Mit dem Kommando nimquery können Informationen zu allen Managed Systems einer HMC angezeigt werden:

Für alle an die HMC angebundenen Managed Systems werden eine große Menge an Informationen ausgegeben, unter anderem die für das Anlegen eines cec NIM-Objekts benötigten Informationen name, type_model und serial_num. Eine etwas übersichtlichere Ausgabe lässt sich durch Verwenden der Option „-p“ (print format) erreichen:

# nimquery -a hmc=hmc01 -p
CEC ms1 - 9105-22A_89B3572 :
        "lpar_proc_compat_modes = default
        "supported_vtpm_versions = 1.2
        2.0" = "supported_vtpm_encryptions
        2.0/Power10v1 = 2.0/Power10v2"
        5250_application_capable = 1
        POWER8 = POWER9
        POWER9_base = POWER10"
        active_lpar_mobility_capable = 1
…
        name = ms1
…
        serial_num = 89B3572
…
        type_model = 9105-22A
…
CEC ms2 - 9105-22A_89B3592 :
        "lpar_proc_compat_modes = default
        "supported_vtpm_versions = 1.2
        2.0" = "supported_vtpm_encryptions
        2.0/Power10v1 = 2.0/Power10v2"
        5250_application_capable = 1
        POWER8 = POWER9
        POWER9_base = POWER10"
        active_lpar_mobility_capable = 1
…
        name = ms2
…
        serial_num = 89B3592
…
       type_model = 9105-22A

Das Kommando nimquery erlaubt es außerdem automatisch cec NIM-Objekte für alle an einer HMC angebundenen Managed Systems anzulegen. Dazu muss lediglich die Option „-d“ (define) verwendet werden:

# nimquery -a hmc=hmc01 -d
/usr/sbin/nim -o define -t cec -a hw_serial=89B3572 -a hw_type=9105 -a hw_model=22A -a mgmt_source=hmc01 -a comments="object defined using nimquery -d"  9105-22A_89B3572
/usr/sbin/nim -o define -t cec -a hw_serial=89B3592 -a hw_type=9105 -a hw_model=22A -a mgmt_source=hmc01 -a comments="object defined using nimquery -d"  9105-22A_89B3592
...
# 

Als Name für die neuen cec NIM-Objekte wird eine Kombination aus hw_type, hw_model und hw_serial verwendet: <hw_type>-<hw_model>_<hw_serial>.

Wir lassen uns die angelegten cec NIM-Objekte einmal alle anzeigen:

# lsnim -t cec
ms21                 management       cec
9105-22A_89B3572     management       cec
9105-22A_89B3592     management       cec
...
# 

Das erste cec NIM-Objekt ms21 hatten wir manuell angelegt und als Namen für das Objekt den Namen des Managed Systems verwendet. Alle anderen Objekte wurden automatisch durch nimquery angelegt.

Alle cec NIM-Objekte besitzen über das Attribut mgmt_source einen Verweis auf das verwaltende hmc NIM-Objekt. Umgekehrt besitzt aber auch das hmc NIM-Objekt Verweise auf die verwalteten cec NIM-Objekte:

# lsnim -l hmc01
hmc01:
   class       = management
   type        = hmc
   passwd_file = /etc/ibm/sysmgt/dsm/config/hmc01
   manages     = 9105-22A_89B3572
   manages     = 9105-22A_89B3592
   comments    = DC1
   login       = nimadm
   manages     = ms21
   mgmt_port   = 12443
   if1         = net_192_168_199_0 hmc01 0
   Cstate      = ready for a NIM operation
   prev_state  = not running
   Mstate      = not running
