In this manual, the storage system that receives requests from the REST API clients is called a local storage system, and the storage system that is remotely connected to the local storage system is called a remote storage system.
The following figure shows an example of a remote connection:
- Remote path
-
A logical path that connects storage systems on the primary site and the secondary site is called a remote path.
A combination of port numbers that a logical path consists of is defined as a remote path.
- Remote connections
-
A remote connection consists of a group of remote paths that connect the storage system on the primary site (MCU) and the storage system on the secondary site (RCU).
A remote connection consists of one or more remote paths, and a unique path group ID is assigned to each remote connection for management.
To set a remote connection by using the copy direction from the remote storage system to the local storage system, specify settings from a REST API client of the remote storage system.
The following is a list of operations that can be performed for remote connections by using the REST API.
-
Create remote connections
-
Change remote connection settings
-
Add remote paths to remote connections
-
Delete remote paths from remote connections
-
Delete remote connections
-
Get information about remote connections
To create a remote path for an iSCSI port, register in advance information about the iSCSI port of the remote storage system to the iSCSI port of the local storage system.
The following is a list of operations that can be performed for iSCSI ports by using the REST API.
-
Register iSCSI ports
-
Delete iSCSI ports
-
Get information about iSCSI ports
