10.13.1 Saving the OpenBoot PROM Environment Variables
This section describes the procedure for saving the OpenBoot PROM environment variables.
  1. Execute the printenv command to check the OpenBoot PROM environment variables.
  {0} ok printenv
  Variable Name           Value                          Default Value

  keyboard-layout
  reboot-command
  security-mode           none                           No default
  security-password                                      No default

  screen-#columns         80                             80
  screen-#rows            34                             34
  ttya-mode               9600,8,n,1,-                   9600,8,n,1,-
  output-device           virtual-console                virtual-console
  input-device            virtual-console                virtual-console
  auto-boot-on-error?     false                          false
  load-base               16384                          16384
  auto-boot?              false                          true
  os-root-device
  network-boot-arguments  host-ip=192.168.123.100, ...
  boot-command            boot                           boot
  boot-file
  boot-device             mydisk1 mydisk2 mydisk3  ...   disk net
  multipath-boot?         false                          false
  boot-device-index       0                              0
  use-nvramrc?            true                           false
  nvramrc                 devalias mydisk1 /pci@80 ...

  {0} ok
  1. Save the output result to a text file.
  1. If there is a variable with a value replaced with "..." in step 1, execute the printenv command with the corresponding variable specified.
  1. The following example checks the boot-device variable.
  {0} ok printenv boot-device
  boot-device =           mydisk1 mydisk2 mydisk3 mynet
  1. The following example checks the nvramrc settings.
  {0} ok printenv nvramrc
  nvramrc =               devalias mydisk1 /pci@8000/pci@4/pci@0/pci@0/scsi@0/disk@p3,0:a
                          devalias mydisk2 /pci@8100/pci@4/pci@0/pci@0/scsi@0/disk@p0,0:a
                          devalias mydisk3 /pci@8100/pci@4/pci@0/pci@0/scsi@0/disk@p1,0:a
                          devalias mynet /pci@8000/pci@4/pci@0/pci@9/network@0
                          h# 8 value video-mode
  1. The following example checks the network-boot-arguments settings.
  {0} ok printenv network-boot-arguments
  network-boot-arguments =  host-ip=192.168.123.100,subnet-mask=255.255.255.0,iscsi-target-ip=192.168.100.10,iscsi-target-name=iqn.2016-12.com.fujitsu:02:iscsiboot,iscsi-lun=0
  1. Save the output result in step 3 to a text file.
