Parameters 

Parameter	Comments
adv_host_mgmt_enabled boolean	If `false`, allows you to specify hosts without first having to register them. Mandatory while adding access hosts. Choices: `false` `true`
anonymous_gid integer	Specifies the group ID of the anonymous account. If not specified at the time of creation, it will be set to 4294967294.
anonymous_uid integer	Specifies the user ID of the anonymous account. If not specified at the time of creation, it will be set to 4294967294.
default_access string	Default access level for all hosts that can access the NFS export. For hosts that need different access than the default, they can be configured by adding to the list. If default_access is not mentioned during creation, then NFS export will be created with `NO_ACCESS`. Choices: `"NO_ACCESS"` `"READ_ONLY"` `"READ_WRITE"` `"ROOT"` `"READ_ONLY_ROOT"`
description string	Description of the NFS export. Optional parameter when creating a NFS export. To modify description, pass the new value in description field. To remove description, pass the empty value in description field.
filesystem_id string	ID of the filesystem. This is a unique ID generated by Unity storage system.
filesystem_name string	Name of the filesystem for which NFS export will be created. Either filesystem or snapshot is required for creation of the NFS. If filesystem_name is specified, then nas_server is required to uniquely identify the filesystem. If filesystem parameter is provided, then snapshot cannot be specified.
host_state string	Define whether the hosts can access the NFS export. Required when adding or removing access of hosts from the export. Choices: `"present-in-export"` `"absent-in-export"`
min_security string	NFS enforced security type for users accessing a NFS export. If not specified at the time of creation, it will be set to `SYS`. Choices: `"SYS"` `"KERBEROS"` `"KERBEROS_WITH_INTEGRITY"` `"KERBEROS_WITH_ENCRYPTION"`
nas_server_id string	ID of the NAS server on which filesystem will be hosted.
nas_server_name string	Name of the NAS server on which filesystem will be hosted.
nfs_export_id string	ID of the nfs export. This is a unique ID generated by Unity storage system.
nfs_export_name string	Name of the nfs export. Mandatory for create operation. Specify either nfs_export_name or nfs_export_id (but not both) for any operation.
no_access_hosts list / elements=dictionary	Hosts with no access to the NFS export. List of dictionaries. Each dictionary will have any of the keys from host_name, host_id, subnet, netgroup, domain and ip_address. If adv_host_mgmt_enabled is `true` then the accepted keys are host_name, host_id and ip_address. If adv_host_mgmt_enabled is `false` then the accepted keys are host_name, subnet, netgroup, domain and ip_address.
domain string	DNS domain, where all NFS clients in the domain are included in the host list.
host_id string	ID of the host.
host_name string	Name of the host.
ip_address string	IP address of the host.
netgroup string	Netgroup that is defined in NIS or the local netgroup file.
subnet string	Subnet can be an ‘IP address/netmask’ or ‘IP address/prefix length’.
password string / required	The password of the Unity management server.
path string	Local path to export relative to the NAS server root. With NFS, each export of a file_system or file_snap must have a unique local path. Mandatory while creating NFS export.
port integer	Port number through which communication happens with Unity management server. Default: `443`
read_only_hosts list / elements=dictionary	Hosts with read-only access to the NFS export. List of dictionaries. Each dictionary will have any of the keys from host_name, host_id, subnet, netgroup, domain and ip_address. If adv_host_mgmt_enabled is `true` then the accepted keys are host_name, host_id and ip_address.

subnet string	Subnet can be an ‘IP address/netmask’ or ‘IP address/prefix length’.
read_only_root_hosts list / elements=dictionary	Hosts with read-only for root user access to the NFS export. List of dictionaries. Each dictionary will have any of the keys from host_name, host_id, subnet, netgroup, domain and ip_address. If adv_host_mgmt_enabled is `true` then the accepted keys are host_name, host_id and ip_address.
