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