Unable to Attach Additional Volume to Instances

Issue

• We have a requirement to attach 5 volumes to our DB instances. Currently, 4 volumes (including the OS disk) are already attached. However, when attempting to attach the 5th volume, we encounter the following error:

Unable to attach volume. DetailsThe maximum allowed number of disk devices (4) to attach to a single instance has been exceeded. (HTTP 403) (Request-ID: req-8dad39cc-3afa-4cef-b527-b2ead83738b5)

• Please investigate this issue and check the possibility of increasing the limit for these instances. Let us know if any configuration changes are required from our side.
