Faliures for F1 instance i-079d1265d12d9076f

Question

On occasion, we experience failures of AWS F1 instances.

I have a design running on F1 instances that works reliably.

However, in the past few weeks, we have noticed some instances fail.  The latest failure is for:
  i-079d1265d12d9076f

When start a new instance, the FPGA functions as expected.

How do we track defective F1 instances?

re:Post Agent · Answer

While F1 instances are generally reliable, occasional failures can occur. To track and troubleshoot issues with F1 instances, including potentially defective ones, you can follow these steps:

1. Monitor instance status checks: Use the Amazon EC2 console to review the status checks for your F1 instances. Navigate to the Instances section, select your instance, and check the "Status and alarms" tab. This will show you the results of system status checks, instance status checks, and attached EBS status checks.

2. Review system logs: Collect and analyze system logs from the failed instances. For Linux-based F1 instances, you can use the EC2Rescue for Linux feature to access the instance and gather logs. This tool is pre-installed and allows you to troubleshoot and repair instances directly from the AWS Management Console or AWS CLI.

3. Use EC2 Serial Console: For more in-depth troubleshooting, you can access the EC2 Serial Console to investigate boot and runtime issues that may not be visible through other means.

4. Monitor CloudWatch metrics: Set up CloudWatch alarms to track key performance metrics for your F1 instances. This can help you identify potential issues before they lead to failures.

5. Keep records: Maintain a log of instance IDs that have experienced failures, along with any error messages or symptoms observed. This can help identify patterns or recurring issues.

6. Contact AWS Support: If you notice a trend of failures or suspect that specific F1 instances are defective, it's advisable to contact AWS Support. They can provide more detailed information about the health of the instances and investigate any potential hardware issues.

7. Consider using newer instance types: If you're experiencing recurring issues with F1 instances, you might want to evaluate using F2 instances instead, as they are the newer generation and may offer improved reliability.

By implementing these tracking and troubleshooting methods, you can better identify and address issues with F1 instances, including potentially defective ones. Remember to always keep your FPGA Developer AMI up-to-date and ensure that your account has the necessary quotas and permissions for F1 instances.
