Solution 2086110.1 : Format of cellip.ora for adding new storage cell X5 into existing Exadata

Applies to:

Exadata X3-2 Quarter Rack - Version All Versions to All Versions [Release All Releases]
Exadata X4-2 Quarter Rack - Version All Versions to All Versions [Release All Releases]
Exadata X5-2 Quarter Rack - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Goal

What is the configuration of file cellip.ora to add the Storage Cell X5-2 to the existing Exadata X2-2 or X3-2 or X4-2.

Suppose the existing Exadata is a quarter rack there would be only 3 lines in the cellip.ora file, one for each storage cells which pre-exists.

Example :

[oracle@db01:/etc/oracle/cell/network-config ] $ cat cellip.ora
cell="192.168.10.3"
cell="192.168.10.4"
cell="192.168.10.5"

Now with the addition of Storage Cell X5-2, should there be one line or 2 lines in the file cellip.ora of each DB Nodes?

cell="192.168.10.3"
cell="192.168.10.4"
cell="192.168.10.5"
cell="192.168.10.6" <<========== The new line of private network Storage Cell X5-2
cell="192.168.10.7" <<========== The new line of private network Storage Cell X5-2

cell="192.168.10.3"
cell="192.168.10.4"
cell="192.168.10.5"
cell="192.168.10.6;192.168.10.7" <<==========The new line of private network Storage Cell X5-2

What's the correct method to add the Storage cell X5-2 in the Exadata X3-2 ?

Solution

The second method is correct , because in x5-2 servers the InfiniBand interfaces are configured in active-active bonding.

you can have the below mixed format of cellip.ora

cell="192.168.10.3" ==> Format X3
cell="192.168.10.4" ==> Format X3
cell="192.168.10.5" ==> Format X3
cell="192.168.10.6;192.168.10.7" ==> Format X5

[oracle@db01:/etc/oracle/cell/network-config ] $ cat cellip.ora
cell="192.168.10.3"
cell="192.168.10.4"
cell="192.168.10.5"
cell="192.168.10.6;192.168.10.7"
