Complete the following steps: You can also stop cluster services by using the  clmgr  command: clmgr stop node=hugo-atilio In our scenario, we have supported AIX levels for PowerHA V7.2.3 and do not need to  perform this step, but if you do this step, a restart is required before continuing. install_all_updates -vY -d .  1. Stop the cluster services on node hugo-atilio by running  smitty clstop  and selecting the  options that are shown in Figure 4-15 on page 106. The OK response appears quickly.  Make sure that the cluster node is in the  ST_INIT  state by reviewing the  lssrc -ls  clstrmgrES|grep state  output, as shown in Example 4-6. 2. Upgrade AIX. 3. Verify that the  clcomd  daemon is active, as shown in Figure 4-16. 4. Upgrade PowerHA on node hugo-atilio. To upgrade PowerHA, run  smitty update_all , as  shown in Figure 4-4 on page 95, or run the following command from within the directory in  which the updates are (Example 4-7): root@hugo-atilio:/> lssrc -s clcomd Subsystem Group PID Status  clcomd caa 6095310 active root@hugo-atilio:/>  Stop Cluster Services Type or select values in entry fields.
