Systems

ELOM (Embedded Lights Out Manager) is used on at least the following Sun systems:

• Sun Fire X2200 M2
• Sun Fire X2100 M2

Host Management

From Managing the Host:

• To power on the host, enter the following command:

set /SP/SystemInfo/CtrlInfo PowerCtrl=on

• To power off the host gracefully, enter the following command:

set /SP/SystemInfo/CtrlInfo PowerCtrl=gracefuloff

• To power off the host forcefully, enter the following command:

set /SP/SystemInfo/CtrlInfo PowerCtrl=forceoff

• To reset the host, enter the following command:

set /SP/SystemInfo/CtrlInfo PowerCtrl=reset

• To reboot and enter the BIOS automatically, enter the following command:

set /SP/SystemInfo/CtrlInfo BootCtrl=BIOSSetup 

• To start start a session on the server console, enter this command:

start /SP/AgentInfo/console 

User Management

Managing User Accounts

• You should immediately change the password of the ELOM root account from the default value of changeme when logging into the ELOM command-line interface (CLI).

/SP -> set /SP/User/root Password=password
Set 'Password' to password

• Adding a user account (CLI) with administrator access.

/SP -> create /SP/User/user
Enter new password: 
Enter new password again: 
creating user...
create successful

/SP -> /SP -> set /SP/User/user Permission=Administrator
Set 'Permission' to 'Administrator'

Network Boot

The first time you boot a system with ELOM, it will attempt a network boot because there is no OS on its hard disks. However, once an OS is installed, a network boot can be difficult from the ssh console.

I seem to be unable to send an F12 via the ssh console to boot the system from the network. As a workaround, press F3 during boot to bring up a menu of boot devices (i.e., BBS POPUP) and select a network boot device.

Also, I recommend setting Quick Boot to Disabled within Boot/Boot Settings Configuration to give you more time to press the function keys during bootup.
