How to enable/disable HA when the option is not available in vRealize Operations Manager UI

Products

• VMware Aria Suite

Issue/Introduction

This article provides steps to enable and disable HA when the option to do enable/disable is not available through the Admin UI.

 

Note: This option might not be available because the option is grayed out or the Admin UI is inaccessible.

Environment

VMware vRealize Operations 8.3.x
VMware vRealize Operations 8.4.x
VMware vRealize Operations 8.10.x
VMware vRealize Operations 8.2.x
VMware vRealize Operations 8.5.x
VMware vRealize Operations 8.6.x
VMware vRealize Operations 8.x

Resolution

Disabling HA

Use the CASA API to disable HA by running this command as root from any of the nodes in the cluster:

curl -i -k -u 'admin:password' -X POST https://master_node_IP/casa/config/cluster/ha -d '{"is_enabled":false}' -H "Accept: application/json" -H "Content-type: application/json"

Where:

• password is the password of the admin account.
• master_node_IP is the IP addresses of the Master node.

 

If the issue persists, use this alternate procedure:

1. Log into all nodes as root via SSH or Console.
2. Run this command on all nodes to stop the vRealize Operations Manager services and restart the cluster services:

service vmware-vcops-watchdog stop; service vmware-vcops stop; service vmware-casa restart

3. Run this command on the Replica and Data nodes:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --action=configureRoles --admin=false --data=true --ui=true --adminCS=master_node_IP --startServices false

Note: You should see an output similar to:
Exiting with exit code: 0, Successfully completed vC Ops configureRoles

4. Run this command on the Master and Remote Collector nodes:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --adminCS=master_node_IP --startServices false

Note: You should see an output similar to:
Exiting with exit code: 0, Successfully completed vC Ops configureRoles

5. Open the /usr/lib/vmware-vcops/user/conf/gemfire.properties file on all nodes and set shardRedundancyLevel=0.
6. Open the /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/data/roleState.properties on all nodes and set these values:

adminroleconnectionstring = master_node_IP
internaladminroleconnectionstring = master_node_IP

7. Run the following command on all nodes:

service vmware-vcops-watchdog start; service vmware-casa restart; service vmware-vcops start

 

 

Enabling HA

Use the CASA API to enable HA by running this command as root from any of the nodes in the cluster:

curl -i -k -u 'admin:password' -X POST https://master_node_IP/casa/config/cluster/ha -d '{"is_enabled":true, "replica_slice":"replica_node_IP"}' -H "Accept: application/json" -H "Content-type: application/json"

Where:

• password is the password of the admin account.
• master_node_IP and replica_node_IP are the IP addresses of the Master node and Replica node respectively.

 

If the issue persists, use this alternate procedure:

1. Log into  all nodes as root via SSH or Console.
2. Run this command on all nodes to stop the vRealize Operations Manager services and restart the cluster services:

service vmware-vcops-watchdog stop; service vmware-vcops stop; service vmware-casa restart

3. Run this command on the Replica node:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --action=configureRoles --admin=true --data=true --ui=true --adminCS=master_node_IP,replica_node_IP --startServices false

Note: You should see an output similar to:
Exiting with exit code: 0, Successfully completed vC Ops configureRoles

4. Run this command on the Master, Data, and Remote Collector nodes:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --adminCS=master_node_IP,replica_node_IP --startServices false

Note: You should see an output similar to:
Exiting with exit code: 0, Successfully completed vC Ops configureRoles

5. Open the /usr/lib/vmware-vcops/user/conf/gemfire.properties file on all nodes and set shardRedundancyLevel=1.
6. Open the /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/data/roleState.properties on all nodes and set these values:

adminroleconnectionstring = master_node_IP,replica_node_IP
internaladminroleconnectionstring = master_node_IP,replica_node_IP

7. Run the following command on all nodes:

service vmware-vcops-watchdog start; service vmware-casa restart; service vmware-vcops start
