director product manager user guide
Configuring the Director
enables the port to process 2K frames from attached devices. If this option is not
enabled, the port uses the BB_Credit (1–60) configured through the Operating
Parameters dialog box.
If a device is connected and logged in to the fabric when extended distance is
enabled or disabled on the corresponding port, the switch will send OLS for 5 ms
to force the device to log in again and obtain the new BB_Credit value set for the
port.

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 Product 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 (refer to
Figure 2–11 on page 2-17
).
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 Product
Manager’s Maintenance menu.
For additional information about LIN alerts, refer to “
Link Incident Alerts

Type—Choose each port’s type (G_Port, E_Port, or F_Port) in this column from
the drop-down list.
NOTE: In S/390 mode, you cannot change port types unless the optional SANtegrity
feature is installed. If ports are configured as E_Ports in Open Systems mode, and you
install SANtegrity before changing to S/390 mode, the ports will remain as E_Ports when
you change to S/390 mode. If SANtegrity is not installed, setting a director to S/390 mode
will change all E_ports to G_Ports.
