ECS: How to disable the Transformsvc transformation service

Verify that Transformsvc is enabled.  If 'Transformsvc enabled' displays as 'False', no further action is required.  In this example, it is set to 'True'

Confirm if the transformation is running an ongoing migration before disabling:

From the above, the CAS migration is complete.  If tasks are still pending, wait until all tasks success before disabling

Log into GUI with 'root' user.  Then press keys:

Ctrl + Alt + Shift + M

A new menu entry appears:

Manage -> Migration

There, you can disable Transformsvc as follows:

If unable to disable transformsvc from GUI, run the following commands.  This will set the 'Transformsvc enabled' to 'False'.  Note: this requires the GUI root user password

Command: 

#svc_rest_cmd -u root -p <p/w> POST -xml -d '<service_control_param><action>stop</action></service_control_param>' -H "Content-Type: application/xml" /object/transformation/status

#svc_node info all | egrep 'Node at rack|Transformsvc enabled'

Example:

admin@Node1:~> svc_rest_cmd -u root -p ChangeMe POST -xml -d '<service_control_param><action>stop</action></service_control_param>' -H "Content-Type: application/xml" /object/transformation/status
