage system.

摘要： Related plural logical volumes can be used after switching over from the host computer therein. A switching command, which a host computer sends, makes a storage device search for a switching target volume, from the volume tables, that is identical to identification information of the switching target volume received among switching target candidate volumes that form a volume pair relation with the switching source volume. The storage device memorizes an intra-host ID of the switching target volume and an intra-storage ID of the switching target volume in a switching table with a correspondence there between. The storage device acquires the intra-storage ID of the switching target volume in reference to the switching table in the case of receiving an access request, such that the intra-host ID of the switching source volume is used as a key, and executes switching to access to the switching target volume.

摘要： The identification information about unnecessary files is registered to generate an unnecessary-file database. The identification information about files stored on a plurality of storage devices connected to a host computer is acquired to judge with the unnecessary-file database whether the identification information about files conforms to unnecessary-file conditions. Files nonconforming to the unnecessary-file conditions are checked to determine whether they are already migrated to a different storage device. If all the files stored on a storage device conform to the unnecessary-file conditions or are already migrated to a different storage device, the identification information about the former storage device is displayed to indicate that the storage device can be removed.

摘要： To set access limitation, which limits access to a remote volume, to each host computer separately without registering in advance information on which volume is accessible to which host computer. In the storage system, the storage system is coupled to other storage systems in multiple stages, the uppermost stage storage system is coupled to the host computer, the volume constitutes a remote copy pair with a volume in the lower stage storage system and/or a remote copy pair with a volume in the upper stage storage system, and upon receiving a command to operate the volume, a control unit refers to pair information stored in a memory to judge whether information of the lower stage volume paired with the volume in the storage system that has this control unit is added to the received command.
