Ed, Yes, we have done that. The Metalink notes I remember using are 283684.1 & 276434.1 (possibly others) and things worked as documented. I think the Sysadmin has some additional notes on this process but it all worked well. Thanks.

I found a paper on metalink, that recommends using the oifcfg utility to do this. Basically, shut down the cluster and change the ip's using this utility. Has anyone done this, and are there any other issues I should consider. Thanks for your help. ed solaris 5.10, oracle 10.2.0.4
