Answer to questions below:
-->in this scenario what would be the state of resource and service group.
The resource state would be in a "waiting to online" state
-->what they mean by suspended ? Is it s state of a resource group.
Suspended means it appears the resources and service groups are doing nothing (i.e suspended) as the resource just sits in the same state "waiting to online" state until resource times out (or you flush service group). Suspended it not a state.
--> when we configure any resource with wrong attibutes and tries to bring online
Yes - this is when it is normally used in in initial configuration where a resource has wrong attribute in VCS or the resource is configured wrong in the O/S and therefore you realise it is not going to online - if you don't flush, then you have to wait for the OnlineTimeOut period (by default 5 mins) before you can try online again and if you do wait the 5 mins and the resource is critical then the resource will fault and service group will fail to other system(s), so flushing group means you don't have to wait for resource to timeout and the resource will not fault.
You use probe to force a monitor of a resource - by default VCS monitors online resources every 60 seconds and offline resources every 5 mins - so probing resource does a one-off monitor. You can use this when testing killing a resource so you don't have to wait up to 60 seconds for VCS to take action or you can use this if you bring resource up outside of VCS control and you don't want to wait up to 5 mins for VCS to realise it is online.
