摘要： A method to provide resiliency with a destination volume in a replication environment is disclosed. Data from a source volume, such as a primary volume or a secondary volume in a replication relationship, is migrated to the destination volume. A snapshot representing data on a source volume is generated. The replication relationship between the source volumes is broken, and a new relationship between a source volume and the destination volume is established. A delta of data between the snapshot and one of the volumes in the new relationship is generated. The delta is sent to the other of the volumes in the new relationship.

摘要： A method is provided for a destination storage system to join a storage area network with a source storage system. The method includes discovering a volume on the source storage system when the source storage system exports the volume to the destination storage system and exporting the volume to the host computer systems. When a command to reserve the volume for a host computer system is received, the method includes determining locally if the volume is already reserved. When the volume is not already reserved, the method includes reserving locally the volume for the host computer system and transmitting to the source storage system another command to reserve the volume for the destination storage system.

摘要： A method for migrating data in a storage system includes generating a first set of logical disks (LDs), the LDs being mapped to physical storage space in the storage system, generating a temporary virtual volume (VV) mapped to the first set of LDs, generating a second set of LDs mapped to the temporary VV, and migrating data between the second set of LDs and a third set of LDs.

摘要： A method is provided for a destination storage system to handle SCSI-3 reservations. The method includes discovering a volume on a source storage system when the source storage system exports the volume to the destination storage system, exporting the volume to host computer systems, locally registering keys for first paths to the destination storage system, and registering with the source storage system the keys for second paths to the source storage system. When one of the host computer systems requests to reserve the volume, the method includes locally reserving the volume for paths to the destination storage system with registered keys and performing reservation forwarding to request the source storage system to reserve the volume for paths to the source storage system with registered keys.

摘要： One embodiment of the present invention provides a system that facilitates assigning an identifier to a device within a distributed computing system, wherein the identifier is unique across the distributed computing system. The system operates by detecting the presence of the device within a local computer system within the distributed computing system. If an identifier has not been assigned to the device, the system assigns an identifier to the device by, attempting to retrieve the identifier from a local pool of device identifiers within the local computer system. If the local pool is empty, the system retrieves at least one additional identifier for the local pool from a global allocator for device identifiers located within the distributed computing system. Next, the system assigns the retrieved identifier to the device so that the identifier can be used to reference the device.

摘要： A system for reducing network traffic for remote file system accesses receives requests at a local computer system for access to a file on the remote server. If the request is a read operation, and the operation is directed to an unallocated region of the file on the remote server, the system returns a block of null values to the requestor without receiving the block of null values from the remote server. Otherwise, the system sends a request to the remote server to read from the file. If the request is a write operation, and the operation is directed to an unallocated region of the file on the remote server, the system sends a request to the remote server to allocate storage for the write operation. Next, the system writes the data into a local cache. Later, the system copies the data from the cache to the remote storage.
摘要翻译： 用于减少用于远程文件系统访问的网络流量的系统在本地计算机系统处接收对远程服务器上的文件的访问的请求。 如果请求是读取操作，并且操作被引导到远程服务器上的文件的未分配区域，则系统向请求者返回一个空值块，而不从远程服务器接收到空值块。 否则，系统向远程服务器发送请求以从文件中读取。 如果请求是写入操作，并且操作被引导到远程服务器上的文件的未分配区域，则系统向远程服务器发送请求以分配写入操作的存储。 接下来，系统将数据写入本地缓存。 之后，系统将数据从缓存复制到远程存储。
