Hi Tobias, This is not an answer exactly more of a question..... If you have two OSA cards why would you want to use VSWITCH High Availability rather than a full network High Availability solution?
What I mean is why not use two VSWITCHes each connected to its own OSA in a standard manner, and use a routing protocol such as OSPF (For Linux that's Quagga/Zebra) to handle network path outages. That is typically what we use for SAP R/3 environments. A solution such as OSPF also opens up possibilities such as workload balancing over multiple paths etc. All the Best Mark Perry > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of > Tobias Doerkes > Sent: 15 December 2004 11:09 > To: [EMAIL PROTECTED] > Subject: Using VSWITCH and OSA > > Hi list, > > we want to start using VSWITCH with external connection via OSA.
