 - `pi_storage_pool_affinity` - (Optional, Bool) Indicates if all volumes attached to the server must reside in the same storage pool. The default value is `true`. To attach data volumes from a different storage pool (mixed storage) set to `false` and use `pi_volume_attach` resource. Once set to `false`, cannot be set back to `true` unless all volumes attached reside in the same storage type and pool.
 - `pi_storage_type` - (Optional, String) - Storage type for server deployment. Only valid when you deploy one of the IBM supplied stock images. Storage type for a custom image (an imported image or an image that is created from a VM capture) defaults to the storage type the image was created in
 - `pi_storage_connection` - (Optional, String) - Storage Connectivity Group (SCG) for server deployment. Only supported value is `vSCSI`.
-- `pi_sys_type` - (Optional, String) The type of system on which to create the VM (s922/e880/e980).
-  - Required when not creating SAP instances. Conflicts with `pi_sap_profile_id`.
+- `pi_sys_type` - (Optional, String) The type of system on which to create the VM (s922/e880/e980/e1080/s1022).
+  - Supported SAP system types are (e880/e980/e1080).
 - `pi_user_data` - (Optional, String) The base64 encoded form of the user data `cloud-init` to pass to the instance during creation. 
 - `pi_virtual_cores_assigned`  - (Optional, Integer) Specify the number of virtual cores to be assigned.
 - `pi_volume_ids` - (Optional, List of String) The list of volume IDs that you want to attach to the instance during creation.
