摘要： In one aspect of the invention, A data center system comprises a plurality of data centers each including a computer and a storage system. The computers each include a memory area for storing information about an order of operating priorities among the computers and another memory area for storing a cluster service program, whereby when an active computer from the computers fails as a failed computer, the cluster service program is executed to select a standby computer from the remaining computers according to the information about the order of operating priorities to be a failover computer to take over processing from the failed computer. The information about the order of operating priorities may relate to the types of remote copy operation used between the storage systems.

摘要： An object of remote copy can be specified in units of a file or a directory more detailed than in units of a volume. If a host computer issues a write request of a file to NASa, NASa references a source NAS of remote copy and a source directory of remote copy at each entry on a copy file table and determines whether the file to be written is an object of remote copy; if it is determined to be an object of remote copy, the file to be written is remotely copied to a target directory of remote copy of a target NAS thereof.

摘要： Inconveniences such as a manager erroneously deleting data in the secondary volume, or deleting the setting itself of the secondary volume in an SLPR storage system can be prevented. All LDEV information regarding all SLPR managed by a manager is acquired (S171). The user ID and password of the SLPR management table for secondary LDEV are designated, the SLPR for secondary LDEV is designated for the SLPR number, and notified to the maintenance terminal (S172). All LDEV information of all SLPR is displayed as a list (S173). Primary LDEV is selected from a pair management table (S174). Whether the manager is an SLPR manager for secondary LDEV, subsystem manager, or SLPR manager is checked (S175). Those having the same size and RAID level as the primary LDEV are displayed as a list (S176). The secondary LDEV is selected (S177), a local replication pair generation command is issued with the user ID and password of the subsystem manager from the secondary LDEV and primary LDEV, and a pair of the primary LDEV and secondary LDEV is created (S179).

摘要： An object of the present invention is to improve the usage efficiency of a storage extent in a storage system using the AOU technique. A controller in the storage system allocates a storage extent in an actual volume to an extent in a virtual volume accessed by a host computer, detects any decrease in necessity for maintaining that allocation, and cancels the allocation of the storage extent in the actual volume to the extent in the virtual volume based on the detection result.
