Actions
There are several actions that can be performed by the diagnostic application.
•
Display worldwide port and node names (WWNs).
•
Refresh failover drivers’ state information held by the diagnostic application.
•
Request current failover information from tape and changer devices.
•
Clear reservations on changer devices which had been set by hosts that are now offline.
Display worldwide port and node names (WWNs)
Port and node worldwide names are only shown in the Devices and Paths panes when the Show
WWN menu item is selected, as shown below. Display of worldwide names is optional because
some host bus adapters can take up to thirty seconds to respond to a request for a WWN. When
there are many devices, this can lead to long delays in refreshing the screen.
