Configuring Cross-subsystem Path
You can configure the cross-subsystem path using the Configure Cross-subsystem Paths dialog box. This
section explains the procedure to add a cross-subsystem path to an existing path group. To create a new
path group and configure cross-subsystem paths, you need to operate the mapping operation. For the
procedure, see “ Mapping an External Volume Automatically ” on page 69.
To add the cross-subsystem path to an existing path group:
1. Start Remote Web Console, and open the Volume Operation window.
2. Make sure that Remote Web Console is in Modify mode.
3. Click the path group that you want to add a cross-subsystem path in the Volume Operation tree.
4. Right-click the cross-subsystem path in Cross-subsystem Paths in the Volume Operation list.
A pop-up menu is displayed.
5. Click Configure Cross-subsystem Paths in the pop-up menu.
The Configure Cross-subsystem Paths dialog box is displayed (see
“ Configure Cross-subsystem Paths Dialog Box ” on page 78).
6. In the Available Paths, click the following three items, and then right-click the WWN in the
WWN (see Figure 41 on page 82).
• External storage system: Click the external storage system.
• Port: Click the external port of the local storage system which is the starting point of the
cross-subsystem path.
• WWN: Click the WWN of the external storage system which is the ending point of the
cross-subsystem path.
Note: When the external storage system or the WWN that you want to choose is not displayed
in the dialog box, you can update the information by clicking the Port Discovery button, selecting
the port which connects to the WWN, and then clicking OK.
A pop-up menu is displayed.
7. Click Add in the pop-up menu.
The cross-subsystem path is added to the Selected Paths with the selected information. Configure
more than two cross-subsystem paths for one path group. Change the priority or delete
unnecessary cross-subsystem paths if necessary.
8. Click OK to close the Configure Cross-subsystem Paths dialog box.
You are returned to the Volume Operation window. The settings are displayed in blue and italics.
9. Verify the settings in the Preview dialog box (see “ Preview Dialog Box ” on page 57).
10. Click Apply in the Volume Operation window.
The settings are applied to the local storage system and the Volume Operation window is
displayed normally. When an error occurs, an error message is displayed. Verify the details
in the Preview dialog box.
