You have a partitioned database grid on an X3-2 full rack with two four-node RAC clusters called
CLUSA and CLUSB. The storage grid, however, has not been partitioned.
Which files on which servers must be modified after connecting an Exadata storage full expansion
rack to your X3-2 Exadata Database Machine on the InfiniBand network so that the cells on the
expansion rack are added to the storage grid?

A.
The CELLINIT.ORA files on database servers in CLUSA

B.
The CELLIP.ORA files on the database servers in CLUSA

C.
The CELLINIT.ORA files on the database servers in CLUSB

D.
The CELLIP.ORA files on all existing and newly added Exadata storage servers.

E.
The CELLIP.ORA files on the database servers in CLUSB

Explanation:
Note:
*cellinit.ora, cellip.ora
— on database server
cellinit.ora – identifies the storage network interface on the database server
cat /etc/oracle/cell/network-config/cellinit.ora
cellip.ora – identifies the Exadata cells that are accessible to the database server
cat /etc/oracle/cell/network-config/cellip.ora
*The cellip.ora is the configuration file, on every compute node, that tells ASM instances which

cells are available to this cluster.
Here is a content of a typical cellip.ora file for a quarter rack system:
$ cat /etc/oracle/cell/network-config/cellip.ora
cell=”192.168.10.3″
cell=”192.168.10.4″
cell=”192.168.10.5″
