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
ttya-rts-dtr-off false false
ttya-ignore-cd true true
keyboard-layout
reboot-command
security-mode none No default
security-password No default
security-#badlogins 1 No default
diag-switch? false false
local-mac-address? false true
fcode-debug? false false
scsi-initiator-id 7 7
oem-logo No default
oem-logo? false false
oem-banner No default
oem-banner? false false
ansi-terminal? true true
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 ...
error-reset-recovery boot boot
{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.
