Software User Manual

For the Port display, the menu commands are:
• Initiator: Allows you to change the selected fibre port(s) to initiator ports.
• RCU Target: Allows you to change the selected fibre port(s) to RCU targets.
• Target: Allows you to change the selected fibre port(s) to target ports.
For the MCU&RCU display, click the menu command for the desired operation. When two or
more RCUs are selected, only the RCU Operation command is available. For the add and
change operations, use the dialog box to perform the operation, and click Set to close the
dialog box. There is no dialog box for the delete operation.
The RCU Operation preview list displays the requested operation(s). To cancel the add or
change operation, click Cancel. For the Port display, select the desired port type
The RCU Operation preview list displays the requested port change operation(s).
5. Verify the specified RCU or port operation(s) in the preview list. Make changes as follows:
a. For the MCU & RCU display, to change an operation, select the desired operation (RCU,
path, or SSID), right-click it, click Modify, make the desired changes, and close the dialog
box. The preview list displays the updated information.
For the Port display, to change the port type, select the desired port, right-click, and select
the desired port type. The preview list displays the updated information.
b. To omit one or more operations, select the operation(s) to be omitted (RCU, path, SSID,
or port), right-click, and click Delete. The operations are removed from the preview list.
If all operations are removed, the list returns to its original display.
c. To cancel all operations, select all the operations in the preview list, right-click, and click
the Delete command, or click the Cancel button. All operations are removed, and the list
returns to its original display.
6. To start the operation(s), click the Apply button.
Configuring the Host Interface Ports
The XP Continuous Access software allows you to change the configuration of the storage system
host interface ports as needed to accommodate the desired host and XP Continuous Access
communications paths.
The storage system Fibre Channel interface ports can be configured as target ports (default), initiator
ports, or RCU target ports (see “Initiator Ports and RCU Target Ports” (page 15)).
The port assigned to an SLPR other than SLPR0 can be set to the Target port attribute only.
• Target: The Fibre Channel ports that will be connected to the host must be configured as target
ports (default). Target mode is used for the host processor channel interface.
• Initiator: The Fibre Channel ports that will be used for XP Continuous Access communications
to the RCUs must be configured as initiator ports. Initiator mode emulates a host channel to
enable the MCU to send write I/O operations directly to the RCU target port. Two or more
initiator ports must be configured before you can add the RCUs and create the XP Continuous
Access pairs.
• RCU target: The Fibre Channel ports in the RCU that will be used to communicate with the
MCUs must be configured as RCU target ports.
• External: This attribute can be set using HP XP External Storage Software. The external port
is used for External Storage, not XP Continuous Access. To use this port for XP Continuous
Access, change the attribute to the initiator, RCU target, or target port.
• Initiator/External: This setting shows the combination of ports that have initiator port and
external port attributes. Only the port that has an initiator port attribute within these ports can
be used for XP Continuous Access. This attribute cannot be changed using the XP Continuous
RCU Operations 83
