Building Disaster Recovery Serviceguard Solutions Using Continentalclusters for Linux B.01.00.00

Log in as root user.a.
b. Set the password for conclusr on the node.
# passwd conclusr
2. Set up SSH equivalence between the nodes in the Continentalclusters.
a. Log in to any node in the Continentalclusters as conclusr.
b. Create a text file and add the Fully Qualified Domain Names (FQDN) of all the nodes
in all the clusters to be configured in the Continentalclusters.
For example, consider a Continentalclusters with two clusters, Cluster A and Cluster B,
each having two nodes, Node 1 and Node 2. Create a text file <host-list-file>,
with the following entries:
Node1.cup.hp.com
Node2.cup.hp.com
Node1.ind.hp.com
Node2.ind.hp.com
c. Run the following Serviceguard for Linux command to create and distribute the SSH keys:
# cmsshsetup -f <host-list-file>
The SSH keys set up trust among all the Continentalclusters nodes. This command also
prompts for the password of the user conclusr, for every node specified in the file
created in step 2b. Enter the password when prompted.
After the keys are created and distributed, the SSH connection is tested. If errors are detected
in the SSH connection, an error message appears. Rectify the error on the node, and run the
following command:
# cmsshsetup -f <host-list-file>
NOTE: For more information on cmsshsetup command, see cmsshsetup(1) manpage.
3. The conclusr must have a USER_ROLE of MONITOR. All users on a node have this role by
default. To confirm if conclusr has MONITOR access, on every node that belongs to
Continentalclusters, log in as conclusr and run the following command:
# cmviewcl
In case conclusr user does not have MONITOR access, the execution of the command fails
with the following error:
# cmviewcl
Permission denied to 127.0.0.1
cmviewcl: Cannot view the cluster configuration:
Permission denied. This user doesn't have access to view the cluster configuration.
nl
To resolve this error, edit the cluster configuration file, by including the following information:
USER_NAME conclusr
USER_HOST ANY_SERVICEGUARD_NODE
USER_ROLE MONITOR
Apply the cluster configuration file. Now, you must be able to view the cluster configuration
using the cmviewcl command.
