Director Element Manager user guide 99
• LIN Alerts—A link incident (LIN) is a problem detected on a fiber optic link, such as the loss of
light or invalid sequences. When a problem occurs, a LIN alert is sent to the Link Incident Log in
the switch Element Manager. LIN alerts warn you that there is a link incident being detected
through a port connection.
Place or remove check marks in the check boxes in this column to enable or disable link
incident alerts. The factory default is to enable LIN alerts.
A link incident causes a yellow attention indicator (triangle) to display for the port in the
Hardware view, Port Card view, and in the Alert column of the Port List view. Once a LIN
occurs, you must acknowledge it by choosing the Clear Link Incident Alert option from the
right-click menu for the port (Hardware view). A description of the alert displays in the Link
Incident field of the Port Properties dialog box (see Figure 23 on page 65).
If the check boxes in this column are not selected, no link incident indicators display in the
Hardware view. Also, the Link Incident field of the Port Properties dialog box is blank and a link
incident is recorded in the Link Incident Log. LINs are always logged in the Link Incident Log,
regardless of the configuration.
If LIN Alerts are enabled, you can receive e-mail notification when a LIN occurs. To receive
e-mail notification, you must configure and enable this feature in the Maintenance menu of the
StorageWorks HA-Fabric Manager (HAFM) and enable e-mail notification through the Enable
E-Mail Notification option in the Element Manager’s Maintenance menu.
For additional information about LIN alerts, see ”
Link incident alerts ” on page 87.
