The MCU-RCU Path field includes:
•
MCU Port: MCU port number. The Initiator and RCP are listed in the drop-down list and can
be selected.
•
RCU Port: RCU port number. The RCU Target port must be specified.
•
Link Address: Link address (serial only). Destination port address on the ESCD (00-FD, 00 for
static link to RCU).
The Cancel button cancels settings made. The Set button applies settings made and changes the
list.
NOTE:
Maximum number of paths is eight. Each item has seven fields to enter paths, but you
cannot enter more than eight paths.
See
“Logical path status” (page 70)
for further information about path status.
Adding new logical paths from the connected MCU to an existing RCU:
Before adding a path to an RCU, ensure that the remote copy connection is properly installed,
appropriate MCU ports are configured as Initiator ports (fibre) or RCPs (serial), and appropriate
MCU CU image is selected. You can add up to four RCUs to each MCU CU image and establish
up to eight paths to each RCU. When you add a path to an RCU, XP Continuous Access
automatically starts using the new path to perform XP Continuous Access copy activities.
1.
From the CU Number/Port tree on the RCU Operation pane, ensure that the correct CU image
is selected.
2.
From the MCU/RCU list, click the RCU.
3.
Right-click, and click Edit SSID(s)&Path(s).
4.
Right-click, and click Add Path. The Add Path pane appears.
5.
Enter new paths. Each item has seven fields to enter, but you can only enter the number of
paths left (maximum number of paths is eight).
6.
Click Set to set the paths. The list changes to the Path Settings Parameter list.
NOTE:
After being set, options can be modified and canceled (see
and deleting settings” (page 81)
).
7.
Click Apply on the XP Continuous Access main pane to apply the settings to the disk array.
The MCU automatically begins using the new logical path for XP Continuous Access activities.
Deleting paths from the connected MCU to an existing RCU:
Before deleting a path to an RCU, ensure that remaining number of paths is equal to or greater
than minimum number of paths setting (selected on the RCU Option pane). The delete path operation
fails if number of remaining paths is less than minimum number of paths.
1.
Open the RCU Option pane, and check the minimum number of paths setting. If the remaining
number of paths is less than this value, the delete path operation will fail. If needed, change
the minimum number of paths so you can delete the path.
2.
From the CU Number/Port tree on the RCU Operation pane, ensure that the correct CU image
is selected.
3.
From the MCU/RCU list, click the RCU from which you want to delete the path.
4.
Right-click, and click Edit SSID(s)&Path(s).
5.
Right-click, and click Delete Path. The list changes to the Path Settings Parameter list. Only
selected RCUs are listed.
