DELAY_TOUT

Minimum value = 0, maximum value = 500 (decimal). Default = 0;

This parameter specifies a delay period to extend the timeout value of operations (such

as read or write to a target device). This allows, for instance, an adjustment in timeouts

when large fabrics or WAN−connected fabrics may add delays to normal response

times. The default value is appropriate for most environments, and care should be used

in choosing any non−zero value.

LINK_SPEED

Minimum value = 0, maximum value = 2. Default = 0;

This parameter controls the setting of the Fibre Channel link speed in HBAs capable of

2 Gbps link speeds. The value 0 selects auto−negotiate; the HBA attempts to match

the link speed of the other devices on the link. The value 1 forces the HBA to use 1

Gbps link speed. The value 2 forces the HBA to use 2 Gbps link speed. The default

value of 0 is appropriate for most environments.

TOPOLOGY

Accepted values = 0, 1, 2, or 3. Default = 2;

Topology specifies the type of link to be supported.

0 to specify loop topology,

1 to specify point−to−point topology (including switched fabric),

2 to attempt to use loop first, then point−to−point if loop is not found,

3 to attempt to point−to−point first, then loop if point−to−point is not found.

NOTE: If the actual setup is private loop using a hub product (for example, Emulex

LH5000) and topology option 3 is used to attempt point−to−point first with fail−over to

loop, be sure that the AutoLIP feature (LIP 57 on insert) is enabled.

USEADISC

Boolean parameter: 0 = not selected, 1 = selected. Default is USEADISC=0;.

USEADISC is used in link error recovery situations (link up events). If set to 0 (default),

only PLOGI is used. If set to 1, uses ADISC when possible to rediscover a node.
