Stopping services

For stopping services:

  • Stop Application servers
  • Stop Database servers
  • Stop NFS server


Stop Application servers

To stop application servers use:

  1. Put the cluster in maintenance mode: 
    crm configure property maintenance-mode=true
  2. Stop SAP services (PAS & AAS services) with help of SAP Application team
  3. Stop cluster services on Secondary node
      1. Stop pacemaker cluster
      systemctl stop pacemaker.service
    2. Check services status 
      crm status
  4. Stop cluster services on Primary node
    1. Stop pacemaker cluster 
      systemctl stop pacemaker.service
    2. Check cluster services status 
      crm status


Stop Database servers

To stop database server use:

  1. Put the cluster in maintenance mode: 
    crm configure property maintenance-mode=true
  2. Stop SAP DB services with help of SAP team
  3. Stop cluster services on Secondary node
    1. stop pacemaker cluster 
      systemctl stop pacemaker.service
    2. Check cluster services status 
      crm status
    3. Check HANA DB services status 
      su - <username>
      

      HDB info
  4. Stop cluster services on Primary node
    1. Stop pacemaker cluster 
      systemctl stop pacemaker.service
    2. Check cluster services status 
      crm status
    3. Check HANA DB services status 
      su - <username>
      

      HDB info


Starting services

To start services:

  • Start NFS servers
  • Start database servers
  • Start application servers


Start database servers

To start database server use:

  1. Start HANA DB manually on primary node. Take Help from SAP team
  2. Start cluster services on Primary node
    1. Start pacemaker cluster 
      systemctl start pacemaker.service
    2. Remove cluster from maintenance mode: 
      crm configure property maintenance-mode=false
    3. Check cluster services status 
      crm status
  3. After starting the services in master node, wait for 5-10 minutes
  4. Start cluster services on Secondary node
    1. Start pacemaker cluster 
      systemctl start pacemaker.service
    2. Check cluster services status 
      crm status


Start application servers

To start application servers use:

  1. Start cluster services on Primary node
    1. Start pacemaker cluster 
      systemctl start pacemaker.service
    2. Remove cluster from maintenance mode: 
      crm configure property maintenance-mode=false
    3. Check cluster services status 
      crm status
    4. Start SAP services (PAS & AAS services) with help of SAP Application team
  2. Check the cluster services on Secondary node
    1. Slave node might automatically restart due to fencing, after the pacemaker cluster is started on the Primary node
    2. Check cluster services status 
      crm status
