摘要： Provided is a method of managing a computer system including a plurality of storage systems and a plurality of management appliances for managing the plurality of storage systems. A first management appliance and a second management appliance hold an identifier of a first storage system and management data obtained from the first storage system. The method includes the steps of selecting a third management appliance from the plurality of management appliances when a failure occurs in the first management appliance; transmitting the identifier held in the second management appliance from the second management appliance to the selected third management appliance; and holding the identifier transmitted from the second management appliance in the selected third management appliance. Thus, it is possible to prevent, after failing-over due to an abnormality of a maintenance/management appliance, a single point of failure from occurring to reduce reliability of the maintenance/management appliance.

摘要： A secure data mirroring capability in a storage system includes encrypting data blocks in a primary volume in preparation for a data mirroring operation. The encrypted data blocks are mirrored to a secure secondary volume. Host systems provide keys from which encryption keys are produced for encrypting the data blocks. Access to data on the secure secondary volume requires decryption using the key that was used to produce the encrypted data blocks.

摘要： Described is a method for secure data disposal. Data stored in storage volume(s) is encrypted with a specific encryption key. Before the key is disposed of, a clear text string is encrypted with the same key and the encrypted data is associated with the clear text string and stored in a repository. When a new key is created to encrypt a new volume, each of the encrypted data in the repository is checked to determine whether the encryption of the associated clear text string using the new key generates the same encrypted string as the stored encrypted data. If the result of the encryption of the clear text string matches at least one stored encrypted string, the associated new key is not used and another key is generated until the new key results in an encrypted string which does not match any stored encrypted strings.
摘要翻译：描述了一种用于安全数据处理的方法。存储在存储卷中的数据用特定加密密钥加密。在处理密钥之前，使用相同的密钥对明文本字符串进行加密，并且加密数据与清除文本字符串相关联并存储在存储库中。当创建新密钥以加密新卷时，检查存储库中的每个加密数据以确定使用新密钥对相关联的明文字符串的加密是否生成与存储的加密数据相同的加密字符串。如果清除文本字符串的加密结果与至少一个存储的加密字符串相匹配，则不使用关联的新密钥，并且生成另一个密钥，直到新密钥产生与任何存储的加密字符串不匹配的加密字符串。
