HMC - CLI

HMC command line:

The 2 mostly used commands to gather info about managed systems and lpars:

lssyscfg: info about managed system, lpar (i.e. running or not) or profile configuration
lshwres: info about the resources (cpu/mem/vscsi..) of a managed system or lpar

------------------------------------------------------------
------------------------------------------------------------

lssyscfg

Lists managed-systems, partitions, partition profiles and attibutes of them. When you give resource type you can choose from: sys, lpar or prof.

If sys or lpar has been chosen it does not list resources like cpu/mem settings or vscsi/vfc adapter config, only general info about the system/lpar, like lpar is activated or not, what is the cpu mode, or rmc state...

If prof is chosen, it lists cpu,mem,vscsi... config from the lpar profile. (lshwres command shows these data from the running partition, not from the profile.)


lssyscfg -m <sys> -r <res> --filter "<name>=<value>,<value>" -F <attr>,<attr> --header

-m name of the managed system (if omitted all managed systems will be listed)

-r resource type
     sys gives general indo about managed system
     lpar gives general info about lpar
     prof gives specific infos (cpu, mem, vscsi..) from the lpar profile

--filter select values for a specific resource only (lpar_ids, lpar_names and profile_names)
   "lpar_ids=...,..."
   "lpar_names=...,."
   "profile_names=.."

-F display only the given attributes (name of the attr. will not be displayed and delimeter can be specified)

--header show header of the displayed values

------------------------------------------------------------

lssyscfg -r sys -F name lists name of managed systems (this name can be used in other commands)

lssyscfg -m <sys> -r lpar lists general info of lpars on the managed sys.
lssyscfg -m <sys> -r prof lists all settings in the lpar profiles on the managed sys.

other example:
lssyscfg -m <sys> -r lpar -F name,state --header                                  lists lpars and if it is activated or not
lssyscfg -m <sys> -r prof -F lpar_name,virtual_eth_adapters                        lists lpars with eth. adapters (vlan tags will be shown as well)
lssyscfg -m <sys> -r prof --filter "lpar_names=<lpar>" -F name,virtual_fc_adapters lists vfc adapters (with wwpn) of an lpar


------------------------------------------------------------
------------------------------------------------------------

lshwres:

Lists hardware resources of the managed-system and lpars, including physical I/O, virtual I/O, cpu/mem settings, (shared) processor pool, etc.

lshwres -m <sys> -r <res> --rsubtype <subtype> --level <lpar/sys> --filter "<name>=<value>,<value>" -F <attr>,<attr> --header

-m name of the managed system (lssyscfg -r sys -F name)

-r resource type
     io      physical io
     mem memory
     proc    processing unit
     virtualio virtual io

--rsubtype subtype of the resource given previously (it works for io and virualio)
     io       slot, slotchildresn (these can be used for the resource 'io')
     virtualio eth, fc, scsi, vswitch (these can be used for the resource 'virtualio')

--level      display info of managed system or lpar (it works for mem, proc and virtualio)
     lpar info is taken from lpar level (i.e memory values of the lpars)
     sys info is taken from system level (i.e memory value of the managed system)

--filter select values for a specific resource only (not all value can be used as filter)
   "lpar_ids=...,..."
   "lpar_names=...,."
   "vlans=...,...,.."

-F display given attributes (the name of the attribute will not be displayed and delimeter can be specified)

--header show header of the displayed values

------------------------------------------------------------

lshwres -m <sys> -r io --rsubtype slot/slotchildren shows io slot information (or children devices of slots)


MEM/PROC (mem/proc):

lshwres -m <sys> -r virtualio --rsubtype fc --level lpar    shows virt. fc adapters with lpar_name,slot_id, wwpns...
lshwres -m <sys> -r virtualio --rsubtype scsi --level lpar shows vscsi adapters with lpar_name,slot_id...


SR-IOV (sriov):
lshwres -m <sys> -r sriov --rsubtype physport --level ethc lists physical port config: location, speed, mtu size ...
lshwres -m <sys> -r sriov --rsubtype logport --level eth   lists logical port config: capacity, mac address, vlans ...
chhwres -m <sys> -r sriov --rsubtype physport -o s -a “adapter_id=1,phys_port_id=1,conn_speed=10000”  change phys. port config

other example:
lshwres -m <sys> -r virtualio --rsubtype eth --level lpar --filter "lpar_names=<lpar>" -F slot_num:addl_vlan_ids  shows lpar virt. adapters and vlans

/usr/samples/tcpip/anon.ftp

If you want to use remote FTP installs on HMC, an FTP user will be needed on the remote (AIX) server.
There is a default script on AIX which creates an ftp or anonymous user for this FTP connection: /usr/samples/tcpip/anon.ftp
This scripts should be used to create FTP user, otherwise connection will work but files won’t be reachable by HMC.
