Except for generic storage arrays, it is possible to delete additional access groups that you may have defined apart from the default access group.
To delete one or more access groups:
Expand the SAN Servers folder in the navigation tree, select a SAN server item contained within the folder. Select the Access Groups option in the Perspective drop-down list. Select the access group or groups, that you wish to delete, from the items listed in the management pane.
Click on the
Delete Access Group icon in
the toolbar.
The Delete Confirmation dialog box is displayed. Click OK to delete the access group.
