EC2 P3 instance with 16Gib Volume

Hello Kerly Cervantes,

• The size of the EBS volume is not based on the EC2 instance size; it's based on the AMI (Amazon Machine Image) you are using to launch the instance. Please provide the minimum required size for your AMI and specify at least that size.
• By using this AWS CLI command, you can find the required size for the image in GiBs

aws ec2 describe-images --image-ids ami-xxxxxxxxx --query 'Images[0].BlockDeviceMappings[0].Ebs.VolumeSize'

• If you specified an EBS size less than required for the AMI, you will see something like this:

• You may encounter the InsufficientInstanceCapacity error when the AWS region or availability zone you have chosen lacks the necessary On-Demand capacity to provision the requested P3 instances with your specified requirements. This situation arises due to a shortage of available resources that match your instance configuration in the selected deployment area.

I don't believe the message you are seeing refers to storage but rather that there is not capacity of P3 instances at this time.

Try the following:

• choose a subnet in a different AZ
• launch in another region
• wait some time and try again

If none of the resolve your issue, you should open a support case for assistance.
