How do I check my Hacmp cluster status?
Monitoring cluster services on a node
- View Management Information Base (MIB)
- Look for cluster events and errors in the hacmp. out file.
- Use SMIT to check the status of the following PowerHA SystemMirror subsystems on a node: Cluster Manager ( clstrmgrES ) subsystem. SNMP ( snmpd ) daemon.
How do I check my PowerHA status?
You can see the complete topology configuration using the /usr/es/sbin/cluster/utilities/cltopinfo command. After checking cluster, node, and network interface status, check the status of the PowerHA SystemMirror and RSCT daemons on both nodes and clients.
How do you start Clcomd?
clcomd is started by inittab (entry created by PowerHA during install) and it is controlled by SRC: startsrc/stopsrc. Refresh is used to reread /etc/cluster/rhosts file and move the log files (/var/hacmp/clcomd/clcomd. log). The real use of the /etc/cluster/rhosts file is before the cluster is first synchronized.
How do I start a cluster in AIX?

What is cluster aware AIX?
Cluster Aware AIX (CAA) uses multicast communications for heartbeat and other protocol messages, which might require an additional network setup at customer site. The unicast cluster provides a new capability to CAA to support clustering with simultaneous unicasting of CAA protocol messages, instead of multicasting.
What is AIX cluster?
High availability clustering for AIX® The IBM® PowerHA® SystemMirror® software provides a low-cost commercial computing environment that ensures quick recovery of mission-critical applications from hardware and software failures. With PowerHA SystemMirror software, critical resources remain available.

What is Clcomd?
The information in clcomd. log provides information about all connections to and from the daemon, including information for the initial connections established during discovery. Because clcomddiag. log contains diagnostic information for the daemon, you usually do not use this file in troubleshooting situations.
How do you stop and start the Hacmp cluster in AIX?
Procedure for stopping cluster services
- Select PowerHA® SystemMirror® Services > Stop Cluster Services and press Enter.
- Table 1. Stop Cluster Services fields. Field. Value.
- Press Enter. The system stops the cluster services on the nodes specified. If the stop operation fails, check the /var/hacmp/log/cspoc.
What is CAA in Hacmp?
CAA (Cluster Aware AIX) It helps to easily create a cluster. CAA is not used as a stand-alone package, it is used with PowerHA or with Shared Storage Pool. It can be seen as a set of commands and services that other applications (like PowerHA, SSP) can exploit to provide high availability and disaster recovery support.
How do I replace a Hacmp repository disk?
From the SMIT interface, select Problem Determination Tools > Replace the Primary Repository Disk, and press Enter. In the Repository Disk field, press F4 (List) to select an available disk from all nodes in the cluster, or enter the name of the disk if a backup repository disk has not been configured.

What is CAA in AIX?
CAA is essentially a set of tools and services embedded into AIX that help to manage a cluster of AIX nodes and assist in running cluster software on AIX. Cluster products, such as PowerHA and RSCT from IBM, can utilise CAA to simplify the configuration, management and monitoring of an AIX cluster.
