Port list
Displays information about the ports and paths of the local array or external array, depending on the item
selected in the Port tree. You can sort the list by displayed items. For instance, to sort the items by the port
number, select Port on the list.
Figure 34 Port list (External selected in Port tree)
The displayed contents changes depending on the item selected in the Port tree.
• Subsystem
When selected, displays nothing in the Port tree. Subsystem is selected when you initially display the
Port tree.
• External
• Port: Port of the local array with the port attribute is set to External. One of the following icons
appears for each port:
• Path: Number of set paths.
• FLI_TOV: Wait time (in seconds) from the switch to FLOGI when the switch is connected. External
Storage XP automatically sets this value. You cannot change the value.
• PLI_TOV: Wait time (in seconds) of PLOGI to the external array when the switch is not connected.
External Storage XP automatically sets this value. You cannot change the value.
• Margin: Additional wait time (in seconds) to FLI_TOV (FLOGI wait time) or PLI_TOV (PLOGI wait
time). External Storage XP automatically sets this value. You cannot change the value. As a result,
the sum of the FLI_TOV time and margin time, or the sum of the PLI_TOV time and margin time is set
as a total wait time.
• Status: Status of the path set in the port identified by the WWN. The highest emergency level status
is displayed when two or more paths are set. One of the following statuses is displayed:
• Normal: Path is normal.
• Unknown: Path status is unknown.
• Blockade: Path is blocked.
• Disconnect: Connection to the external array or external LU was intentionally stopped using the
Disconnect Subsystem ore Disconnect Volume command.
• Warning: There are paths whose status is not normal. Check the status of the paths.
• Checking: Process of checking the defined configuration information of the paths is in progress.
• Port number of the local array
