Outline of remote command devices
A remote command device is a device in the local disk array to which a command device in the external
disk array is mapped.
As you send RAID Manager commands to a remote command device located in the local disk array, you
can execute those commands on the external disk array’s command device to manage pairs in the external
disk array.
Figure 48 shows an example. The OPEN host connected to the local disk array sends RAID Manager
commands for Business Copy XP or Continuous Access XP to the remote command device. This means
commands are forwarded to the command device in the external disk array to operate Business Copy XP
or Continuous Access XP pairs in the external disk array.
For more information about RAID Manager and command devices, see the HP StorageWorks RAID
Manager XP User’s Guide.
