By clicking the Route Search Execution icon on the toolbar on the Correlation window while selecting a device icon or element, this displays all of the correlated device icons, element icons, and links in distinct colors. A device icon or element selected is displayed in different colors from the corelated device icons, element icons, and link. Clicking the Route Search Clearance icon on the on the toolbar clears the route. The following shows examples of the operation:
The upper figure above shows a Correlation window displayed after the Route Search Execution icon on the toolbar is clicked. The lower figure above shows a Correlation window displayed after the Route Search Clearance icon on the toolbar is clicked. Even if the device icon display is changed to the device detailed information display, an integration icon is changed to a table element, or a layer is added with the show element function, the display of the route can be kept up. The following shows examples of operation.
The upper figure above shows a Correlation window displayed after a table is selected from table elements for Logical Volume of storage and the Route Search Execution icon on the toolbar is clicked. The lower figure above shows a Correlation window displayed after an LUN integration icon of storage is displayed as a table element. As shown in the figure, since route search is still effective, simply expanding the LUN integration icon into a table element provides information on LUN correlations. The following explains these features using some operation examples.
[Check all the disk related to a certain application]
To determine the disk and storage that contains the disk area used by the application, select the application and click the Route Search Execution icon from the toolbar in the Correlation window. A window opens to show the related element icons and links in the colors shown below. You can now easily determine which disk of which storage is being used.
Note
In a Linux server node equipped with PG-FC 105 (driver version V4.20q.1), PG-FC 106 (driver version V4.20q.1), PG-FCD101 or PG-FCD102, you cannot determine the disk areas that are used by the application because routes beyond the HBA port cannot be searched.
[Checking the multipath configuration]
To determine a multi-path configuration, select a multi-path driver element and click the Route Search Execution icon from the toolbar in the Correlation window. A window opens to show the related element icons and links in the colors shown below. You can now easily determine which path and route are being used.
Note
In a Linux server node equipped with PG-FC 105 (driver version V4.20q.1), PG-FC 106 (driver version V4.20q.1), PG-FCD101 or PG-FCD102, you cannot determine the multi-path configuration beyond the HBA port because routes beyond the HBA port cannot be searched.
[Check all the applications related to a certain disk]
To determine the application of the server node using the disk, select a disk element and click the Route Search Execution icon from the toolbar in the Correlation window. A window opens to show the related element icons and links in the colors shown below. You can now easily determine which application of which server node uses the disk.
Note
In a Linux server node equipped with PG-FC 105 (driver version V4.20q.1), PG-FC 106 (driver version V4.20q.1), PG-FCD101 or PG-FCD102, you cannot determine which application uses the disk because routes beyond the HBA port cannot be searched.
Note
When AffinityGroups are linked to ETERNUS8000, ETERNUS6000, ETERNUS4000, ETERNUS2000 or ETERNUS DX60/DX80, the AffinityGroup not used is not subject to a route search. Thus, the element icon of the AffinityGroup not used is not displayed in color. If a route search is executed by selecting the element icon of the AffinityGroup not used, only the specified icon is displayed in color.
