Managing cluster and resources - 10g RAC

Hi, 

As part of routine maintenance of clusterware resources, we issued ./crs_stop -all on node 1 and this off-lined all the resources on both the nodes and 

after that we shut down the cluster using crsctl stop crs

Questions:

1. When we started the cluster services back using crsctl start crs, it automatically started up and ONLINED all the resources on both nodes, and we 

did not have to use srvctl or crsctl commands to bring the resources online one by one. Is this the normal behaviour that crsctl start crs will 

automatically bring up all the resources automatically?

2. What does Oracle recommends to use to manage cluster resources, crsctl or srvctl?
