Monitoring and Managing the Director

Diagnostics

Click this option to display the Port Diagnostics dialog box. Use this dialog box
to run an internal loopback and external loopback test on the port. The Port
Diagnostics option enables you to run internal and external loopback tests on any
port or all ports on a port card. To use this option, follow the detailed steps in the
HP StorageWorks Director 2/64 Service Manual.

Channel Wrap (FICON Management Style only)

Click this while in FICON management style to display a check mark and allow a
channel wrap test to be initiated from an attached host or device. In this test,
frames are sent to the director port, then the director echoes the frames back to the
sending device to test the channel. The director remains in channel wrap mode
until the option is disabled. While in channel wrap mode, the port can only accept
echo commands from the host and display as to be blocked to all other
communication. Click the check box to remove the check mark and disable
channel wrap.

Swap Ports (FICON Management Style only)

Click this while in FICON management style to display the Swap Ports dialog
box. Use this dialog box to swap addresses between ports.

Clear Link Incident Alerts

Click this to clear the attention indicator on the Hardware View, the Port List
View, and the Performance View. In addition, the procedure clears the status
description in Port Properties dialog boxes. If there are no link incident alerts set
for a port, no actions occur. Although you can manually clear link incidents, they
may also be cleared by actions outside of the user interface, such as when
rebooting the HAFM server.

Reset Port

Click to display a confirmation dialog box. Click Yes on that dialog box to reset
the port. If a switch is attached to the port and is online, this operation sends a link
reset to the attached switch; otherwise, this action disables port beaconing for the
port. And if the port is in a failed state, such as after failing a loopback test, the
reset restores the port to an operational state, clearing the service required (amber)
LED. The reset does not affect other ports in the switch.
