Overview of Remote Command Devices

A remote command device is a device in the local storage system to which a command device in the external storage system is mapped.

As you send the RAID Manager commands to the remote command device, you can enter these RAID Manager commands to the command device of the external storage system to operate the RAID Manager in the external storage system.

Figure 41 (page 119) shows an example. The OPEN host that is connected to the local storage system sends the RAID Manager commands of XP Business Copy or XP Continuous Access to the remote command device, and this means that the commands are entered to the command device in the external storage system to operate the XP Business Copy pair or the XP Continuous Access pair in the external storage system.

For detailed information about RAID Manager and the command device, see the HP StorageWorks XP RAID Manager User Guide.
