Monitoring and Managing the Switch
Port 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. To use this
option, follow the detailed steps in the hp StorageWorks edge switch 2/32 service
manual.
Channel Wrap (S/390 mode only)
Click this while in S/390 mode 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
Switch port, then the Switch echoes the frames back to the sending device to test the
channel. The Switch 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 will
appear to be blocked to all other communication. Click the check box to remove the
check mark and disable channel wrap.
Swap Ports (S/390 mode only)
Click this while in S/390 mode to display the Swap Ports dialog box. Use this dialog
box to swap addresses between ports. For details, refer to Swap Ports on page 5–1.
Clear Link Incident Alert(s)
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 alert 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 online, this operation sends a link reset to
the attached Switch, otherwise this action disables port beaconing for the port. 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.
