VIP change interfaces eth->bond Oracle
605926Oct 30 2007 — edited Nov 5 2007Hi,
my current configuration is
RAC 10.2.0.3 (2 node cluster) on top of RHEL 4.4
I started RAC installation with eth0 for public and eth1 for private.
Latter on we decidet to go with bonds.
Now we have eth0 and eth2 ---> bond0 (public) and eth1 and eth3 ----> bond1 (interconnect).
So before I do this on my production system I need to succesfully simulated on my test RAC which was install with bond's preconfigured. That's why we doubled the bonds.. so that we can simulate the change from current interface to the new one.
---> the new one
[oracle@rac2 bonding]$ oifcfg iflist
bond2 10.10.8.0
bond3 192.168.1.0
----> the old one in the configuration
[oracle@rac2 bonding]$ oifcfg getif
bond0 10.10.8.0 global public
bond1 192.168.1.0 global cluster_interconnect
What would be the right procedure to change public and cluster_interconnect from bond0 to bond2 and from bond1 to bond3.
Is it enough if I shutdown nodeapps, listeners, instances, etc. and then use
srvctl modify nodeapps or I need to use oifctl defif first and then setif??
Or do I need to do both?
What would be the exact commands?
Many thanks in advance.
