HMC basic commands
Steps:
lssyscfg -r sys -F name:type_model:serial_num
Show managed lpars attached to a frame
lssyscfg -m <frame> -r lpar -F name
Show profiles from a specific lpar
lssyscfg -r prof -m <frame> --filter "lpar_names=<lpar>"
Shutdown lpar from HMC
chsysstate -m <frame> -r lpar -n <lpar> -o shutdown –immed
To perform a partition shutdown using the shutdown command on the client operating system
chsysstate -r lpar -o osshutdown –n <lpar> -m <frame>
To perform a delayed partition shut down (white button shut down):
chsysstate -r lpar -o shutdown –n <lpar> -m <frame>
To perform an immediate partition shutdown (operator panel function :
chsysstate -r lpar -o shutdown --immed –n <lpar> -m <frame>
To perform an immediate restart of a partition (operator panel function 3):
chsysstate -r lpar -o shutdown --immed --restart –n <lpar> -m <frame>
To perform a restart of a partition after initiating a dump (operator panel function 22):
chsysstate -r lpar -o dumprestart –n <lpar> -m <frame>
Boot lpar
chsysstate -r lpar -m <frame> -o on -n <lpar> -f <profile>
To perform a partition boot into system management services:
chsysstate -r lpar -m <frame> -o on -n <lpar> -b sms
To perform a partition boot into diagnostic with default bootlist
chsysstate -r lpar -m <frame> -o on -n <lpar> -b dd
To perform a partition boot into diagnostic with stored bootlist
chsysstate -r lpar -m <frame> -o on -n <lpar> -b ds
To perform a partition boot into diagnostic with stored bootlist
chsysstate -r lpar -m <frame> -o on -n <lpar> -b ds
To perform a partition boot into open firmware OK prompt
chsysstate -r lpar -m <frame> -o on -n <lpar> -b of
To perform a partition boot into normal mode
chsysstate -r lpar -m <frame> -o on -n <lpar> -b norm
Show free processor/memory/adapters on specific frame/lpar
Proc
lshwres -r proc -m <framename> --level sys
lshwres -r proc -m <framename> --level lpar
Mem
lshwres -r mem -m <framename> --level sys
lshwres -r mem -m <framename> --level lpar
Adapters
lshwres -r hca -m <framename> --level sys
lshwres -r hca -m <framename> --level lpar
Show io resources in a frame
lshwres -r io --rsubtype unit -m <frame>
lshwres -r io --rsubtype bus -m <frame>
lshwres -r io --rsubtype slot -m <frame>
What to do if you cannot execute CHMOD?
If you just ran 'chmod -x /bin/chmod'. What to do? How to recover it?
If you have just removed execute permission on chmod (/bin/chmod).
So that now you cannot modify file permissions. Not even for chmod itself .
chmod remains useless on your system.
Here is the solution for the problem.
Run the below commands whichever works in your server.
sudo /lib/ld-linux.so.2 /bin/chmod 755 /bin/chmod
or
perl -e 'chmod(0755, "/bin/chmod")'
