4.2.6 Changing the Path Status
The procedure for changing the path status differs depending on the display format of the
path information. Path information can be displayed in the following two formats:
 Configuration-diagram format. This format uses a diagram to display the configuration of
the host, host bus adapters, paths, channel adapters, LUs, and storage system.
 List format. This format displays path information in a list.
You can switch the display format for the path information by clicking the Configuration tab
or the Path List tab.
4.2.6.1 Changing the Path Status from the Configuration Diagram
To change the path status when path information is displayed in configuration-diagram
format:
1. Display the Path Management window. The Path List view of the Path Management
window is displayed. (For details on displaying the Path Management window, see
section
4.2.2.1.)
2. Click the Configuration tab.
The Configuration view is displayed in the view frame.
3. In the tree frame, select the storage system or the LU connected to the path whose
status you want to change. If a storage system is selected, information on the paths that
connect the host and the selected storage system is displayed as a diagram in the view
frame. If an LU is selected, information on the paths that connect the host and the
selected LU is displayed as a diagram in the view frame. Note that the paths to be
displayed in the Configuration view can be restricted or expanded using the Type and
Status check boxes in the view frame. For details on the tree frame, see section
6.2.2.
For details on the Configuration view in the view frame, see section
6.2.3.
4. Select the path whose status you want to change. The line of the selected path will
become thick. You can select a path by any of the following three actions:
– Click the path. The selected path will become the target of operations.
– Click the CHA button. All paths connected to the channel adapter that corresponds
to the clicked CHA button will become the targets of operations.
– Click the button for the HBA port. The path connected to the HBA port that
corresponds to the clicked HBA port will become the targets of operations.
4. If you want to change the status of the selected path to online, click the Online button.
If you want to change the status to offline, click the Offline button. A dialog box
confirming that you want to change the status is displayed.
5. Click the OK button. The status of the selected path changes, and the line indicating the
path status changes also. For details on displaying the path, see section
6.2.3.
If you click the Online button without first selecting a path, in the Path List view all the
paths whose statuses are not Online will change to Online. Also note that if no path is
selected, the Offline button will be displayed as inactive, and will not function.
