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.
