Info

Access Through Multiple Controller Sessions Up to five ALOM system controller sessions can be active concurrently, one session through the serial management port and up to four sessions through the network management port. Users of each of these sessions can issue commands at the sc> prompt, but only one user session can have write-access the the system console at anytime. The other sessions accessing the system console will have read-only capability. For more information, see: ■ “Using the Serial Management Port” on page 39 ■ “Activating the Network Management Port” on page 40.) Any additional ALOM system controller sessions afford passive views of system console activity, until the active user of the system console logs out. However, the console -f command, if you enable it, allows users to seize access to the system console from one another. For more information, see the Sun Advanced Lights Out Manager (ALOM) Online Help. Ways of Reaching the sc> Prompt There are several ways to get to the sc> prompt. These are: ■ If the system console is directed to the serial management and network management ports, you can type the ALOM system controller escape sequence (#.). Note – #. (pound period) is the default setting for the escape sequence to enter ALOM. It is a configurable variable. ■ ■ You can log in directly to the ALOM system controller from a device connected to the serial management port. See “Using the Serial Management Port” on page 39. You can log in directly to the ALOM system controller using a connection through the network management port. See “Activating the Network Management Port” on page 40. 32 Sun Fire V445 Server Administration Guide • August 2006
About the ok Prompt A Sun Fire V445 server with the Solaris OS installed is capable of operating at different run levels. A synopsis of run levels follows. For a full description, see the Solaris system administration documentation. Most of the time, you operate a Sun Fire V445 server at run level 2 or run level 3, which are multiuser states with access to full system and network resources. Occasionally, you might operate the system at run level 1, which is a single-user administrative state. However, the lowest operational state is run level 0. At this state, it is safe to turn off power to the system. When a Sun Fire V445 server is at run level 0, the ok prompt appears. This prompt indicates that the OpenBoot firmware is in control of the system. There are a number of scenarios in which OpenBoot firmware control can happen. ■ By default, the system powers up to OpenBoot firmware control before the OS is installed. ■ The system boots to the ok prompt when the auto-boot? OpenBoot configuration variable is set to false. ■ ■ ■ ■ The system transitions to run level 0 in an orderly way when the OS is halted. The system reverts to OpenBoot firmware control when the OS crashes. When a serious hardware problem develops while the system is running, the OS transitions smoothly to run level 0. You deliberately place the server under firmware control in order to execute firmware-based commands or to run diagnostic tests. It is the last of these scenarios which most often concerns you as an administrator, since there will be times when you need to reach the ok prompt. The several ways to do this are outlined in “Entering the ok Prompt” on page 33. For detailed instructions, see “Entering the ok Prompt” on page 38. Entering the ok Prompt There are several ways to enter the ok prompt, depending on the state of the system and the means by which you are accessing the system console. In order of desirability, these are: ■ Graceful shutdown ■ ALOM system controller break or console command ■ L1-A (Stop-A) keys or Break key ■ Externally initiated reset (XIR) Chapter 2 Configuring the System Console 33
