Oracle Disk I/O Tuning Configuration of CFS or Raw Devices

Once hardware connection is made to the nodes in the Linux Cluster, install Data ONTAP 6.1.3 R2 give name (such as FDATA1) and IP Address for the filer storage unit.

Create a volume on the FDATA1 filer for storing Oracle Database files. This volume will be used to store all the data files, control files, and log files for the Oracle Database.

Use the at the filer console:

FDATA1> vol create oradata 14

Then Edit the /etc/exports file on FData1 and add the following entries to that file:

/vol/racdata -anon=0

Execute the following command at the filer console:

FData1> exportfs –a

Now create mount points and mount volumes.

Update the /etc/fstab file on all the server nodes and add the following entries:

FData1:/vol/racdata  -  /oradb nfs – Yes rw , bg , hard , nointr , rsize=32768,wsize=32768,tcp,noac,vers=3,timeo=600


FData1 is the name of the filer.
oradb is the mount point on the cluster nodes.
The mount options that are required for the Oracle RAC are:
   noac: This mount option disables caching on the client side.
   tcp:   Mount the file system using the tcp option.
