Managing license keys

License keys add powerful services to the storage server, and they can be purchased and added whenever needed. A License Certificate identifies all of the purchased services and should be kept in a safe place. The License Certificate is included in the User Documentation Wallet that was shipped with the system.

System Administrators manage keys for licensed services from the License Keys page, which displays the status (and features enabled by) each key and provides controls for adding and deleting keys.


  1. Navigate to Home Server Settings License Keys to display the License Keys page.

    NoteThe list of licenses presented on your screen may differ from the page shown.

    Field/Item Description
    File License Keys
    MAC ID The MAC ID of the server/cluster. This is used for requesting file licenses.
    License Key The alphanumeric string that is the license key.
    Cluster Only displayed for a cluster, this is the maximum number of nodes licensed. This indicates the maximum number of servers that can be configured as nodes of a cluster. Note that cluster licenses are handled somewhat differently than other licenses
    EVS The maximum number of EVSs allowed on the server/cluster. The options are 0 to 64 inclusive.
    Storage Capacity The maximum amount of storage allowed for the server/cluster. Note that the amount of licensed storage must be equal to or greater than the total amount of storage in all subsystems connected to the storage server or cluster.
    Universal NAS Virtual Capacity The maximum amount of Universal NAS Virtual Capacity storage allowed for the server/cluster.
    Model Type Allows a NAS Platform 4060 to be upgraded to a NAS Platform 4080.
    Expires The expiration date for each key, if the key expires (expired license keys are shown in grey).
    Total Licensed on All Unexpired Keys Displays a list of all services enabled by all installed keys.
    details To display more details about a particular license key, click details.
    Check All Selects the check box next to each key.
    Clear All Clears the check box next to each key.
    add file license Displays the License Key Add page.
    delete Select the check box next to a key, then click delete to remove the key from the server/cluster.
    CautionUse extreme care when deleting a license key. Removing the selected license could affect services running on the server.
    Show licensed services To see the services licensed by a particular key, select the check box next to the key and click Show licensed services. A check mark appears next to the relevant licensed services.
    Block License Keys
    S/N The serial number of the block chassis. This is used for requesting block licenses.
    Product Name The list of available software licenses for the Block-portion of the server.
    Status Displays the installation status of the software license.

    The options are:

    • Installed - The software license is installed and available for use.
    • Installed (Disabled) - The software license is installed but an error has occurred or a license for a prerequisite application has expired.
    • Not installed - The software license is not installed.
    • Not enough License - The software license is installed but the license capacity is insufficient.
    • Grace Period - The licensed capacity is insufficient because storage has been added. The license expires in 30 days.
    • Expired - The term has expired for the license key.
    Key Type The options are:
    • Permanent - Enables use of the software license indefinitely.
    • Term - Enables use of a software license for a specific number of days (see Term below).
    • Temporary - Enables use of a software license for trial purposes for 120 days (see Term below).
    • Emergency - Enables use of a software license for 30 days if it is not possible to access or purchase a more permanent license.
    Capacity Permitted The maximum storage volume capacity permitted for use with the software feature by the license.
    Capacity Used The storage volume capacity currently in use by the licensed feature.
    Term (Days)

    The number of days remaining before the expiration of the Term, Temporary or Emergency license key. After a Temporary key has expired, this field shows the number of days that remain before it is possible to install another Temporary key.

    For a Permanent key, the expiration term is unlimited and a hyphen (-) is displayed.

    add block license Opens the License Key Add page which enables you to install a Block software license.
  2. Review the current license key information.

  3. To add or delete license keys:

    • To add a license key, click add to go to the License Key Add page .
    • To delete a license key, select the check box next to the key to delete, then click delete. It is not possible to delete a block license.

Adding a license key

Adding a license key can enable services or increase the capabilities of your system. To add a license key:


  1. Navigate to Home Server Settings License Keys.

  2. Click add.

    The following table describes the fields on this page:

    Field/Item Description
    Add a File License Key
    File License Key Enables the user to manually enter the license key.
    Import File License Keys From a File
    File License Key File Name Enables the user to import a license key from a file.
    Import Block License Keys From a File (NAS module only)
    Block License Key File Name Enables the user to import a software application license key from a file.
    cancel Closes the page without saving configuration changes.
    NoteAfter adding a license key, if a reboot is required in order to start a service/protocol or enable a feature, you are instructed to reboot or restart the system.
    For a file license, you can either enter the key manually or import it from a file. For a block license, you can only import the key from a file:
    • To enter the key manually, type it in the field, then click add.
    • To import the key, click Choose File / Browse, navigate to the file, select the key file, then click Import.

    After all the keys have been entered or imported, they will be displayed on the License Keys page. Follow the instructions to reboot the system (if necessary).

License types

Licenses can be grouped into three types:

  • Boolean licenses simply enable features/protocols, and when the license is installed the feature/protocol is enabled (for example external volume links, CIFS, or NFS). These licenses operate in a boolean fashion; if the license is present the feature/function is enabled, if not present, the feature/function is disabled.
  • Limit-based licenses specify a limit that cannot be exceeded. These licenses limit your system to a certain total numerical upper limit of the licensed feature/function. For example, the EVS (virtual server) license is a limit-based license.

    Limit-based licenses are not cumulative. For example, if your existing cluster has an EVS license for up to nine EVSs, and you install another EVS license for up to eight EVSs, you still cannot have more than nine EVSs (the highest licensed amount). For more information, contact your support representative.

    NoteA cluster license is a special kind of limit-based license. When a node joins an existing cluster, its cluster license is transferred to the cluster (if necessary).
  • Cumulative licenses. Only the Storage capacity and Universal NAS Virtual Capacity (UNVC)s licenses are cumulative, and several storage capacity licenses can be used to increase the capacity or capability of the system. For example, if you have one storage capacity license for 40 terabytes and another storage capacity license for 60 terabytes, your system could manage up to 100 terabytes of storage.

If a node is removed from a cluster, you must restore its license keys for it to function properly as a standalone server. You should retain the licensing information, in case a node needs to be removed from the cluster.

NoteLicense keys that have been purchased do not expire. Trial licenses, which enable features for use on a trial basis, have a predefined expiration date. Five days before the expiration of a trial license, the server's event log begins receiving a daily warning event, indicating imminent expiration; then, two days before expiration, the warning events escalate to "severe." When a trial license has expired, the features that enabled by the license become disabled.

The following table lists all services that can be licensed:

Service Description
CIFS Common Internet File System. This is a message format used by Windows and MS-DOS to share files, directories, and devices.
Cluster Clustering. Enables the clustering of up to X nodes. The maximum number of nodes supported in a cluster depends on the series of server used as nodes of the cluster.
NoteThe Hitachi Vantara Unified Module allows a maximum of two nodes. The unit itself contains the two nodes. No licensing is required for clusters on this unit.
CNS Cluster Name Space. Creates a virtual name space through which multiple file systems can be made accessible using a single mount point. If the EVS Security license is also installed, you can also create individual EVS Name Spaces.
Premium Deduplication Enables the use of Premium Deduplication, a licensed feature with a four SHA-256 engines, capable of indexing data at a rate of up to 450 MB per second.
NoteA Base Deduplication feature is automatically enabled by default and does not require a license key. This is a dedupe feature with a single SHA-256 engine (capable of indexing data at a rate of up to 120 MB per second).
DM License for Data Migrator, which is required for Classic Data Migrator and for Data Migrator to the Cloud. Data Migrator without XVL allows classic data migration to internal targets. Data Migrator with XVL allows external Classic data migration, that is to HCP (the classic way), and to NFS servers. Data Migrator with XVL allows Data Migrator to the Cloud for any cloud provider. Refer to the XVL license description in this table.
EVS Enables up to X Virtual Servers (EVSs).
EVS Security EVS Security. Allows EVS to have their own settings independent of other EVSs and independent of the whole cluster.
ExtPackSecureFTP License for Extension Pack for Secure FTP. A virtual appliance that provides authenticated access to HNAS content via FTP, FTPS, and SFTP.
FileClone Enables the Writable file clone feature. Refer to the File Services Administration Guide for more information.
FSR File System Rollback. A tool for restoring a file system to the state of its last successful replication.
FSRS File System Recovery from Snapshot. A tool for rolling back one or more files in a file system to a previous version without actually copying the data from a snapshot.
iSCSI Internet Small Computer System Interface. This license enables iSCSI Initiators to communicate at block level with the servers' iSCSI targets.
Model Type ModelType. This license upgrades from NAS Platform 4060 to NAS Platform 4080.
NoteAfter adding the ModelType license, you must restart the server/cluster to make the model change become effective.
NFS Network File System. This is Sun's distributed file system that enables users of UNIX workstations (including Windows NT systems running an NFS emulation program) to access remote files and directories on a network as if they were local.
Read Cache Cluster Read Caching. Enables Read Caching service, which allows one cached read-only file system per EVS.
NoteAfter adding the Read Cache license, you must restart the server/cluster before you can use the read cache.
Replication Replication. Enables replication to external servers (other storage servers, clusters, or an NFS server).

This license is required to enable any form of replication outside the server or cluster, including accelerated data copy (ADC). This means that, without a replication license, you can use replication within a server/cluster (you can replicate within an EVS or to a different EVS hosted by the same server/cluster), but you cannot replicate to an external server/cluster.

NoteThe replication license is enforced at the replication source. However, in order to reverse a replication, the source and the target must each have a replication license.
SFM Server Farm Migration of Virtual Servers. Enables migration of Virtual Servers (EVSs) between servers in a Server Farm.
SyncDR Synchronous Disaster Recovery Cluster. Indicates if the server/cluster is authorized to use a stretched cluster configuration. (This is a special configuration. Contact Hitachi Vantara Support Center for more information.)
TB Terabytes. Enables the management of up to "X" terabytes of storage.
Universal NAS Virtual Capacity (UNVC) (Terabytes) License for <n> TB of virtualization storage. Range is from 1 to 32767 TB of storage, or the value "Max". Max is represented with the numeric value of 32768, but it is to be interpreted as whatever maximum value HNAS supports. This license affects the virtualization of third-party NAS storage
XVL External Volume Links. License for XVL. This is cross volume links outside of an EVS, potentially to a third-party machine such as HCP (also known as HCAP) or to an NFS server. Refer to the DM license description in this table for more information.
