SMASH (Systems Management Architecture for Server Hardware) is a set of standards and protocols used for managing server hardware. It is designed to provide a common management interface for servers, regardless of their make or model. This allows IT administrators to manage servers from different vendors using the same tools and procedures.

One of the protocols supported by SMASH is the Command Line Protocol (referred to as SMASH-CLP).

Common tasks[edit | edit source]

Reboot a server[edit | edit source]

On the SMASH-CLP shell, go to the root of the interface with cd / and navigate to the system (it's either /system or /system1). From there, you should see 'reset' as one of the verbs which you can run to reset the system. 

-> cd /
-> [TAB]
cd
exit
help
show
version
system

-> cd /system
COMMAND COMPLETED : cd /system
 ufip=/system

->show
COMMAND COMPLETED :
show
 ufip=/system1
  Targets:
...
      tempsensor47/
      tempsensor48/

  Properties:
      CurrentPowerStatus=ON
      SysIdSupported=SUPPORTED
      SysIdentification=OFF
      TimeOutValue=INVALID
      identity=host

  Verbs:
      cd
      exit
      help
      reset
      set
      show
      version

-> reset
 ufip=/system
COMMAND COMPLETED : reset

      Reset: Target reset successful

Shutdown / Start a server[edit | edit source]

On systems that support this feature, you should see 'start' and 'stop' as an available verb under the /system or /system1 target. 

-> show
COMMAND COMPLETED :
show

 ufip=/system1
  Targets:

      cpu1/
...
      tempsensor48/

  Properties:
      CurrentPowerStatus=ON
      SysIdSupported=SUPPORTED
      SysIdentification=OFF
      TimeOutValue=INVALID
      identity=host


  Verbs:
      cd
      exit
      help
      reset
      set
      show
      start
      stop
      version

-> start
COMMAND COMPLETED :
start

 ufip=/system1
      Start: Target started successfully

Connect to serial console[edit | edit source]

On systems that support this feature, you should be able to navigate to the /system1/sol1 target and run 'start' to connect to the serial console.

Hit the ^. escape characters to exit.

You must enable serial over lan for this feature to work. If it isn't enabled, you will get the following error message: 

->cd /system1/sol1
COMMAND COMPLETED :
cd /system1/sol1

 ufip=/system1/sol1

->start
COMMAND COMPLETED :
start

 ufip=/system1/sol1

 Enter ^. to exit from SOL
setting the MUX for SOL
SOL not enabled for BMC LAN channel 1.
SMASH SOL Stopped. Resetting the MUX.

You can enable SOL using ipmitool. For instructions, see my page about enabling SOL.

Troubleshooting[edit | edit source]

Low CPU clock speeds[edit | edit source]

A server was running at reduced clock speeds (1.2GHz when it should be at 3.4GHz). Resetting the power management target seemed to fix the issue. 

->cd /system1/pwrmanagement1
COMMAND COMPLETED :
cd /system1/pwrmanagement1

 ufip=/system1/pwrmanagement1

->reset
COMMAND COMPLETED :
reset

 ufip=/system1/pwrmanagement1
      Reset: Target reset successful
