Goal

This document will serve as a step-by-step guide in performing a complete software and hardware powering off and on Sun Fire[TM] 6800 and/or Sun Fire[TM] E6900 server(s) for scheduled maintenance such as datacenter powerdown and powerup events.

Solution

Instructions

Assumptions:
  • Solaris[TM] 8 2/02 Operating Environment or higher
  • Firmware ScApp 5.18.1 RTOS 41 or higher (as the SC commands and behavior were based on 5.18.X FW)
  • Dual domain configuration, domain A and C with fully populated boards (3 per domain).

Quick High-level Overview Of Steps


Power Down Procedure:


1.  Properly and gracefully shutdown the Solaris Operating Environment on the configured domains on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).

2.  Use the System Controller's (SC) "setkeyswitch off" command from the domain shell and "poweroff all" command from the platform shell to control and power off all of the hardware components on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).

3.  From a hardware perspective, for completely powering off your Sun Fire 6800 and/or Sun Fire E6900 Server(s) follow the "top-to-bottom" sequence, turning off the following switches - Frame Manager keyswitch towards the top-most portion of the system chassis first, then the 2 AC input box switches in the middle rear portion of the system chassis next, and lastly the 4 Redundant Transfer Switches (RTS) towards the bottom-most portion  of the system chassis (2 in the front and the other 2 in the back).
NOTE: Please note that the 2 Frame Manager fan tray switches at the top rear portion of the system chassis should not be powered on and off ? The switches should remain in the "on" position at all times (as these switches control the Frame Manager chassis and gets powered on or off by the Frame Manager main keyswitch at the top-most portion of the system chassis).
Power Up Procedure:

1.  From a hardware perspective, for completely powering on  your Sun Fire[TM] 6800 and/or Sun Fire[TM] E6900 Server(s) follow the "bottom-to-top" sequence, turning on the following  switches - The 4 Redundant Transfer Switches (RTS) towards  the bottom-most portion of the system chassis (2 in the front and the other 2 in the back) first. Allow 30 seconds to one minute for the RTS modules to completely power on.  Next, the 2 AC input box switches in the middle rear portion of the system chassis, and lastly the Frame Manager keyswitch towards the top-most portion of the system chassis.
NOTE: Please note that the 2 Frame Manager fan tray switches at the top rear portion of the system chassis should not be powered on and off ? The switches should remain in the "on" position at all times (as these switches control the Frame Manager chassis and gets powered on or off by the Frame Manager main keyswitch at the top-most portion of the system chassis).
2.  Use the System Controller's (SC) "poweron all" command from the platform shell and "setkeyswitch on" command from the domain shell to control and power on all of the hardware components on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).

3.  Boot the Solaris[TM] Operating Environment on the configured domains on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).

Detailed Step-By Step Procedure:


Power Down Procedure:

"Top-To-Bottom" Sequence:

1.  Properly and gracefully shutdown the Solaris Operating Environment on the configured domains on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).
# shutdown -y -g0 -i0
This should bring your domains to the OBP (Open boot PROM) level also known as the "ok prompt".
       
Perform this on all configured domains on your Sun Fire 6800 and/or Sun Fire E6900 Server(s).

2.  Access the system controller and connect to the system controller main menu. Please refer to "Establishing Connections to the SC" in the "Sun Fire  Midrange System Administration Guide".
You can either have serial connections (such as tip connections or serial terminal connections) or remote connections (such as ssh, telnet, rlogin).
# telnet schostname
Trying xxx.xxx.xxx.xxx
Connected to schostname.
Escape character is '^]'.
where "schostname" is the system controller host name.

3.  Connect to the platform shell.
System Controller `schostname':
Type 0 for Platform Shell
Type 1 for domain A
Type 2 for domain B
Type 3 for domain C
Type 4 for domain D
Input: 0
Connected to Platform Shell
schostname:SC>

4.  After shutting down the Solaris Operating Environment on the configured domains on your Sun Fire 6800 and/or Sun Fire E6900 Server(s) and connecting to the platform shell, connect to the 2 domain shells (again, our assumption here is that this is a dual domain A and C config, wherein we would connect to each domain one at a time), and perform a "setkeyswitch off" command to power off the components for the corresponding domains on your Sun Fire 6800 and Sun Fire E6900 Server(s).
schostname:SC> console a
Connected to Domain A
Domain Shell for Domain A
schostname:A> setkeyswitch off
schostname:A> disconnect
schostname:SC>
schostname:SC> console c
Connected to Domain C
Domain Shell for Domain C
schostname:C> setkeyswitch off

5.  Power off all the remaining components on your Sun Fire  6800 and/or Sun Fire E6900 Server(s) via the "poweroff all" command from the platform shell.
schostname:C> disconnect
schostname:SC>
schostname:SC> poweroff all

This completes the software piece of the powerdown procedure.
6.  Now we will strictly be performing hardware (physical) procedures. On your Sun Fire 6800 and/or Sun Fire E6900 Server(s), turn the keyswitch on the Frame Manager located at the top-most portion of the chassis to the "off" position.

7.  Next, turn off the 2 AC input box switches located at the middle rear (left and right) portion of the system chassis.

8.  Lastly, turn off the 4 Redundant Transfer Switches (RTS) towards the bottom-most portion of the system chassis (2 in the front and the other 2 in the back).

Congratulations! This completes the safest and recommended way of completely powering down your Sun Fire 6800 and/or Sun Fire E6900 Server(s).


Power Up Procedure:

"Bottom-To-Top" Sequence:

1.  First, on your Sun Fire 6800 and/or Sun Fire E6900 Server(s) turn on the 4 Redundant Transfer Switches (RTS) towards the bottom-most portion of the system chassis (2 in the front and the other 2 in the back). Allow 30 seconds to one minute for the RTS modules to completely power on.

2.  Next, turn on the 2 AC input box switches located at the middle rear (left and right) portion of the system chassis.

3. Then, on your Sun Fire 6800 and/or Sun Fire E6900 Server(s), turn the keyswitch on the Frame Manager located at the top-most portion of the chassis to the "on" position. This will allow the system controllers to boot up that will in turn supply the clock signals and (platform and domain) management capabilities.
This completes the hardware (physical) piece of the powerup procedure.
@ Internal Comments

This document was created as a direct feedback from customers who find it difficult to search
several various documentations (such as Field Service Manuals and Administration Guides) that
do not provide detailed procedures in one "common" easy to reference documentation.
