7 Remote command devices
This chapter describes remote command devices.
Overview of remote command devices
A remote command device is a device in the local array to which a command device in the external
array is mappe
d.
As you send RAID Manager XP commands to a remote command device located in the local array, you
can execute those commands on the external array's command device to manage pairs in the external
array.
Figure 66 shows an example. The OPEN host connected to the local array sends RAID Manager XP
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 array to operate Business Copy XP or
Continuous A
ccess XP pairs in the external array.
For more information about RAID Manager XP and command devices, see the HP StorageWorks RAID
Manager XP User's Guide.
