Step 2. Assign one or more primary IP addresses to the IPoIB PPAs.
$ ifconfig lan9000 192.168.1.1
$ ifconfig lan9002 192.168.2.1
$netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lan9002 2044 192.168.2.0 192.168.2.1 0 0 0 0 21
lan9000 2044 192.168.1.0 192.168.1.1 0 0 0 0 21
lan0 1500 15.61.184.0 15.61.185.200 358628 0 262540 0 0
lo0 4136 127.0.0.0 127.0.0.1 0 0 0 0 0
snap9000 1492 101.102.101.0 101.102.101.200 0 0 0 0 0
snap9001 1492 101.102.201.0 101.102.201.200 0 0 0 0 0

Step 3. Use itutil to assign an IP address to the virtualization group.
$itutil -V add ib_vg 192.168.1.1 ib_links all
========================================================================
Virtual group created successfully with IP address 192.168.1.1
========================================================================$
Once a virtualization group is assigned an IP address, further calls to assign another IP address to
the virtualization group will fail. To modify the IP address associated with the virtualization group,
the IP address configuration has to be deleted using itutil -V delete option and be reassigned with
the new address using itutil -V add option. It is strongly recommended to not run any applications
while configuring or deconfiguring virtualization group.
Step 4. List the interfaces under the virtualization group for confirmation.
$ itutil -V get ib_vg
========================================================================
Virtual group IP address : 192.168.1.1
IAs IPoIB PPAs
ib0 lan9000 lan9001
ib1 lan9002 lan9003
========================================================================$
Oracle Cluster Configuration
When Database/Oracle administrator wants to use the InfiniBand HCAs for cluster communication, he or she
will need to pick the correct IP address. The correct IP address is what was assigned to the virtualization
group configured using itutil. The database may fail to come up if a different IP address is chosen by the
database administrator. Selecting the IP address for cluster communication implicitly chooses the entire set
of HCAs in the virtualization group for Oracle-RAC communication.
For further details on general Oracle RAC administration, please refer to the related documents from Oracle.
