Step 2 - Connect to drs_engine1 through the management console (Engine1)
1.From the integrated console, use the PRT Scr key to access the IBM eServer p5 520 server drs_engine1. Hit Enter to see the login prompt.
Login dr550 Password xxxxxx
2.Once successfully logged on as dr550, issue the AIX command su - root to switch to root. Now you have the necessary AIX system rights to change the network settings and to reconfigure
HACMP.
Step 3 - Stop HACMP (if necessary)
1.Check if HACMP is running or stopped with the AIX command lssrc
2.If it is running, stop HACMP on each node. It is assumed there is no data traffic when stopping, since this is the implementation phase. It can take several minutes to stop HACMP. After HACMP is stopped, go on with the next step.
The following steps describe the procedure for stopping cluster services on a single node or on both nodes in the cluster by executing the
Important: When stopping cluster services, minimize activity on the system. If the node you are stopping is currently providing highly available services, notify users of your intentions if their applications will be unavailable. Let them know when services will be restored.
1.Log in to any of the IBM eServer p5 520 servers; use dr550 and switch to root. You can switch to root with the AIX command su - root.
2.On the AIX command line start SMIT by issuing the command smitty clstop
3.Use the default settings and change nothing when you want to stop only one of the nodes (the one you are logged in) with a graceful shutdown mode.
Tip: Because the DR550 is running a two node HACMP cluster, to stop only one of the both nodes is not a usual task. To stop only one node is needed for maintenance tasks only. Hence the normal stopping procedure for HACMP in the DR550 always includes the stopping of both nodes.
