MC/Service Guard vs Secure Fast

[Jonas Petersson]

Hello!

We run a MC/Service Guard cluster based on 2 A500 HP-UX servers. This cluster is placed in a Secure Fast Network, the main application is an Informix 7.31 database.
Some of the clients who connects to this cluster is places in the Secure Fast Network and some areplaced outside it. The problem is, all of our clients are loosing connection to the database quite frekvently. My question is, is there any known problem running this kind of a cluster on a Secure Fast nerwork? Or is there anything we should pay extra attention to in this situation?

Best regards
Niclas

Generally I do not believe that your disconnects have anything specific to do with MC/ServiceGuard. The cluster only adds the relocatable IP adress during package start. This IP address is in principal the same as an alias IP address... which you would also get using ifconfig lanX:Y manually.

Running Informix as SG package is a quite usual solution. So I think network trouble-shooting needs to be started.

It looks more like a network issue than SG issue . All SG does is aasgin a virtual or movable IP to a package that get bind to an assigned NIC card on top of its static IP . Kind of an alias .

Try connecting your clients to the static IP first . IF they work fine , then the issue might be SG configuration . But if they have the same problem then it definitely is a network issue .
