Installation guide

each node or start the cluster software on each cluster node by running the following

commands at each node in this order:

1. service cman start

2. service clvmd start, if CLVM has been used to create clustered volumes

Note

Shared storage for use in Red Hat Cluster Suite requires that you be running the

cluster logical volume manager daemon (clvmd) or the High Availability Logical

Volume Management agents (HA-LVM). If you are not able to use either the

clvmd daemon or HA-LVM for operational reasons or because you do not have

the correct entitlements, you must not use single-instance LVM on the shared

disk as this may result in data corruption. If you have any concerns please

contact your Red Hat service representative.

3. service gfs start, if you are using Red Hat GFS

4. service rgmanager start

5. Start the Red Hat Cluster Suite management GUI. At the Cluster Configuration Tool tab,

verify that the configuration is correct. At the Cluster Status Tool tab verify that the nodes

and services are running as expected.
