HMC commands
Reset connection to a host on the HMC
Clear the connection history if you want to remove and add again a managed system:
hmc@hscroot > mksysconn -o auto
list UAK (update access key) on Power 8 and later
You have a firmware expiration date, it me be renew in case of expired
hmc@hscroot > lslic -m 9119-MME*??????? -F mtms,update_access_key_exp_date 9119-MME*???????,04/01/2019
You can enable an automatic renewal, go to Service Management → Transmit Service Information and select Update Access Key Information with some interval.
Basic command for HMC
Open a terminal on a host using command line:
mkvterm -m managed-system {-p partition-name | --id partition-ID} [--help] Open a virtual terminal session for the partition with an ID of 1: mkvterm -m 9406-570*12345678 --id 1 Exit the Vterm using ~~. or ~.
To get the names of server(s) managed by an HMC:
hscroot@sfohmc1:~> lssyscfg -r sys -F name Server-9133-55A-SN062EEBH Server-9406-MMA-SN103A7C0 Server-8233-E8B-SN0623B7P
To list LPAR names and LPAR profile names:
hscroot@sfohmc1:~> lssyscfg -r prof -m Server-8233-E8B-SN0623B7P --header -F lpar_name,name lpar_name,name 06-23B7P,default_profile vio1,default vio2,default
- Add a virtual FC adapter on VIOs and the targeted LPAR (Commands from the HMC)
For the VIO (DLPAR vfc “server” on LABVIO01 into slot 34, for LPAR labaix01 slot 14)

Adding/removing VLAN TAG dynamically: (it will not add to profile)
adding:
chhwres -r virtualio --rsubtype eth -m <man.sys.> -o s -p <LPAR> -s <adapter id> -a "addl_vlan_ids+=<VLAN TAG>"
removing:
chhwres -r virtualio --rsubtype eth -m <man.sys.> -o s -p <LPAR> -s <adapter id> -a "addl_vlan_ids-=<VLAN TAG>"
Changing LPAR weight:

Changing simplified restart capability, to change it we currently need to change it during LPAR poweroff:
hscroot@hmc:~> lssyscfg -m p812-srv1 -r lpar --filter "lpar_names=lparlab" -F simplified_remote_restart_capable 0 hscroot@hmc:~> chsyscfg -m p812-srv1 -r lpar -i "name=lparlab,simplified_remote_restart_capable=1" An error occurred while changing the partition named lparlab. HSCLA9F8 The remote restart capability of the partition can only be changed when the partition is shutdown.
=⇒ LPAR propertie: Remote Restartable (Simplified): Activated
Now you are able to start the LPAR once poweroff directly on another server Restart LPAR only if poweroff
hscroot@hmc:~> rrstartlpar -o restart -m 'p812-srv1' -p lparlab -t p812-srv2
How to list the system connections. This way you can check what error you have if you are not able to see the partitions on a squadron.
hscroot@hmc$ lssysconn -r all
How to check if the lpars have connection with the current HMC. This is useful when you have issues related to DLPAR operations.
hscroot@hmc:~> lspartition -dlpar <#36> Partition:<7*9117-MMA*56A3R4A, , 192.168.207.63> Active:<1>, OS:<AIX, 6.1, 6100-06-05-1115>, DCaps:<0x2c5f>, CmdCaps:<0x1b, 0x1b>, PinnedMem:<1137>

What to do if you reconnect the management system to HMC and it is not recognized (to clear the HMC's connection history):
hscroot@hmc$ mksysconn -o auto
How to list 3 days of console events:
hscroot@hmc$ lssvcevents -t console -d 3
How to list 3 days of console events for a specific lpar:

How to free up partition resources with chhwres command in Power 7: You have a currently active partition with 0.6 processing units assigned to it and you want to stop it and not using it for a while.
Use the chhwres command to free up this resource from the partition:
hscroot@hmc:~> chhwres -r proc -m FRAME -o r --id 6 --procunits 0.6

Clone LPAR config from HMC/IVM
To generate a “mksyscfg” command line from a single LPAR, run the following command on the HMC (this should all be on 1 long line). Change the highlighted yellow parts with the name of the LPAR and the managed system name:
lpar=aix1; system=p520; printf "##Command to create $lpar ($system)\nmksyscfg -r lpar -m $system -i \""; lssyscfg -r prof -m $system --filter "lpar_names=$lpar,profile_names=`lssyscfg -r lpar -m $system --filter "lpar_names=$lpar" -F default_profile`" | sed -e 's/\(^\|,\)name=/profile_name=/' -e 's/,lpar_name=/,name=/' -e 's/"/\\"/g' -e 's/$/"/'; printf "#\n#\n"
lssyscfg -r prof -m P7C3 --filter lpar_names=$NAME -F lpar_env,virtual_fc_adapters | \ tr -s ',' '\n' | perl -lne 'print $1 if m%\w+vios\d+/(\d+)/%' | sort -n | head -1) ADAP2=$((ADAP1+1)) echo "Adapter: $ADAP1 $ADAP2" echo
