entered from open-system hosts. When the administrator enters an RAID Manager command from
an open-system host, the RAID Manager command is transferred via the command device to the
target logical device.
To protect a logical device from RAID Manager commands, you must apply command device
security to the logical device. If command device security is applied to a logical device, the device
will not be affected by RAID Manager commands even when commands are transferred via a
command device to that device.
For details, see “Configuring the Storage System for Using RAID Manager” (page 84).
You cannot use the following volumes as command devices:
• Volumes that do not have Read/Write access attribute
• Volumes reserved by XP Auto LUN. For more information, see HP StorageWorks
XP24000/XP20000 Auto LUN Software User Guide.
