Installing from OperatorHub by using Command Line Interface (CLI)

After you download YAML_8.0.320.tar.gz from Veritas Download Center and unzip and untar it, a folder /YAML/OpenShift/OLM/ is created and all files required for installation are available in the folder. An OpenShift cluster already has a namespace openshift-operators. You can choose to install InfoScale DR Manager in openshift-operators.

Complete the following steps on the primary and the secondary clusters.

  1. Copy the following content to a file and save the file as infoscale-dr-sub.yaml.
    ---
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: infoscale-dr-manager-sub
  # Namespace should be either infoscale-vtas
  # or openshift-operators
  namespace: infoscale-vtas
spec:
  channel: stable
  name: infoscale-dr-manager
  installPlanApproval: Manual
  # Source can be infoscale-dr-manager-catalog
  # if infoscale-dr-catsrc.yaml is used
  source: certified-operators
  sourceNamespace: openshift-marketplace
  startingCSV: infoscale-dr-manager.v8.0.320
  2. Run the following command on the bastion node to create a namespace infoscale-vtas. Ignore if you want to install in openshift-operators.

    oc create namespace infoscale-vtas

    Review output similar to the following to verify whether the namespace is created successfully. 

    namespace/infoscale-vtas created
  3. Run the following command on the bastion node to create a subscription.

    Note:

    If you want to install InfoScale DR Manager in openshift-operators namespace, edit infoscale-dr-sub.yaml. Change namespace from infoscale-vtas to openshift-operators. To install the latest bundle, modify startingCSV to infoscale-dr-manager.v8.0.320.

    oc create -f infoscale-dr-sub.yaml

    The following output indicates a successful command run. 

    subscription.operators.coreos.com/infoscale-dr-manager-sub created
  4. Run the following command on the bastion node.

    oc get subscriptions -n infoscale-vtas

    The following output indicates a successful command run. 

    NAME                                PACKAGE 
infoscale-dr-manager                infoscale-dr-manager
infoscale-licensing-operator        infoscale-licensing-operator 
infoscale-operator                  infoscale-operator 
nfd-stable-redhat-operators
             openshift-marketplace  nfd     

    SOURCE                               CHANNEL
infoscale-dr-manager-catalog         stable
infoscale-lic-operator-test-catsrc   stable
infoscale-sds-operator-catalog       stable
redhat-operators                     stable
  5. Run the following command on the bastion node.

    Change infoscale-vtas to openshift-operators, if you are using that namespace.

    oc get installplans --namespace infoscale-vtas

    Use <installation-name> from the output similar to the following output:

    NAME                  CSV                             APPROVAL   APPROVED
<installation-name>   infoscale-dr-manager.v8.0.320   Manual     false
  6. Run the following command on the bastion node.

    oc patch installplan <installation-name> --namespace infoscale-vtas --type merge --patch '{"spec":{"approved":true}}'

    The following output indicates a successful command run.

    installplan.operators.coreos.com/<installation-name> patched
  7. Run the following command on the bastion node.

    oc get installplans --namespace infoscale-vtas

    Review output similar to the following. Check if APPROVED is true.

    NAME                CSV                    APPROVAL APPROVED
<installation-name> infoscale-dr-manager.  Manual   True
                                   v8.0.320
  8. Run the following command on the bastion node to check the status of csv.

    oc get csv

    Components which are being installed or are pending installation are listed. Run the command again till you see the phase for all components as 'Succeeded'

    NAME                                   DISPLAY

4.10.0-202206010607                                Succeeded
  9. After InfoScale-dr-manager CSV is in a 'Succeeded' phase, proceed with the custom resource configuration and creation.
  10. Follow the steps that are listed in Configuring Global Cluster Membership (GCM), Configuring Data Replication, Additional requirements for replication on Cloud, Configuring DNS, and Configuring Disaster Recovery Plan.
