The ILOM reset command generates a graceful or forced hardware reset of the server. By default, the reset command gracefully resets the server.

• Type one of the following commands to reset the server.
  • Perform a graceful reset from ILOM:

    -> reset /SYS

  • If a graceful reset is not possible, perform a forced hardware reset from ILOM:

    -> reset -force /SYS
