Mapping command devices as remote command devices
To map command devices in external disk arrays as remote command devices, see ” Mapping external
LUs ” on page 45.
NOTE: Command devices that can be mapped as remote command devices are displayed on External
Storage XP’s panes as shown in Table 7 .
When you select Discovery in the Device Tree on the LU Operation pane, the external disk array’s WWNs
appear. When you select an external disk array’s WWN in the Device Tree, information such as
OPEN-V-CM appears in the Device column of the Device List for command devices that can be mapped.
Select a command device that can be mapped, and follow the procedure in ” Mapping external LUs ” on
page 45 to map it.

Table 9 General External Storage XP troubleshooting
Error Corrective action
The Command View XP
management station or XP
Remote Web Console cannot
access the external LU.
Correct the error and retry the operation.
The reason for the error could be one of the following:
• The Fibre Channel switch is off or an error occurred in the switch.
• The FC cables are not properly connected.
• The configuration of the external disk array changed, and the external LU has
been deleted.
• An error occurred with the external LU in the external disk array.
• The path between the local disk array and external disk array was changed.
• The port attribute of the local disk array is no longer external.
• The topology information is not set correctly.
If none of these are the problem, disconnect the cable between the local disk
array and external disk array, and reconnect it. Retry the operation after
30 seconds.
