Resetting an LPAR on a Power4 system
Posted by Emerson Takahashi on July 23, 2010
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
Retrieving name of managed system(s) . . . 108F19C
———————————————————-
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
Retrieving name of managed system(s) . . . 108F19C

Partitions On Managed System: 108F19C

1) MANUFACTURING Starting:
2) RETAIL Running:Enter Number of Running Partition (q to quit): q
Bye.
