HP StorageWorks 2.64 Director Switch - Manual (Page 70)

Monitoring and managing the director 70
• Channel Wrap (FICON management style)—Click this option 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 displays 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 option while in FICON management
style to display the Swap Ports dialog box. Use this dialog box to swap addresses between
ports. For details, see ” Swap ports (FICON management style) ” on page 140.
• Clear Link Incident Alert(s)—Click this option on the port’s right-click menu on the Port Card
view and the Port List view to display the Clear Link Incident Alert(s) dialog box. Click This port
only to clear the attention indicator for the selected port on the Hardware view, the Port List
view, and the Performance view. Click All ports on director to clear all ports. 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 appliance.
• Reset Port—Click this option to display a confirmation dialog box. Click Yes 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 director.
• Port Binding—Right-click any port in the Port Card view right-click menu and select Port Binding
to display the Port Binding dialog box, as shown in Figure 24 on page 70. Use this dialog box
to allow a device with a specific WWN or nickname to have exclusive communication
privileges over a port. To use this dialog box, see the following paragraphs.
Figure 24 Port Binding dialog box
Use the Port Binding dialog box to set the following options:
• Port Binding—Click to place a check mark in the box and enable Port Binding for the port.
When enabled, only a specific device can communicate through the port. This device is
specified by the WWN or nickname entered into the Bound WWN field (either the Attached
WWN or Detached WWN options). With the check box cleared, any device can
communicate through the port even if a WWN or nickname is specified in the Bound WWN
field.
