Dell HPC NFS Storage Solution High Availability Configurations with Large Capacities

1. Generate cluster configuration file.

On the „active‟ R710, manually modify the cluster configuration script according to the cluster

spec.

In /root/config_cluster.sh

Modify:

machine_active="active" #check section A.1.1

machine_passive="passive" #check section A.1.1

pdu1_ip="15.15.10.101" #check section A.1.1

pdu2_ip="15.15.10.102" #check section A.1.1

pdu_active_port="2" #check section A.1.1

pdu_passive_port="3" #check section A.1.1

drac_active_ip="15.15.10.201" #check section A.1.1

drac_passive_ip="15.15.10.202" #check section A.1.1

cluster_name="NSS61" #define the name of your cluster

num_HA=1 #define the number of HA services

set_IB=0 #if IB is used, set to 1.

HA_ip_1=10.10.10.200 #check section A.1.1

Then, execute the script

# /root/config_cluster.sh

Very important: once the cluster configuration file is generated, please double check the

configuration file to make sure all information is correct according to the specification in

section A.1.1. The generated configuration file is /etc/cluster/cluster.conf.

2. On both servers, start and check that the cman service is running:

# service cman start

# service cman status

3. On both servers, check the cluster status:

# clustat

Cluster status should show both servers online. If the cluster is up and running, then go on to the

next step.

[root@active ~]# clustat
