Cause
The vRealize Automation appliance nodes do not correctly form a high availability cluster until they can
resolve the short hostnames of the nodes in the cluster.
Solution
To allow a cluster of high availability vRealize Automation appliances to resolve short hostnames, take any
of the following approaches. You must modify all appliances in the cluster.
Procedure
n
Edit or create a search line in /etc/resolv.conf. The line should contain domains that hold
vRealize Automation appliances. Separate multiple domains with spaces. For example:
search sales.mycompany.com support.mycompany.com
n
Edit or create domain lines in /etc/resolv.conf. Each line should contain a domain that holds
vRealize Automation appliances. For example:
domain support.mycompany.com
n
Add lines to the /etc/hosts le so that each vRealize Automation appliance short name is mapped
to its fully qualied domain name. For example:
node1 node1.support.mycompany.com
node2 node2.support.mycompany.com
Proxy Prevents VMware Identity Manager User Log In
Conguring to use a proxy might prevent VMware Identity Manager users from logging in.
Problem
You congure vRealize Automation to access the network through a proxy server, and VMware Identity
Manager users see the following error when they aempt to log in.
Error Unable to get metadata
Solution
Prerequisites
Congure vRealize Automation to access the network through a proxy server. See “Connect to the
Network Through a Proxy Server,” on page 132.
Procedure
1 Log in to the console of the vRealize Automation appliance as root.
2 Open the following le in a text editor.
/etc/sysconfig/proxy
3 Update the NO_PROXY line to ignore the proxy server for VMware Identity Manager logins.
NO_PROXY=vrealize-automation-hostname
For example: NO_PROXY="localhost, 127.0.0.1, automation.mycompany.com"
4 Save and close proxy.
5 Restart the Horizon workspace service by entering the following command.
service horizon-workspace restart
