Remove lan0 network card and install quadport network card

[Daniel Comtois_1]

Hi everyone,

Because I never do that before, can one of you can give me the right procedure for removing properly the onboard network card without any errors, because we need to install a new QuadPort network card on a HP VisualizeC360 server with HP-UX 10.20 to give more bandwith to users of our CAD Dept? That new card come with his own drivers and software.

Also, in case of a any problem with the new card installation, how to go back to previous onboard network card?

Thanks,

Use SAM and disable the onboard network card. Then add your new card, install drivers and configure through SAM.
I think this is easiest way.

Hi Daniel, you can find installation guides here:

Given more bandwidth to your CAD users with a quiadport card on 10.20 may be, well, interesting...

IIRC, the LAN monitor stuff available on 10.20 is strictly for failover, and does not offer active/active link aggregatation.

Assuming my recollection is correct (it may be incorrect) that means you will have to ifconfig each of the four ports on the card with their own IP address.

And since HP-UX 10.20 does not particularly like having different physical interfaces (each port on that card is a different physical interface) configured into the same IP subnet you will need to configure each port into a separate IP subnet, and that may require some reworking of your network.

Even if the LAN Monitor/trunking software on 10.20 does allow for some active active aggregatation, keep in mind that any one flow (TCP connection) will still go no faster than a 100BT link - one cannot split a single flow across multiple interfaces).

If you need an _individual_ flow to go faster than 100BT, you will need to switch to Gigabit Ethernet.

Also, in terms of setting expectations, keep in mind that neither the quad port card, nor a gigabit ethernet interface does much to make data transfer easier on the host, so if you are presently running at say 50% CPU utilization, you will not increase thruoghput by more than another 100 megabits/s no matter what.
