To list status of all systems and LPARs connected to an HMC:
lslpars
lslpars --wide
To reboot the HMC:
hmcshutdown -t now -r
To issue a soft reset to an LPAR:
chsysstate -m <managedsystemname> -r lpar -n <lparname> -o reset
To issue a soft reset to a system running in FullSystemPartition mode:
chsysstate -n <managedsystemname> -r sys -o reset
To issue a hard reset to an LPAR:
chsysstate -m <managedsystemname> -r lpar -n <lparname> -o off
To issue a hard reset to a system running in FullSystemPartition mode:
chsysstate -n <managedsystemname> -r sys -o off
To open a console connection to an LPAR:
mkvterm -m <managedsystemname> -p <lparname>
To open a console connection to a system running in FullSystemPartition mode:
mkvterm -m <managedsystemname>
If the mkvterm command results in this error message:
"All available virtual terminal sessions have been opened and are in use. To force a new open session, perform a Close Terminal Session operation which frees up the session."
then either someone else already has a console open, or a console was improperly closed. You may choose to check with your colleagues before killing the console session using this command:
rmvterm -m <managedsystemname> -p <lparname>
To close a console connection: The session can be ended by typing ~ and . as the first characters on a line.
To view state and operator panel (LED/LCD display) of an LPAR:
lssyscfg -r lpar -m <managedsystemname> -n <lparname>
To view state and operator panel (LED/LCD display) of a system running in FullSystemPartition mode (note the -n):
lssyscfg -r sys -n <managedsystemname>
