Unable to ONLINE a service group after disbling the application resource

[paragarw]

I disabled my application resources(rs-app-db-004   and rs-app-rm-004)  for some testing purpose in a service group and saved the changes in the main.cf file.

Now this application resource is on top of the tree and no other resource depends on this. I made the service group offline and then disabled the resources using below command. Then when i tried  to bring the service group ONLINE, it threw the error "VCS NOTICE V-16-1-50036 There are no enabled resources in the group SG-APP-DS_RM-004 to online"

hares -modify rs-app-db-004 Enabled 0

hares -modify rs-app-rm-004 Enabled 0

hares -display -group SG-APP-DS_RM-004 | grep 'Enabled.*global'
rs-app-db-004           Enabled               global     0
rs-app-rm-004           Enabled               global     0
rs-dg-dsappdg-004       Enabled               global     1
rs-ip-dsarmvp-cls-004   Enabled               global     1

#hagrp -online SG-APP-DS_RM-004 -sys node1
VCS NOTICE V-16-1-50036 There are no enabled resources in the group SG-APP-DS_RM-004 to online
 

I am using version 5.1

Now i need inputs on below points.

1) Is it necessary that atleast one application resource should be Enabled in a service group?

2) Other resources like IP,mount are enabled then why is it throwing an error "There are no enabled resources"

3) is it a bug or am i missing any point.

Looking forward for your feedback.

Hi paragarw,

You hit one of the oddities of VCS.  The service group as a whole cannot be brought online if there is a single top most resource and that top most resource is disabled.  You either need to online all of the resources independantly or add another resource at the top level that is not disabled.

For some reason, VCS checks the top most resource to see if it is enabled.  If it is not then the group is not brought online even though there are enabled resources below the top most resource.

Thank you,

Wally
