Hi
Can someone share his experience in using multiple NIC for Private network and
therby focing Oracle to use multiple HAIP vs interconnect bonding. I had RAC
setup where OS level Private network Bonding is not failing over due to one
issue on NIC and causing Oracle cluster to bounce the node. This happen several
time and so checking Oracle Docs that says that 11g(11.2) onwards it is
recommended to use multiple nic and details from DOc is
"With Redundant Interconnect Usage, you can identify multiple interfaces to use
for the cluster private network, without the need of using bonding or other
technologies. This functionality is available starting with Oracle Database 11g
Release 2 (11.2.0.2). If you use the Oracle Clusterware Redundant Interconnect
feature, then you must use IPv4 addresses for the interfaces.When you define
multiple interfaces, Oracle Clusterware creates from one to four highly
available IP (HAIP) addresses. Oracle RAC and Oracle Automatic Storage
Management (Oracle ASM) instances use these interface addresses to ensure
highly available, load-balanced interface communication between nodes. The
installer enables Redundant Interconnect Usage to provide a high availability
private network.By default, Oracle Grid Infrastructure software uses all of the
HAIP addresses for private network communication, providing load-balancing
across the set of interfaces you identify for the private network. If a private
interconnect interface fails or become non-communicative, then Oracle
Clusterware transparently moves the corresponding HAIP address to one of the
remaining functional interfaces."
So want to check is someone is using and share the experience
