ping 10.50.254.51 from where ? the same server it is configured on or from somewhere else entirely, e.g. a different server on a different subnet with no connectivity to 10.50.254.x ?

So you want to effectively split the system into two sections, so that any process that uses lan900 (and its child processes, if any) is prevented from using lan1, and vice versa?

That cannot be done with basic network settings. You would need an add-on product like Secure Resource Partitions (SRP) or its predecessor, HP-UX 11i Security Containment.

Unfortunately, SRP is available for 11.31 only, and the Security Containment is for 11.23 only.
