AIX PowerHA (HACMP) Commands


Most commands should work on all PowerHA (HACMP prior to 5.5) versions.
If there is some syntax error, please consult the manual page for that command.

Sometimes path to cluster commands not included in default PATH variable ,to overcome it run below command before running ha commands

export PATH=$PATH:/usr/es/sbin/cluster:/usr/es/sbin/cluster/utilities:/usr/es/sbin/cluster/sbin:/usr/es/sbin/cluster/cspoc
