Configuring Workflow Automation in VCS

After you install Workflow Automation (WFA) in VCS, you must configure WFA in VCS using configuration scripts for high availability.

Before you begin

  • You must have installed the same version of WFA on both the cluster nodes.
  • You must have the same installation path for both the nodes.
  • You must create a backup of WFA.

Procedure

  1. Log in to the first node of the cluster.
  2. Use Cluster Manager to verify that the HA state of both nodes is running.
  3. At the shell prompt, run the ha_setup.pl script to move the WFA data to the shared location and to configure WFA with VCS for failover: perl ha_setup.pl --first [-t type_of_cluster_vcs] [-g cluster_group_name] [-e NIC_card_name] [-i IP_address] [-m Netmask] [-n cluster_name] [-f mount_point_of_shared_LUN] [-v name_of_logical_volume] [-d disk_group_name] [-l install_directory]
    For the default installation location, the script is available at /opt/netapp/wfa/bin/ha/.
    perl ha_setup.pl --first -t vcs -g WFA -e eth0 -i 10.238.170.3 -m 255.255.255.0 -n wfa_cluster -f /mnt/wfa_mount/ -v lun_volume -d lun_dg -l /opt/netapp/wfa
  4. Use Cluster Manager to verify that the WFA services, mount point, virtual IP, NIC, and volume group are added to the cluster group.
  5. Use Cluster Manager to move the WFA resources to the secondary node:
    1. Select and right-click the cluster group.
    2. Select Switch To > Secondary Node.
  6. Verify that the data mount, virtual IP, volume group, and NIC cards are up on the second node of the cluster.
  7. Take the WFA services offline by using Cluster Manager:
    1. Select WFA > Application > wfa-server.
    2. Right-click and select Offline.
    3. Select WFA > Application > wfa-db.
    4. Right-click and select Offline.
  8. At the shell prompt, run the ha_setup.pl script on the secondary node of the cluster to configure WFA to use the data from the shared location: perl ha_setup.pl --join [-t type_of_cluster_vcs] [-f mount_point_of_shared_LUN]
    For the default installation location, the script is available at /opt/netapp/wfa/bin/ha/.
    perl ha_setup.pl --join -t vcs -f /mnt/wfa_mount/
  9. Go to Cluster Manager and click Cluster Group > Online > Server.
    It might take a while before Cluster Manager shows that the application resources are online. You can also right-click the application resources and verify whether the resources are online.
  10. Ensure that WFA is accessible through the IP address used during this configuration.
