Solution
When failover occurs, follow these guidelines when conguring old versus new master nodes.
n
Before promoting another node to master, remove the previous master node from the load balancer
pool of vRealize Automation appliance nodes.
n
To have vRealize Automation bring an old master node back to the cluster, let the old machine come
online. Then, open the new master management console. Look for the old node listed as invalid under
the Database tab, and click its Reset buon.
After a successful reset, you may restore the old node to the load balancer pool of vRealize Automation
appliance nodes.
n
To manually bring an old master node back to the cluster, bring the machine online, and join it to the
cluster as if it were a new node. While joining, specify the newly promoted node as the primary node.
After successfully joining, you may restore the old node to the load balancer pool of vRealize
Automation appliance nodes.
n
Until you correctly reset or rejoin an old master node to the cluster, do not use its management console
for cluster management operations, even if the node came back online.
n
After you correctly reset or rejoin, you may promote an old node back to master.
Troubleshooting IaaS Components
The troubleshooting topics for vRealize Automation IaaS components provide solutions to potential
installation-related problems that you might encounter when using vRealize Automation.
Validating Server Certificates for IaaS
You can use the vcac-Cong.exe command to verify that an IaaS server accepts vRealize Automation
appliance and SSO appliance certicates.
Problem
You see authorization errors when using IaaS features.
Cause
Authorization errors can occur when IaaS does not recognize security certicates from other components.
Solution
1 Open a command prompt as an administrator and navigate to the Cafe directory at <vra-
installation-dir>\Server\Model Manager Data\Cafe, typically C:\Program Files
(x86)\VMware\vCAC\Server\Model Manager Data\Cafe.
2 Type a command of the form
Vcac-Config.exe CheckServerCertificates -d [vra-database] -s [vRA SQL server] -v. Optional
parameters are -su [SQL user name] and -sp [password].
If the command succeeds you see the following message:
Certificates validated successfully.
Command succeeded."
If the command fails, you see a detailed error message.
N This command is available only on the node for the Model Manager Data component.
