Issue/Introduction

On Deployment Wizard, while selecting an existing Scalability Server as a source of staged package, after a short loading the following message is shown: 

"Selected machine is not a Scalability Server"

The Scalability Servers works fine in any other way, this is the only place where an error or problem is seen.

Environment

Client Automation - All versions

Cause

Comparing DM Deploy logs while selecting the non working Scalability Server and a working SS, the following can be seen:

- Non working SS (server1):

|INFO   | CCFOSGeneral::GetNameFromAddress: 10.a.b.c resolved to: server1.domain
|DETAIL | isTargetDownV4 - sending echo request for <10.a.b.c>/ID 1

- Working SS (server2):

|INFO   | CCFOSGeneral::GetNameFromAddress: 10.a.b.c resolved to: server2.domain
|DETAIL | isTargetDownV4 - sending echo request for <10.a.b.c>/ID 1

|DETAIL | CAM queue DMPRIMER on host 10.a.b.c is running or startable



On the working Scalability Servers scenario, the Domain Manager is able to connect to its DM Primer, but on the non working Scalability Server, it's unable to. 

This is the cause of the error, in order to use Deployment Wizard, DM Primer has to be installed on the target Scalability Server.

Resolution

The first suggestion is to verify that DM Primer is actually installed on the non working Scalability Server, there are few ways to see this, first is to go to Apps section (under Control Panel) and check if it exists or not. If it exist, it may means that the version of DMPrimer is different than the DM, so would be good to uninstall it using this command:

MsiExec.exe /X {A312C331-2E7A-42E1-9F31-902920C402EE} /qn /norestart 

Then re-deploy the whole SS package to this server (from Deployment Wizard), but using the options "REINSTALL=ALL REINSTALLMODE=vomus" on 'Additional Windows Option', as a way to tell the installer to perform a full installation of the package, as explained here:

If this doesn't work, the SS can be re-register against the DM following these commands:

cserver unregister
caf setserveraddress localhost
cserver config -h <FQDN of Manager> -j
cserver register -a
