92 Configuring external LUs
NOTE: Use the Add Paths window to add paths to multiple external LUs at one time. However, path
settings might not be applied because of the current path setting of each volume. After setting paths in the
Add Paths window, check whether or not the new path settings can be applied in the Path Setting window
for each external LU. If the setting cannot be applied, the setting from the Add Paths window does not
appear on the Path Setting window. The setting from the Add Paths window also does not appear in the
Preset list or in the LU Operation pane.
Figure 53 Add Paths window
• Port
Local array ports. After selecting a port, you can add paths. One of the following icons appears for
each port:
• Selected Paths
Paths that are added as ports that configure alternate paths. WWNs identify ports on the external
array. Nothing is displayed when you initially access the Add Paths window.
• Unselected Paths
External array ports (WWNs) that can configure the path connecting with the local array port selected
in the Port list. Select WWNs from this list to add as alternate paths.
• Set
Moves WWNs selected in Unselected Paths to Selected Paths.
• Release
Moves WWNs selected in Selected Paths to Unselected Paths.
• OK
Saves settings in the Add Paths window, closes the Add Paths window, and displays the Path Setting
window.
• Cancel
Cancels all settings in the Add Paths window, and closes the window.
To add alternate paths to multiple external LUs at one time:
1. Select the LU Operation tab. The LU Operation pane appears.
2. In the Device tree, select an external LU group number. Information about external LUs mapped as
internal LDEVs appears in the Device list.
3. In the Device list, select multiple external LUs, right-click, and select Add Paths. The Add Paths window
appears.
