SPARC Enterprise T5120 and T5220 Servers Product Notes • October 2007

When running in a factory-default configuration, variable updates specified
through the Solaris OS eeprom(1M) command persist across a reboot of the
primary domain into the same factory-default configuration, but do not persist
into a configuration saved to the SP. Conversely, in this scenario, variable updates
specified using the Logical Domains Manager do not persist across reboots, but
are reflected in a configuration saved to the SP. When running the factory-default
configuration, if you want a variable update to persist across a reboot into the
same factory-default configuration, use the eeprom command. If you want it
saved as part of a new logical domains configuration saved to the SP, use the
appropriate Logical Domains Manager command.

All methods of updating a variable (OpenBoot firmware, eeprom command, ldm
subcommand) persist across reboots of that domain, but not across a power-cycle
of the system, unless a subsequent logical domain configuration is saved to the
SP. In addition, in the control domain, updates made using OpenBoot firmware
persist across a power-cycle of the system. That is, updates persist even without
subsequently saving a new logical domain configuration to the SP.

When reverting to the factory-default configuration from a configuration
generated by the Logical Domains Manager, all LDoms variables start with their
default values.

The ldm set-variable command enables you to set an LDoms variable to any
arbitrary string. However, many LDoms variables have only a small set of valid
values. For example boolean variables such as auto-boot? and diag-switch?
only accept the values true or false. If an LDom variable is set to a value that is
not valid, OpenBoot issues a warning message during boot with a list of correct
values, but without giving the name of the variable in question. For example:

The preceding message is given by OpenBoot if auto-boot? is set to a NULL
string. The boot stops at this point waiting for input. If you enters a space or a
carriage return the complete error message is displayed and the boot process
continues:
