Included in PowerHA 7.1 Service Pack 3 and also with the upcoming PowerHA 6.1 and 5.5 Service Packs, a new command called 'halevel' is being introduced.

The 'halevel' command, just like the AIX oslevel command, shows the PowerHA version/release/modification and optionally the Service Pack (SP) installed.
