Initializing the Veritas Volume Manager

Use the following steps to create a two node SGeRAC cluster with CFS and Oracle:

1. Initialize the Veritas Volume Manager

If not already done, install the VxVM license key on all nodes. Use the following command:

# vxinstall

(For each question raised when running the vxinstall command to install the VxVM

licence key, respond with “n”.)

NOTE: CVM 4.1 or later does not require rootdg

2. Create the Cluster ASCII file:

# cd /etc/cmcluster

# cmquerycl -C clm.asc -n ever3a -n ever3b

Edit Cluster file

3. Create the Cluster

# cmapplyconf -C clm.asc

4. Start the Cluster

# cmruncl

# cmviewcl

The following output will be displayed:

CLUSTER STATUS

ever3_cluster up

NODE STATUS STATE

ever3a up running

ever3b up running

5. Configure the Cluster Volume Manager (CVM)

Configure the system multi-node package, SG-CFS-pkg, to configure and start the CVM/CFS

stack. Unlike VxVM-CVM-pkg, the SG-CFS-pkg does not restrict heartbeat subnets to a

single subnet and supports multiple subnets.

# cfscluster config -s

The following output will be displayed:

CVM is now configured Starting CVM

When CVM starts up, it selects a master node, which is the node from which you must issue

the disk group configuration commands. To determine the master node, issue the following

command from each node in the cluster:

# vxdctl -c mode

The following output will be displayed:

mode: enabled: cluster active SLAVEmaster: ever3b

mode: enabled: cluster active MASTERmaster: ever3b
