[leenaj0hn]

When type is full:
"msg": "Volume creation failed | Bad request (HTTP 400) - invalid input: Either tpvv must be true OR for compressed and deduplicated volumes both 'compression' and 'tdvv' must be specified as true"

"msg": "Volume creation failed | Bad request (HTTP 400) - invalid input: On Primera for tpvv volume, 'type' must be set to thin, and for compressed and deduplicated volumes 'compression' must be set to true and 'type' must be specified as thin_dedupe"

type:thin_dedupe compression:false

"msg": "Volume creation failed | Bad request (HTTP 400) - invalid input: For compressed and deduplicated volumes both 'compression' and 'tdvv' must be specified as true"

}

"msg": "Volume creation failed | Bad request (HTTP 400) - invalid input: For compressed and deduplicated volumes 'compression' must be specified as true" and type value should be thin_dedupe

}

convert from thin and compression=false to thin and compression set to true

"msg": "Provisioning type change failed | Bad request (HTTP 400) - invalid input: On primera supported array along with compression set to true 'conversionOperation' must be 3(TDVV) or for deco operation user can set 'conversionOperation' to 4(CONVERT_TO_DECO)"

"msg": "Provisioning type change failed | Bad request (HTTP 400) - invalid input: On primera array, with compression set to true 'conversionOperation' must be have type set to "thin_dedupe"
