First you need to check some information for your system on the HMC. Issue the command vtmenu to get the managed system ID and the names of the partitions
hscroot@localhost:~> vtmenu
Retrieving name of managed system(s) . . . 108F19C
———————————————————-
Partitions On Managed System: 108F19C
———————————————————-
1) MANUFACTURING Running:
2) RETAIL Running:Enter Number of Running Partition (q to quit): q
Bye.
On this example I tried to soft reset the partition called MANUFACTURING
hscroot@localhost:~> chsysstate -m 108F19C -r lpar -n MANUFACTURING -o reset
Since it didn’t work out as expected, I decided to power off the LPAR
hscroot@localhost:~> chsysstate -m 108F19C -r lpar -n MANUFACTURING -o off
hscroot@localhost:~> vtmenu

Partitions On Managed System: 108F19C
———————————————————-
1) MANUFACTURING Ready:
2) RETAIL Running:Enter Number of Running Partition (q to quit): q
Bye.
I turned the partition on and after that it worked flawlessly
hscroot@localhost:~> chsysstate -r lpar -m 108F19C -o on -n MANUFACTURING
hscroot@localhost:~> vtmenu
