IP Redundancy on 7200's with CPA's

I have 2 7206's with CPA cards Escon attached to an IBM host. I'm trying to get IP failover to work without using EMIF. If I fail one of the boxes, IP rolls over to the second box. When I power that box back up, IP stops working. If I then do a shutdown on the channel (on the box that was initially powered off), IP again works. On the host, they have 2 defaultnet statements, 1 pointing to each CPA port. Any ideas/thoughts would be appreciated.

Re: IP Redundancy on 7200's with CPA's

You should be able to use one IP stack on the mainframe, configured to connect simultaneouslly to the two CPA cards with the appropriate DEVICE and LINK statements, but use the VIPA address option so that the end users are not tied to a particular CPA interface.

There is an example of this at the following URL

This has the advantage of using both CPA cards concurrently.
