NetBackup installation on Red Hat Pacemaker Passive Node on Linux
This topic describes how to install and configure a new NetBackup Primary server as a failover application on a Red Hat Pacemaker on Linux.
Note:
You must install the NetBackup primary server on each node to which NetBackup may failover. You cannot have a separate failover primary server in the NetBackup configuration.
The following procedure describes how to install and configure a NetBackup failover server in a PCS cluster.
Note:
NetBackup automatically detects supported clustering technology and prompts questions based on it. If there are no prompts for questions on a clustered setup, do exit from the script and verify that the cluster is configured correctly.
To install a NetBackup failover server
- Follow the instructions from NetBackup Installation Guide, to install NetBackup. Be sure that you: Install NetBackup on each node to which it can fail over. Use the virtual name for the NetBackup server name.
Warning:
When you are prompted, you must provide the same virtual cluster name that you provided during the installation. This name must be in the same format (FQDN/short) on all the nodes.
- When NetBackup is installed on the clustered setup a confirmation prompt is displayed. When you install NetBackup on the first node, you are prompted to confirm creation of a NetBackup cluster.
Type Yes to set up NetBackup in HA mode. When you install NetBackup on the subsequent nodes, information about already created NetBackup cluster group is displayed. You are prompted to join the group.
- When you are prompted for cluster-specific configuration details, refer to the checklist and provide details accordingly.
- Allow NetBackup to be installed in a cluster. When a NetBackup failover server is installed: On the first node, a single node cluster resource group for NetBackup is created and brought online. On the other nodes, the installed node is added to the cluster resource group.
- Post installation, get the security certificates on all the nodes within the cluster. For more information, to get a certificate in a clustered NetBackup setup, refer to the NetBackup Security and Encryption Guide.
When PCS maker resource enters in blocked state, run the following commands to refresh the pacemaker:
pcs resource refresh
Once all resources are up and running, run the commandpcs resource cleanup
In case of RHEL Pacemaker cluster, the Host mappings do not get automatically discovered. Then, you must provide the details on how to generate the host mappings.
For example, RHEL Pacemaker cluster is configured with nodes such as Node1, Node2, and virtual name. Follow the steps to add manually the virtual name as a shared mapping between Node1 and Node2:
To add host mappings manually
- On the left, select Security > Host mappings.
- Select the host and click Manage mappings.
- Click Add.
- Enter the host name or IP address and click Save.
- Click Close.
Note:
If NetBackup automatically discovers any shared or cluster names associated with the NetBackup hosts in your environment, and which are not auto approved then follow the steps:
To approve the host mappings that NetBackup discovers
- On the left, select Security > Host mappings.
- Click the Mappings to approve tab.
- Click the name of the host.
- Review the mappings for the host and click Approve if you want to use the discovered mapping.
Click Reject if you do not want to associate the mapping with the host.
The rejected mappings do not appear in the list until NetBackup discovers them again.
- Click Save.
