As conditions change, you can create new paths or delete selected paths on a LUN path basis that
are established between multiple host bus adapters (HBA) of a host within a host group. For example,
some HBAs may become unnecessary when the related applications are unneeded or infrequently
used, and you can delete selected LUN paths for such cases.
Prerequisites
Tasks to complete beforehand:
• Allocate volumes to the existing hosts.
1. On the Resources tab, expand the tree for storage systems, hosts, or logical groups to display
volumes.
2. Select one or more volumes for which you want to edit LUN paths. If selecting multiple volumes,
they must belong to the same configuration host group.
3. In the selected volume, click More Actions, and select Edit LUN Paths.
4. In the Edit LUN Paths dialog box, use the topographical graph or selection table view to map
storage ports to host ports. In both views, you can use links to view WWN nickname information
to confirm the target HBA.
1. In Topological Graph (or graph view), click on a storage port row to add it to the LUN Path
Editor panel. Connect the line to the target HBA. Another line is displayed, which you can
connect to another HBA or discard with a click.
2. In Selection Table (or table view), first select a storage port, then select a host port row, and
click Add to move the mapping to Selected host Ports list.
If you add an incorrect mapping and want to delete it, click the connector line in graph view, or
use the remove button in table view, or click Cancel to close the dialog box and start over.
5. To delete an existing path, which is indicated by a green line in graph view, or by the 'In Use'
state in the Selected host ports list in Selection Table, do the following:
TIP:
To delete all the LUN paths between a specific volume and a host so that there are no paths
left, delete LUN path settings by unallocating the volumes.
1. In graph view, click the green line. The line will now be gray and thin which indicates that
the LUN path is removed.
2. In table view, select the mapping row and click Remove to change the state from 'In Use' to
'Remove.'
6. Change any other required settings.
7. Click Show Plan and confirm that the information in the plan summary is correct.
Optionally, update the task name and provide a description.
8. Expand Schedule to specify the task schedule.
The task can be run immediately or scheduled for later. The default setting is Now.
9. Click Submit.
If you selected Now, the editing LUN path process begins
10. You can check the progress and result of the editing LUN paths task on the Tasks & Alerts tab.
Verify the results for each task by viewing the details of the task.
