Here are some very useful commands for the Hardware Management Console (HMC): Show vital product data, such as the serial number:
# lshmc -v
Show the release of the HMC:
# lshmc -V
Show network information of the HMC:
# lshmc -n
Reboot the HMC:
# hmcshutdown -r -t now
Show the connected managed systems:
# lssysconn -r all
Change the password of user hscpe:
# chhmcusr -u hscpe -t passwd -v abc1234
List the users of the HMC:
# lshmcusr
These are intersting log files of the HMC:
# ls -al /var/hsc/log/hmclogger.log
# ls -al /var/hsc/log/cimserver.log
Monitor the disk space:
# monhmc -r disk
This can be used to view the file systems of the HMC. Try using “proc”, “mem” and “swap as well. By default this command will loop forever and update the screen every 4 seconds. You can run it only once, with the following command:
# monhmc -r disk -n 0
Zero out log files:
# chhmcfs -o f -d 0
This will delete any temporary files. Extremely useful if the HMC calls home to IBM about high usage of one of its file systems. Open a virtual console from the HMC:
# vtmenu
Exit by typing “~.” (tilde dot) or “~~.” (tilde tilde dot). Force the closure of a virtual terminal session:
# rmvterm -m SYSTEM-9117-570-SN10XXXXX -p name
Change the state of a partition:
# chsysstate -m SYSTEM-9131-52A-SN10XXXXX -r lpar -o on -n name
-f default_profile
# chsysstate -m SYSTEM-9131-52A-SN10XXXXX -r lpar -o shutdown
-n name –immed
To start all partitions of one managed server:
# chsysstate -m Prd2-Server-8233-E8B-SN0XXXXXX -r lpar -o on –all
List partition profiles for a managed system:
# lssyscfg -r prof -m SYSTEM-9117-570-SN10XXXXX
List partition information:
# lspartition
