Why Do I Fail to Create a DCS Redis Instance?

  • The subnet does not have sufficient IP addresses.

    Analysis: Each node in a DCS instance must be assigned an IP address. Therefore, a single-node instance requires one IP address, a master/standby instance requires two IP addresses, and a cluster instance requires multiple IP addresses.

    Solution: Create the instance in a different subnet or release IP addresses in the current subnet.

  • The IAM user does not have the permissions required to create an instance.

    Analysis: The group to which the user belongs must be granted the DCS FullAccess policy or DCS Administrator role or other policies containing the permissions required for creating DCS instances.

    Solution: Create a DCS instance as the administrator.
