The data display lists all available device driver parameters, along with the
current, minimum, maximum, and default values. Parameters that have their value
specified in the system registry are denoted with either a G or an L in the left-most
column of the screen. The G indicates that the value is set in the global registry
entry, which applies to all HBAs that do not have a local registry entry. The L
indicates that the value is set in a registry entry specific to the selected HBA,
which overrides the value settings in the global entry.

1. Choose the desired HBA.

Do not modify the registry parameters unless specifically instructed
to do so by support personnel. Modifying registry parameters can result in an
unstable SAN.
