How to use the SP switch

[nAtHaNs]

Hello Gurus,

We have a SAP application with an Informix database running on SP. Our problem is that when SAP and informix were installed, the SP LAN was the one configured for the Node to Node communication not the SP switch. How do we reconfigure it so as to make use of our SP switch? Which is the easier approach, application or the SP reconfiguration?

Thanks.

Hi,
you can manage this with static routes.

For example on SAP Appl. Server
route add <informix_lan> <informix_switch>

and on Informix Server
route add <sap_lan> <sap_switch>

But better set the routes via smitty to make them survive the next reboot.

If hosts outside the SP switch network need to contact the switch nodes in the SP, they must have a route to the switch network through one of the SP nodes, preferably the SP swich router.

If you want to assign IP addresses freely to the switch as you do with other adapters, you must enable ARP for the css0 adapter.

It would probably be easier to change the application than the switch if you don't have a lot of knowledge of PSSP and the switch and SP system.
