Always backup eeprom.image files to tape or to a system other than the SSP.  
You may also want to keep extra copies on the SSP's disk.

BACKUP the following directories:

  $SSPVAR/.ssp_private/eeprom_save/        (this is the template directory)
  $SSPVAR/etc/platform_name/domain_name/   (these are the working copy
                                            directories, one for each domain.)

Where
- "platform_name" is the name of the 10000 platform.

- "domain_name" is the hostname of the 10000 domain.  If you have multiple 
  domains, you will have multiple directories (one for each domain) to backup.

To create an eeprom.image file:

1. Obtain hostid or serial number and key.

	- If you are recreating an eeprom.image file, these can be found in 
	the materials which shipped with the system.
	
	- If you are creating an eeprom.image for a new domain or have lost 
	your original documentation, contact SunService[SM] to get a new 
	host_id/serial_no and key.
	
	- Each domain will have a unique serial number or hostid and key.
	For the first domain, you use the serial number and the key; for
	any additional domains, you use the hostid and the key.

2. cd to the eeprom template directory:
	$SSPVAR/.ssp_private/eeprom_save
	
3. Use sys_id to create the new eeprom.image file:

   sys_id -f eeprom.image.domain_name -k key {- s serial_no | -h host_id}

where 
- "domain_name" is the host name for the domain.

- "key" is a 20 character string obtained from Sun, case is significant.

- "serial_no" is the serial number for the Starfire[TM] machine, use the serial 
  number only for the first domain.  Valid serial numbers are hex numbers in 
  the range 0xA65000 to 0xA65FFF.  Use the 0x to specify hex in the sys_id 
  command line.

- "host_id" is the host id for the domain, use only for additional domains 
  after the first one.  Valid host ids are hex numbers in the range 0xA66000 
  to 0xA66FFF.  Use the 0x to specify hex in the sys_id command line.

4. If this is a new domain, use domain_create(1M) to create the domain:

   domain_create -d domain_name -b sys_boardlist -o OS_version    -p platform_name

Where
- "sys_boardlist" is a list of the boards that comprise the domain.

- "OS_version" is the version of OS the domain will be running.

Domain_create will copy the eeprom.image to the working copy directory.

5. If you are recreating the eeprom.image for an existing domain, copy the 
template file to the working copy directory:

   cp $SSPVAR/.ssp_private/eeprom_save/eeprom.image.domain_name    $SSPVAR/etc/platform_name/domain_name/eeprom.image 

See sys_id(1M), domain_create(1M), and SSP User's Guide (805-0076) for more 
info.
