Applies to:Sun Fire 3800 ServerSun Fire 4800 Server Sun Fire 4810 Server Sun Fire 6800 Server Sun Fire E4900 Server All Platforms GoalThis document describes the preparation steps to prepare your configuration for a System Controller replacement on Sun Fire[TM] 3800, 4800, 4810, E4900, 6800, and E6900 systems.The System Controller (SC) is not customer serviceable. An Oracle badged engineer is required to perform the physical replacement of this component. The preparation steps, however, can and should be performed by a system administrator so that the system is in a state where the field engineer can complete the physical replacement activity as quickly as possible. DISCLAIMER: This document is to be used as a reference only. It does not replace or super-cede the appropriate sections of the Platform Administration Manual or System Service Manual. Resources:
SolutionPre-Replacement (A customer or Sys Admin should perform this.):1. Issue a "showplatform" command on the SC that needs to be replaced and keep the network and host information.
2. Issue a showsc command on the SC that needs to be replaced and make note of the status of the SC and the firmware version installed. For the following procedure, System Controller 1, "sc1", is the unit to be replaced and in this case it is running ScApp 5.15.3. sc1:sc> showsc 3. Make sure the SC to be replaced is the spare (as highlighted above).
4. When able to shut down the SC, perform the following:
An Oracle badged engineer is now required to perform the physical replacement of the SC.The Oracle engineer will follow the replacement procedure document in the Sun Fire E6900/E4900 Systems Service Manual (pdf). The new system controller should start to boot when plugged in. It is important to connect to the new SC via the serial port and validate that SSC_POST executes without issues. If errors are seen during SSC_POST or it fails contact support services or troubleshoot the event with the Oracle Engineer who should still be onsite through this stage in the process. Post-Replacement (A customer or Sys Admin can perform this, but the Oracle Engineer may assist in these steps as well)1. Issue the command showsc on the new controller and see if the firmware matches the version from Pre-replacement data.
3. The SC will reboot to start up utilizing the new firmware version after it is updated. 4. Issue the command setfailover on from the Main SC. This enables SC Failover and synchronizes the new SC with the platform configuration information contained on the existing Main SC.5. You should see the following message on the spare SC: Platform.SC: SC Failover: enabled but not active, System controller needs to be rebooted.Reboot the new/spare SC. 6. Once the new SC boots, run showsc again and check the date and time, and confirm the IP addresses are as expected. Post-replacement Checks:1. Login to both the Main and spare SC and run the command showfailover.Make sure they both reflect: SC Failover: enabled active.2. Run the command showkeyswitch from the Main SC and make sure all domains are on (or as expected if some domains were not active). 3. Check network connections and make sure you can login to the SCs via network (if configured). 4. If time allows (or desired) issue a setfailover force from the Main SC to test SC failover. This will validate that the new SC can function as the Main SC.
