Configuring iSCSI Driver Options
The following table lists the user configurable iSCSI driver options. It includes a
description of the parameters, default values, and the limits within which they can be
configured.
Note: If the value given for a parameter is outside the supported range (Minimum and
Maximum values), then the driver will log an error in the Event Log and
continue to load using the default value of the parameter.
The following command line shows how to configure the driver with LDTO value as 25
seconds:
# vmkload_mod be2iscsi ldto=25
