HP StorageWorks External Storage XP user guide (T1706-96006, June 2006)

72 Configuring external LUs
6. Use the Add LU or Auto Map Settings pane to map the external LU as an internal LDEV (”Mapping
external LUs (Add LU)” on page 73).
7. If you select a mainframe emulation type on the Add LU pane, use Volume Manager to reformat the
volume or perform the Write to Control Blocks operation. For instructions, (see the HP StorageWorks
LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200.
8. Define alternate paths between the external array or mapped LU and the local array. For instructions,
see ”Defining alternate paths” on page 89.
9. Use LUN Manager to define paths. For instructions, see the HP StorageWorks LUN Configuration and
Security Manager XP user guide for the XP12000/XP10000/SVS200.
Setting an external array’s port
This section describes the procedure for setting the external array’s port. For more information, see the
external array’s documentation.
1. Set the topology information for the connection configuration.
2. Set the data transfer speed for the configuration.
3. Set the system parameters. For more information about system parameters for specific external arrays,
see ”Notes on connecting external arrays” on page 127.
4. Define the port’s LUN.
Setting a local array’s port attributes
The attribute of any port used for External Storage XP must be set to External.
NOTE: Only ports in SLPR0 can be set as external ports.
1. Select the Port Operation tab.
2. In the Port Operation list, select the port.
To set multiple ports at one time to External, select all the ports.
3. Right-click, and select Change to External.
In the Port Operation list, the selected port’s attribute changes to External, and the selected port’s row
appears in blue italics. Rows to be affected appear in the Preset list. To check setting details, right-click
the setting in the Preset list, and select Detail. To cancel settings, right-click the setting in the Preset list,
and select Delete.
4. Click Apply. A confirmation message appears.
5. Click OK. The port attribute setting is applied to the local array, and the new setting appears in the Port
Operation list.
If an error occurs, the failed setting and an error code appears in the Preset list. To view error
messages, right-click the failed row, and select Detail.
6. Set the topology for the connection configuration.
When an FC switch is connected, set Fabric to Enable. When a switch is not connected, set Fabric to
Disable, and specify FC-AL. Set Connection according to the actual connection configuration. For more
information about setting the topology, see the HP StorageWorks LUN Configuration and Security
Manager XP user guide for the XP12000/XP10000/SVS200.
7. Set the data transfer speed to Auto Negotiation.
NOTE: When connecting to a TagmaStore AMS or TagmaStore WMS subsystem, use LUN
Manager to set the data transfer speed of the XP12000/XP10000/SVS200 external port you use
to a fixed value other than Auto Negotiation. Also, set the data transfer speed of the target port of
the TagmaStore AMS or TagmaStore WMS subsystem to the same fixed value according to the
external port’s data transfer speed.
