Issue

API call to /api/private/cli/system/node/virtual-machine/instance/show-settings returns expected storage_capacityvvalue after FSXn instance creation or expansion

After shrinking FSXn instance, storage_capacity value in API response does not decrease

Example API response shows storage_capacity remains at previous higher value after instance is reduced

Data Infrastructure Insights licensing impacted due to incorrect sizing input from API

Example:

$ curl -X GET "https://10.1.2.3/api/private/cli/system/node/virtual-machine/instance/show-settings?fields=node,consumer,storage_type,storage_capacity,iops,throughput_capacity" \
-u "user@pass" \
-H "Accept: application/json" \
-k
