Stack creation failure message encountered

In the AWS CloudFormation Events tab, the reason for stack creation failure is described as follows:
The maximum number of addresses has been reached.

You might encounter this error if you try to deploy two clusters in an AWS region by using the default root or IAM user account settings, but you have insufficient elastic IP addresses available for the AMI deployment. The IBM Spectrum Scale™ deployment requires three elastic IP addresses. You can deploy the IBM Spectrum Scale offering on AWS in a different AWS Region where you are not using elastic IP addresses, or you can use one of the following approaches:

  • For the region in which you are hitting a failure to allocate elastic IPs, request a limit increase for your elastic IP limit.
  • If you have elastic IP addresses allocated that you do not need, delete some of these addresses. Deleting unneeded addresses frees up the elastic IP addresses available in the region where you intend to launch IBM Spectrum Scale.
