This is an in-depth explanation for use with the AIX Basics Certification Guide. (Continued from here)

1. Shutdown and reboot the system → shutdown -h, shutdown -r
2. Start or stop logical partitions → HMC
3. Recognize system or partition hangs and crashes

To shutdown or reboot the lpar from the lpar itself:

shutdown -> Shuts down the lpar

shutdown -r -> Reboots the lpar

Start or stop logical partitions

This process is performed from the HMC (stopping an lpar is the same as shutdown).

Select Systems, Specified System, Check the LPAR -> Operations

**If you would like to start a new profile, or initiate changes made to a profile, you will need to shutdown and start up the lpar

When shutting down the LPAR it will ask you if you are replacing the battery.  Make sure you don’t select this as this will call home to IBM (unless you want to do that…)

Recognize system or partition hangs and crashes

There are many ways to monitor and check the status on your LPAR.  Make sure you use the “errpt” command to view the error report.  AIX has a system hang detection in place, more info here, which will write to a log file upon system hang.
