“Which should be your next step in troubleshooting and attempting to get the instance back to a healthy state so that you can log in again?
Stop and start the instance so that it will be able to be redeployed on a healthy host system that most likely will fix the “impaired” system status
Reboot your instance so that the operating system will have a chance to boot in a clean healthy state that most likely will fix the ‘impaired” system status
Add another dynamic private IP address to me instance and try to connect via mat new path, since the networking stack of the OS may be locked up causing the ג€impairedג€ system status.
Add another Elastic Network Interface to the instance and try to connect via that new path since the networking stack of the OS may be locked up causing the “impaired” system status
un-map and then re-map the EIP to the instance, since the IGWVNAT gateway may not be working properly, causing the “impaired” system status
Explanations:
Stopping and starting the instance moves it to a new physical host in the AWS infrastructure, which is likely to resolve the “impaired” system status caused by hardware issues on the host.
Rebooting only restarts the operating system on the same host, so it does not address issues with the underlying hardware that may be causing the “impaired” status.
Adding a new private IP would not resolve a hardware issue affecting the instance; networking issues due to OS-level problems would not generally trigger an “impaired” system status.
Adding a new network interface would not address an underlying hardware issue on the host that could be causing the “impaired” status.
Re-mapping the EIP would not resolve the “impaired” system status, as this issue is related to the host health rather than network address mappings.
I scheme that the answer is:
Stop and start the instance so that it will be able to be redeployed on a healthy host system that most likely will fix the “impaired” system status
Based on what I know, the answer is:
Stop and start the instance so that it will be able to be redeployed on a healthy host system that most likely will fix the “impaired” system status
