PowerPath in a Cluster Environment

2.If you are using PowerPath Volume Manager, configure VCS to recognize the PowerPath Volume Manager VCS Agent as a resource type by editing the

/etc/VRTSvcs/conf/config/main.cf file on one host in the cluster. Refer to Configuring VCS to Recognize PowerPath Volume Manager Resources on page 2-11.

3.On each node in the cluster, define the resources (for example, PowerPath Volume Manager volume groups or VxVM volumes) that make up the service group. (You will configure the service group in step 4.)

4.On one host in the cluster (if you are using PowerPath Volume Manager in the cluster, this should be the host where you edited main.cf in step 2; otherwise, this can be any host):

a.Configure the service group by adding the resources you defined in step 3 to the /etc/VRTSvcs/conf/config/main.cf file. The disk or logical device resources should use native c#t#d# devices.

Using a disk for service group heartbeat instead of a network is subject to restrictions. Not all disks can be used. Consult the VERITAS documentation.

b.Start cluster services on the host.

c.If you are using PowerPath Volume Manager, verify that VCS recognizes the PowerPath Volume Manager VCS Agent as a resource type. Enter:

hatype -list grep EMC

EMCvg should be listed in the command output.

5.Start cluster services on each remaining node in the cluster. These hosts rebuild their local configuration files from the main.cf file you edited in step 4.a.
