AIX: HMC Commands - Technical Blog For System Administrator

1) HMC Information

lshmc -v Shows vital product data, such as the serial number.

lshmc -V Shows the release of the HMC.

lshmc -n Shows network information of the HMC.

lssysconn -r all Show the connected managed systems

monhmc -r disk Look at the filesystems of the HMC. Try using “proc”, “mem” and “swap as well.

ls -al /var/hsc/log/hmclogger.log ls -al /var/hsc/log/cimserver.log Intersting log files of the HMC

vtmenu Open a virtual console from the HMC. Exit by typing “~.” (tilde dot) or “~~.” (tilde tilde dot).

hmcshutdown -t now -r Reboot the HMC

chhmcusr -u hscroot -t passwd change the HMC password (of user hscroot)

Add an SSH key for remote access for hscroot mkauthkeys -a “public key” Use the public key found in the users .ssh directory for public key (i.e. the contents of the file ~/.ssh/id_rsa.pub). mkauthkeys -u user -a “public key” 2) Managed system and LPAR related commands:

lssyscfg -r sys -F name | grep umfrm1 shows the full name of the managed system (what we can use in other commands) lssyscfg -r lpar -m -F name shows the full name of the lpars of the managed system lssyscfg -r sys -m -F name,state –header shows the state of the managed system lssyscfg -r lpar -m -F name,state –header shows the state of the lpars of the managed system lssyscfg -r prof -m aix10-SN0603C6H –filter “lpar_names=umfrm2” -F name,boot_mode it will show the boot mode in the profile lssyscfg -r prof -m -F lpar_name,virtual_eth_adapters shows LPARS with ethernet adaptesr and VLAN tags

lshwres -r mem -m –level sys shows memory information of the managed system lshwres -r mem -m –level lpar shows memory information of lpars of the managed system lshwres -r proc -m –level sys shows processor information of the managed system lshwres -r proc -m –level lpar shows processor information of lpars of the manage system lshwres -r io -m –rsubtype slot shows IO slot information lshwres -r proc -m –level sys -F installed_sys_proc_units:configurable_sys_proc_units

lshwres -r virtualio –rsubtype scsi -m –level lpar lists scsi devices by LPAR lshwres -r virtualio –rsubtype eth -m –level lpar lists virt. eth. devices by LPAR lshwres -r virtualio –rsubtype eth -m –level lpar -F lpar_name,port_vlan_id

chsysstate -m -o standby -r sys power on a system to standby chsysstate -r sys -m -o off normal power off the managed system chsysstate -r sys -m -o off –immed fast power off the managed system

chsysstate -m -r lpar -n -o shutdown –restart it will reboot an lpar with dump chsysstate -m -r lpar -n -o shutdown –immed –restart it will reboot an lpar immediately (without dump) chsysstate -m -r lpar -n -o shutdown –immed it will shutdown the oprating system chsysstate -m aix10-SN65158BE -o on -r lpar -n aix10 -f default it will activate an lpar

mksyscfg -r prof -m -o save -p -n –force it overwrites profile with actual running config

lspartition -dlpar shows dlpar capable partitions (it will show if RMC connection is OK between the HMC and LPAR)

lssysconn -r all to see what IPs are assigned by the HMC mksysconn -o auto tells HMC to re-discover all servers’ IP address

3. Console Information

lssvcevents -t console -d 60 lists console events in the past 60 days lssvcevents -t hardware -d 0 list serviceable events which occured today lssvcevents -t console -d 300 | grep DLPAR list DLPAR operations of last 300 days (you can grep more to mem or proc) lssvcevents -t console -d 7 | grep Migration list last 7 days LPMs

4.opening/closing virtual terminal from hmc:

lssyscfg -r sys -F name lssyscfg -r lpar -m -F name mkvterm -m -p rmvterm -m -p ~~.

5. Show Status and LED/LCD Display of an LPAR

lsrefcode -m pserver -r lpar –filter “lpar_names=mylpar” -F lpar_name:refcode

You can even see the history of LED codes. Just use -n for the last NUM codes. For example, if you want to see the last 5 LED codes of an LPAR type

hscroot@umhmc> lsrefcode -m pserver -r lpar –filter “lpar_names=mylpar” -n 5 -F lpar_name:refcode mylpar: mylpar:0c33 mylpar: mylpar:0539 mylpar:0538 … and for the status LEDs:

hscroot@umhmc> lsled -m pserver -r sa -t virtuallpar –filter “”lpar_names=mylpar””
