[Veritas-bu] Gigabit Cards

If the auto negotiate does not work, then the 100-MB full-duplex mode
can be forced to run at 100-MB, Full-Duplex using the following:
When forcing one side of the link, it is important to force both sides.
The speed and mode on the link partner( switch or hub) must be set to match.
or link down, excessive/late collisions and ierrors will result.

Please try (if using /etc/rc2.d/S99...)

        ndd -set /dev/hme instance 0
        ndd -set /dev/hme adv_100T4_cap 0
        ndd -set /dev/hme adv_100fdx_cap 1
        ndd -set /dev/hme adv_100hdx_cap 0
        ndd -set /dev/hme adv_10fdx_cap 0
        ndd -set /dev/hme adv_10hdx_cap 0
        ndd -set /dev/hme adv_autoneg_cap 0

        or (if using /etc/system)

        set hme:hme_adv_autoneg_cap=0
        set hme:hme_adv_100T4_cap=0
        set hme:hme_adv_100fdx_cap=1
        set hme:hme_adv_100hdx_cap=0
        set hme:hme_adv_10fdx_cap=0
        set hme:hme_adv_10hdx_cap=0

Apparently, the order in which the commands are executed can
make a difference. The link is re-negotiated when the interface is
ifconfig'ed up or when ndd ndd adv_autoneg_cap command is executed.

Note: If you add commands to /etc/system file, you must reboot

We are running to SUN Servers E4500 with two gigibit cards in each server. 
One
is a master and the other is a slave. Currently the cards are set to
auto-negotiate. Does anyone know what the settings would be to force tmen to
full? We tried these settings from Veritas but they did not work.

Thanks

First we tried a regular boot:
-----------------------------

We also tried a reconfiguration boot (boot -r):
---------------------------------------------------------------------

In both cases auto-negotiation was clearly still being used:
