NIC change-Oracle RAC Cluster reconfiguration

Hi, This may be from database related but i would like to raise here to find excat solution ,
I am using Oracle 10.2.0.3 on HP-Unix 11.23,running on CFS cluster wiht 2 nodes configured, we are using UTP for NIC and we are going to upgrade to FC and i belive the no changes on IP, VIP,or port. Now Do i need to reconfigure teh oracle cluster again? if yes can any one provide the steps or Doc to do this task.

If you are not going to change any IP address or port then I don't think you need to reconfigure your cluster.

Shalom Chitta,

I see no need to reconfigure.

I would:
1) Notify the user community prior to starting.
2) Make sure all databases/packages are running on the node not being worked on to avoid accidental service interuption.

Re: NIC change-Oracle RAC Cluster reconfiguration

Oracle has explicit instruction on how to do this documented.

Notably in the "Oracle® Clusterware Administration and Deployment Guide"
For 11g that is:
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/votocr.htm#insertedID3

"To change the Network Interface Card (NIC) for the interconnect:

If you want to change the network interface for the private interconnect (for example, eth1), you must perform the change on all nodes (globally). This is because Oracle currently does not support the use of different network interface cards in the same subnet for the cluster interconnect. .... "

Re: NIC change-Oracle RAC Cluster reconfiguration

Hi,
I have seen the Cluster edit option on System mannagement homepage under hp service gaurd Manager, If i edit the value of interface name (i.e lan0 to lan4) will it take effect in Oracle Cluster, or do need to follow the Document again,
