Sample Configurations with SGeRAC and Oracle RAC 10gR2, March 2009

Create disk groups for RAC

Use the vxdg command to create disk groups. Use the –s option to specify shared mode, as in the

following example:

# vxdg –s init cfsdg1 c4t1d0

Create disk group multi-node package

Add the disk group to the cluster.

# cfsdgadm add cfsdg1 all=sw

Package name "SG-CFS-DG-1" was generated to control the resource

Shared disk group "cfsdg1" was associated to the cluster

Activate disk group

# cfsdgadm activate cfsdg1

Creating volumes and adding a Cluster File System

# vxassist -g cfsdg1 make vol1 7000m

# vxassist -g cfsdg1 make vol2 7000m

# vxassist -g cfsdg1 make vol3 300m

# newfs -F vxfs /dev/vx/rdsk/cfsdg1/vol1

version 7 layout

7168000 sectors, 7168000 blocks of size 1024, log size 16384 blocks

largefiles supported

# newfs -F vxfs /dev/vx/rdsk/cfsdg1/vol2

version 7 layout

7168000 sectors, 7168000 blocks of size 1024, log size 16384 blocks

largefiles supported

# newfs -F vxfs /dev/vx/rdsk/cfsdg1/vol3

version 7 layout

307200 sectors, 307200 blocks of size 1024, log size 1024 blocks

largefiles supported

Configure mount point

# cfsmntadm add cfsdg1 vol1 /cfs/mnt1 all=rw

Package name "SG-CFS-MP-1" was generated to control the resource

Mount point "/cfs/mnt1" was associated to the cluster

# cfsmntadm add cfsdg1 vol2 /cfs/mnt2 all=rw

Package name "SG-CFS-MP-2" was generated to control the resource

Mount point "/cfs/mnt2" was associated to the cluster

# cfsmntadm add cfsdg1 vol3 /cfs/mnt3 all=rw

Package name "SG-CFS-MP-3" was generated to control the resource

Mount point "/cfs/mnt3" was associated to the cluster

Mounting Cluster File System

# cfsmount /cfs/mnt1

# cfsmount /cfs/mnt2

# cfsmount /cfs/mnt3

Check CFS mount points

# bdf | grep cfs
