Cluster testing (IBM PowerHA)


NOTE: Stopping all clusters we would stop nfsserv last and start nfsserv first.

To stop cluster services:
      1. Enter the fastpath smit cl_admin or smitty hacmp.
      2. Select System Management (C-SPOC) and press Enter.
      3. Select Manage HACMP Services > Stop Cluster Services and press Enter
         Select an Action on resource groups
                 Bring resource groups Offline. HACMP stops all managed resources currently
                 ONLINE on the node being stopped. HACMP will not activate these resources on any
                other nodes, that is, no fallover.
          Stop now, on system restart or both
                NOW
        BROADCAST cluster shutdown?
                No



check the logs in.                                                                                                                                                                                                                            tail -f /var/hacmp/log/hacmp.out



To start cluster services:
       1. Enter the fastpath smit cl_admin or smitty hacmp.
       2. Select System Management (C-SPOC) and press Enter.
       3. Select Manage HACMP Services > Start Cluster Services and press Enter
           Select an Action on resource groups
              Start now, on system restart or both
               Start Cluster Services on these nodes
                           Enter the name(s) of one or more nodes on which you want to start clusterservices. Alternatively, you
                           you can select nodes from a picklist. Separate multiple nodes with a comma.
               Manage resource groups Automatically (default).
                    HACMP brings resource group(s) online according to the resource groups' configuration settings and the current                                                                                    cluster state and starts managing the resource group(s) and applications for availability.
           

check the logs in.         tail -f /var/hacmp/log/hacmp.out
Ensure cluster is stable      /usr/es/sbin/cluster/utilities/cldump


For status checking:


clshowsrv -v

clRGinfo -m
