Shutting down the system with Netezza Performance Server

Learn how to power off IBM® Cloud Pak for Data System with Netezza Performance Server running on it.

1. Log in to the control plane node and verify the state of the system:

   [root@e1n1 ~]# ap state -d
   System state is 'Ready'
   Application state is 'Ready'
   Platform management state is 'Active'

2. Run ap node and make a note of nodes on system.

   ap node

3. Shut down Netezza Performance Server by running the following commands:
   1. docker exec -it ipshost1 bash
   2. su - nz
   3. rm /nz/.gpfstoken
   4. nzstop
   5. exit to come out of nz.
   6. exit to come out of docker.
4. Stop the system and services running the commands from e1n1:

   [root@e1n1 ~]# ap apps disable VDB --force

   [root@e1n1 ~]# ap apps

   Wait and verify that VDB gets to the DISABLED state:

   [root@e1n1 ~]# apstop
   System in 'Stopped' state

   [root@e1n1 ~]# apstop --service
   Successfully deactivated system
   Stopping Magneto service on all nodes

   Note: Ignore the message: Problem occurred: Some service stopping steps failed on nodes fbond.
5. Shut down GPFS file system from first control node. From e1n1 run:

   [root@e1n1 ~]#systemctl stop nfs
   [root@e1n1 ~]#mmumount all -a
   [root@e1n1 ~]#mmshutdown -a

6. Verify GPFS file systems are unmounted:

   [root@e1n1 ~]# mmlsmount all -L

   Example output:

   [root@e1n1 ~]# mmlsmount all -Lmmcommon: mmremote command cannot be executed. Either none of the
   nodes in the cluster are reachable, or GPFS is down on all of the
   nodes. mmlsmount: Command failed. Examine previous error messages to
   determine cause.

7. Shut down docker on all the control nodes:

   [root@e1n1 ~]# for node in $(/opt/ibm/appliance/platform/xcat/scripts/xcat/display_nodes.py --control); do ssh $node "service docker stop";done

   Example:

   [root@e1n1 ~]# for node in $(/opt/ibm/appliance/platform/xcat/scripts/xcat/display_nodes.py --control); do ssh $node "service docker stop";done
   Redirecting to /bin/systemctl stop docker.service
   Redirecting to /bin/systemctl stop docker.service
   Redirecting to /bin/systemctl stop docker.service

8. Shut down nodes from e1n1, in the following order:
   1. Power off all SPU (NPS) nodes (enclosures 3 and 4 in the example)
   2. Shut down the ICPD nodes (enclosures 1 and 2 in the example)
   3. Power off the ICPD nodes

   [root@e1n1 ~]# for ip in e{3..4}n{1..4}bmc; do ipmitool -I lanplus -H $ip -U USERID -P PASSW0RD power off; done

   [root@e1n1 ~]# ssh e2n4 'shutdown -h'
   [root@e1n1 ~]# ssh e2n3 'shutdown -h'
   [root@e1n1 ~]# ssh e2n2 'shutdown -h'
   [root@e1n1 ~]# ssh e2n1 'shutdown -h'
   [root@e1n1 ~]# ssh e1n4 'shutdown -h'
   [root@e1n1 ~]# ssh e1n3 'shutdown -h'
   [root@e1n1 ~]# ssh e1n2 'shutdown -h'
   [root@e1n1 ~]# shutdown -h

9. Verify that all nodes are powered off. Wait 5 - 10 minutes.

   Check that the power LEDs are blinking on all the nodes.

10. Physically remove power from the D2 enclosures, the fabric switch, and management switch.
