SolutionSteps to FollowPlease make sure to follow each step in the order in which it is presented. The instructions for a Sun Fire[TM] E2900, V1280 and Netra[TM] 1280, 1290 are highlighted separately as they employ Lights Out Management(LOM) instead of the System Controller(SC) employed by the Serengeti/Amazon class of servers. Instructions for Platforms employing the System controller(SC) 1. Ensure that the domain is actually hung: - Can you ping the domain? 2. Ensure that the SC (System Controller) is not hung, If you can access the System Controller, proceed to login to the SC and obtain a platform shell. A.If you get to the platform shell run the following commands: SCname:SC> showlogs B. If the SC is hung See Document 1002033.1 for details on how to recover from a hung system controller. Then go back to step 2A. 3. Once in the platform shell attempt to get a domain shell: SCname:SC> console -d - If the command appears to hang, then we need to send a break signal to the domain. - if you are using telnet: Press CTRL ] - if you are connected to the SC via tip: use ~# At this point you should have a domain shell prompt, continue with the following commands, otherwise continue to step 4. - If you get the domain shell run the following commands:
4. If you were not able to get to the ok prompt, then the system is really hung and we will need to send an XIR (externally initiated reset) to the domain. From the domain shell type: reset This command will give different behavior depending on what the OBP {#} ok dump-sigblock - If you were not able to return to the ok prompt, but have a domain prompt type the following command: SCname:A> showresetstate 5. If none of these tactics work you may be forced in to just powering off the domain. If this is the case then do a setkeyswitch off for the domain. Instructions for Platforms employing Lights Out Management(LOM) 1. Ensure that the domain is actually hung: - Can you ping the domain? 2. Login to the LOM prompt via telnet/ssh or tip. A. once you get the lom prompt, run the following commands: lom>showsc -v 3. Try to connect to the domain and see what state it is in: A. use the console commands to connect to domain lom> console B. If there's no response from console, use escape sequence to break out. lom>console C. Once the domain is confirmed to be un-reachable, go to next step. 4. Using the 'break' or 'reset' command to recover. A. Try to break into the OBP by 'break' and if you get to OBP, lom>break This will suspend Solaris. {3} ok sync B. If 'break' does not work, a 'reset' has to be used lom>reset This will abruptly terminate Solaris. lom>showresetstate 5. If none of the procedures above work, a poweroff/poweron needs to be issued. lom> poweroff all Product Sun Fire 6800 Server Sun Fire 4810 Server Sun Fire 4800 Server Sun Fire 3800 Server Sun Fire E6900 Server Sun Fire E4900 Server Sun Fire E2900 Server Sun Fire V1280 Server Internal Comments Audited/updated 11/05/09 - [email protected], Mid-Range Server Content Team NOTE: Procedures given in this document are dependant on OBP and SC versions System Controller, SC, Sun Fire, Serengeti, kernel, XIR Previously Published As 46780 Change History Date: 2008-11-19 User Name: T230884 Action: Quality Review Date: 2007-06-04 User Name: 97961 Action: Approved Comment: - Fixed STM formatting warnings/issues Version: 11 Date: 2007-06-04 User Name: 97961 Action: Accept Attachments This solution has no attachment |
