How to set the diagwait parameter

Following is the action plan to set the diagwait parameter:

1)  Stop database and other services across all the nodes
    
     $srvctl stop database -d <db_name>
     $srvctl stop asm -n node1
     $srvctl stop asm -n node2
     $srvctl stop nodeapps -n node1
     $srvctl stop nodeapps -n node2
2)  Stop the cluster on all the nodes
    
     As root:
     #crsctl stop crs
     #<CRS_HOME>/bin/oprocd stop

3)  Ensure that Clusterware stack is down on all nodes by executing
    
     #ps -ef |egrep "crsd.bin|ocssd.bin|evmd.bin|oprocd"

4)  From one of the node set the diagwait
    
     As root:
     #crsctl set css diagwait 13 -force

5)  Check if diagwait is set successfully by executing, the following command.
    
     #crsctl get css diagwait

6)  Start cluster on all the nodes
    
     As root:
     #crsctl start crs

7)  Check the status of cluster
    
     crsctl check crs

8)  Validate the status of all the services
    
     crsstat.ksh
