Specifying logical devices as command devices – HP StorageWorks XP10000 Disk Array User Manual

Configuring arrays for using RAID Manager XP commands
The system administrator can enter RAID Manager XP commands from open-system hosts to perform
Continuous Access XP and Business Copy XP operations on logical devices. For example, use RAID
Manager XP commands to create and split pairs. To enable the system administrator to enter RAID
Manager XP commands from open-system hosts, you must specify at least one logical device as the
command device. If desired, you must also apply command device security to other logical devices in
the array.
NOTE:
If an array is divided into SLPRs and you want to prevent RAID Manager XP commands from affecting
multiple SLPRs, you must apply command device security to the logical volumes.
Specifying logical devices as command devices
To enable the system administrator to execute RAID Manager XP commands from an open-system host,
you must select at least one logical device that will not be manipulated by Continuous Access XP or
Business Copy XP, and then specify the devices as the command devices. When a RAID Manager XP
command is issued from a host, the command device receives the command. The command device
transfers the command to another logical device. Then, the command performs a Continuous Access XP
or Business Copy XP operation on that logical device.

Protecting logical devices from RAID Manager XP commands
To protect logical volumes from RAID Manager XP commands, you must apply command device security
to the logical volumes. If command device security is applied to a logical device, the logical device is not
affected by RAID Manager XP commands issued via command devices from hosts.
