Configuring cluster

After successfully installing InfoScale operator, you can create a cluster.

  1. Edit clusterInfo section of the sample /YAML/Kubernetes/cr.yaml for InfoScale specifications as under -

    Note:

    You can specify up to 16 worker nodes in cr.yaml. Although cluster configuration is allowed even with one Network Interface Card, Veritas recommends a minimum of two physical links for performance and High Availability (HA). Number of links for each network link must be same on all nodes. Optionally, you can enter node level IP addresses. If IP addresses are not provided, IP addresses of Kubernetes cluster nodes are used. 

     
spec:
 clusterID: <Optional- Enter an ID for this cluster>
 clusterInfo:
  - nodeName: <Name of the first node>
    ip:
    -  <Optional - First IP address of the first node >
    -  <Optional - Second IP address of the first node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                               to exclude from Infoscale disk group.>
  - nodeName: <Name of the second node>
    ip:
   -  <Optional - First IP address of the second node >
   -  <Optional - Second IP address of the second node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                               to exclude from Infoscale disk group.>
  - nodeName: <Name of the third node>
    ip:           
   -  <Optional - First IP address of the third node >
   -  <Optional - Second IP address of the third node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                                to exclude from Infoscale disk group.>                                               
 .
 .
 .
  YOU CAN ADD UP TO 16 NODES.

 
 
  customImageRegistry:  customImageRegistry: <Custom registry name /
                     <IP address of the custom registry>:<port number> >

    Note:

    Do not enclose parameter values in angle brackets (<>). For example, Primarynode is the name of the first node; for nodeName : <Name of the first node> , enter nodeName : Primarynode. InfoScale on Kubernetes is a keyless deployment.

  2. Run the following command on the master node.

    kubectl create -f /YAML/Kubernetes/cr.yaml

  3. Run the following command on the master node to know the name and namespace of the cluster.

    kubectl get infoscalecluster

    Use the namespace from the output similar to the following -

    NAME                   NAMESPACE        VERSION      STATE          AGE
infoscalecluster-dev   infoscale-vtas   8.0.100   Running   1m15s

  4. Run the following command on the master node to verify whether the pods are created successfully.

    kubectl get pods -n infoscale-vtas

    An output similar to the following indicates a successful creation of nodes

    NAME                             READY STATUS  RESTARTS AGE

After a successful InfoScale deployment, a disk group is automatically created. You can now create Persistent Volumes/ Persistent Volume Claims (PV / PVC) by using the corresponding Storage class.
