Install the required IAM roles if needed

To operate post-launch actions and allow to run SSM documents on launched instances, certain IAM roles must be installed. Usually these roles are installed into an AWS account when AWS DRS is initialized in the account for the first time in any region.

If you have already initialized Elastic Disaster Recovery in your account before September 13, 2023, it's possible that the required IAM roles were not installed in your account.

To verify the IAM roles are installed or install them if not installed (a one time operation, go to Settings → Default post-launch actions and check Post-launch actions settings. If you see the message Install the required IAM roles to allow using post-launch actions select Install post-launched IAM roles. If the roles were installed successfully, the message to install the roles is not present in Post-launch actions settings.
