Description Ronnie Rasouli 2016-12-08 14:02:59 UTC

Description of problem:

We can scale down by using scale this provider option. 

By doing that there are missing validations of: node in maintenance mode, node has associated instances 

Version-Release number of selected component (if applicable):
5.7.0.14

How reproducible:
100%

Steps to Reproduce:
1. login to CFME UI
2. go to scale this provider 
3. decrease the number of compute nodes from 2 to 1 

Actual results:

scale down is done without validation of maintenance mode and associated instances 

Expected results:
block scaling down with scale this provider action

    bz 1402867: Prevent scale down in scaling UI
    
    https://bugzilla.redhat.com/show_bug.cgi?id=1402867
    
    In the scaling UI, added checks to allow scaling up but not down.
    Scale down is handled explicitly via a separate UI action with
    validation around maintenance mode on the node and lack of active
    VMs.
