When attempting to add an additional instance of AE to a server with existing AE instances, the following message is received:
The specified instance is already defined in the CA Workload Automation AE configuration. Specify another instance
Workload Automation AE (AutoSys)
When you run the installer and add an additional AE instance, you are prompted for an instance name.
The installer crosschecks the /etc/ directory for the existence of any auto.<instance> files that may bear the same instance name.
If it does find any, you will get the message "The specified instance is already defined in the CA Workload Automation AE configuration. Specify another instance".
Check if you do actually already have an instance with that name. Places to check to see if you already have an instance of that name:
'unisrvcntr status' command
Search for any autouser.<instance> directories with that instance name
Check /etc/init.d/waae* startup scripts bearing the instance name
Check your /etc/auto.profile file for references to that instance
If you are certain there is no active instance by that name and you suspect the existing /etc/auto.<instance> file is there by mistake (a remnant of a previously uninstalled instance, accidentally copied file, etc):
You may delete the /etc/auto.<instance> file. This will allow you to proceed with adding a new instance using that instance name.
