This articles provides a data collection plan when troubleshooting locked down or offline E-Series controllers in all supported releases. Note that some of the data may not be available in certain lock down conditions.
Answer
- Check and document the 7-segment display codes on the back of the controller(s). Expect 2 or more codes from each controller.
- Collect Support Bundle from the online controller.
- Name the files with the system name, data type, system state, and date.
- i.e. DR_CSB_Lockdown_3-30-2020.7z
- Name the files with the system name, data type, system state, and date.
- Capture data (if possible) from the locked down controller. If both controllers are locked down then the below data must be captured from both.
- Start a serial shell capture and run the following commands: Make sure logging is enabled for the console/serial session
- cmgrShow
- excLogShow
- hwLogShow
- spriSevenSegShow
- getRecoveryFailureList_MT
- lockMgrShow (from both controllers)
- Current Debug Queue data (if possible): dqprint "trace". Full Debug Queue data (historic trace buffers) should be collected after the system is recovered.
- If the controller is in lockdown. Clear the lockdown to capture the start-of-day boot up process.
- Make sure logging is enabled for the console/serial session
- Run following commands in the below order to clear lock down:
- clearHardwareLockdown
- lemClearLockdown
- Run following commands in the below order to clear lock down:
- Clearing the lockdown may clear the condition and allow the controller to return to optimal.
- If the controller returns to the locked down state then follow recovery steps for the specific 7-segment code documented in NetApp Knowledgebase database.
- Make sure logging is enabled for the console/serial session
- Start a serial shell capture and run the following commands: Make sure logging is enabled for the console/serial session
