I have a running AIX partition and want to change the boot mode to SMS next time when the server reboots. (HMC command will be great to know)

I was able to do this, When I shutdown the partition and later activate the profile in SMS mode

Run the following as "hscroot" using the HMC CLI:

HMC command to change the boot mode at next reboot:

chsyscfg -r prof -m  managedsys -i "lpar_name=lparname,name=profilename,boot_mode=sms"

HMC command to boot an LPAR into SMS mode:

chsysstate -r lpar -m managedsys -n lparname -o on -b sms

So the first command, will set the boot mode to SMS if I reboot the server.

I guess the second command does the same thing, Does it automatically boot the LPAR..??

The second command does not change the default boot mode - it actually boots the LPAR once into SMS without changing its future behavior. I just mentioned it for completeness.

The first command is the one you should use to set the target mode of future reboots to SMS. Change it back to normal with "boot_mode=norm".
