摘要： A computer system regarding which there is no possibility that data loss or data leakage will occur caused by volume migration is provided. The computer system includes: a memory resource to be accessed by a host computer; a storage system for providing a volume, which logicizes the memory resource, to the host computer; and a management device for managing migration of the volume. When detecting a task of migration of the volume based on a request from a first administrator, the management device compares an encryption function setting status of the volume with the encryption function setting status of a migration destination object of the volume; and sends notice of this comparison result to a second administrator, who is different from the first administrator, for security management of the storage system.

摘要： Resources migrated from migration source storage apparatuses to a migration destination storage apparatus are appropriately allocated to each migration source user. A migration destination storage apparatus among a plurality of storage apparatuses and has a controller for sending or receiving information to or from a host computer and managing each migration destination volume as an access target of the host computer. The controller manages each migration destination volume by dividing the migration destination volumes into a plurality of resource groups based on identification information for identifying each migration source volume; manages a plurality of resources related to each migration destination volume by associating them with each resource group; and manages each migration destination volume and each resource belonging to each resource group as operation targets to be allocated individually to each migration source user who uses each migration source volume, and as operation targets over which only each migration source user has operation authority.

摘要： The present invention provides a technique capable of preventing data loss due to relocation of physical storage devices. When a request to relocate a logical storage area is issued, it is determined if the logical storage area to be relocated, which is composed of the physical storage devices in the source storage apparatus, can be configured in the destination storage apparatus, and if it is, the physical storage devices that constitute the logical storage area to be relocated are switched into a write-inhibit state in the source storage apparatus, and the write-inhibit state of the physical storage devices is maintained until the physical storage devices are set up and the logical storage area to be relocated is configured in the destination storage apparatus.

摘要： The present invention makes it possible to reassess respective host paths and reset priorities in accordance with the current state of a storage system. A management computer 400, in a case where either a failure or a configuration change occurs inside the storage system, assesses the respective host paths 501 through 506 in accordance with the status of a first communication network 500 and the status of a second communication network 600. The management computer 400, based on these assessment results, resets the priority of each host path. An alternate path program 112 of the host 100 are notified of the priorities, which have been set.

摘要： When removing an HDD, in which a failure has occurred, after the execution of hot swap in a storage apparatus having a stored data encryption function, an encryption key assigned to that HDD is shredded and thereby data in the HDD is automatically crypto-shredded; and after a new HDD is installed, data in a spare disk regarding which copy back to the new HDD is completed is automatically crypto-shredded and key generation for the spare disk is requested to a security administrator in preparation for the next hot swap. Then, with the storage apparatus which imports and uses an encryption key generated by an external key management server for encryption/decoding of stored data, the encryption key for the spare disk is imported from the external key management server in advance and the encryption key is prevented from the use other than the intended use in preparation for a case where the encryption key may not be imported due to a communication failure with the external key management server at the time of the hot swap, thereby causing a shortage of encryption keys.
摘要翻译：当在具有存储的数据加密功能的存储装置中去除发生故障的HDD之后，分配给该HDD的加密密钥被切割，从而HDD中的数据被自动加密; 并且在安装了新的HDD之后，自动密码将关于哪个复制到新的HDD的备用磁盘的数据加密，并且向安全管理员请求备用磁盘的密钥生成以准备下一个热插拔。然后，在导入并使用由外部密钥管理服务器生成的加密密钥进行存储数据的加密/解码的加密密钥的存储装置中，预先从外部密钥管理服务器导入备用盘的加密密钥，加密密钥由于在热插拔时由于与外部密钥管理服务器的通信故障而导致加密密钥不能导入的情况，所以防止使用以外的使用，从而导致加密密钥短缺。
