NetApp ONTAP Prerequisites

Last Updated16 February 2024
  1. ONTAP Version Requirements:
    1. For SMB workloads, the minimum required version of clustered Data ONTAP (cDOT) is v8.2.  Older versions of cDOT will not function properly.  ONTAP 9 and above are supported, as well as Cloud Volumes ONTAP and ONTAP Select.
    2. For NFS workloads, the minimum required version of ONTAP is v9.  Cloud Volumes ONTAP and ONTAP Select are supported.  PeerSync is not supported for NFS workloads.

  2. Any server that will be interfacing with a Storage Virtual Machine (SVM) through a Peer Agent or PeerSync must reside within the same domain, share the same network segment, and belong to the same subnet as the SVM.  Additionally, the network connection between the SVM and the Agent or PeerSync must operate at speeds of at least 1 Gbit/sec with sub-millisecond latency.

  3. Server OS Version Requirements:
    1. For SMB workloads, the minimum version of Windows required for FPolicy support with the Peer Agent or PeerSync is Windows Server 2016.
    2. For NFS workloads, the Peer Agent must be installed on Ubuntu Server 22.04 operating system or later, or Red Hat Enterprise Linux v8.8 or later.  PeerSync is not supported for NFS workloads.

  4. SMB Multichannel Requirement:  SMB Multichannel Support must be disabled on the SVM.

    CODE
    set -priv diag
    cifs options modify -vserver <SVM Name> -is-multichannel-enabled false

    All client connections to the SVM must be reset once this change is made on the SVM.

  5. NFS Protocol Version Requirements:  Clients must exclusively use NFSv3 or NFSv4 for accessing data. NFSv4.1 and pNFS are not supported by FPolicy.
  6. The FPolicy Server hosting the Peer Agent or PeerSync can only work with a single SVM at a time.

  7. The server hosting the Peer Agent or PeerSync should not run any other products based on the FPolicy or VSCAN from Peer Software or any other vendor.  In addition, no other Peer Software products can be run on this server (such as Peer Management Center or Peer Management Broker).

  8. Infinite Volumes are not supported.  FlexGroups are supported with ONTAP 9.4 and above.

  9. The DNS name of the SVM must resolve to the IP address of the data LIF(s) used for file access.

  10. Privileges and Permissions for SMB Workloads:
    1. CIFS Permissions:  The service account for the Peer Agent or PeerSync must be a member of the Local Admin Group on the SVM.  To add the service account <Domain User Name> (in the format "DOMAIN\USERNAME") to the Local Admin Group of SVM <SVM Name>, run the following ONTAP command from the cluster context: 

      CODE
      vserver cifs users-and-groups local-group add-members -vserver <SVM Name> -group-name BUILTIN\Administrators -member-names <Domain User Name>
    2. CIFS Privileges:  To properly query and set DACLs, SACLs, owner and/or group configurations on files and folders, the service account for the Peer Agent or PeerSync must be granted special privileges.  To grant these privileges to the account <Domain User Name> (in the format "DOMAIN\USERNAME") on SVM <SVM Name>, use the following ONTAP command from the cluster context:

      CODE
      vserver cifs users-and-groups privilege add-privilege -vserver <SVM Name> -user-or-group-name <Domain User Name> -privileges SeBackupPrivilege,SeRestorePrivilege,SeSecurityPrivilege,SeTakeOwnershipPrivilege,SeTcbPrivilege
  11. Privileges and Permissions for NFS Workloads:  The Peer Agent server IP needs to be granted superuser access in the export policies for any volumes that this Agent will be monitoring, as well as the parents of these volumes in the SVM's namespace.

  12. ONTAPI Access and Service Configuration:  At least one LIF per associated SVM must have management access enabled.  The server running the Peer Agent or PeerSync must be able to communicate with this management LIF.   This management LIF can also serve as a data LIF if desired.

    In ONTAP 9.7 and above, this management LIF must have management-https services set on its service policy configuration.  Customers upgrading from previous versions of ONTAP should have this automatically set upon existing LIFs.

    For example, to set this service on the default-data-files policy of SVM <SVM Name>, run the following ONTAP command from the cluster context in advanced mode (set -privilege advanced):

    CODE
    net int service-policy add-service -vserver <SVM Name> -policy default-data-files -service management-https
  13. FPolicy Service Configuration:  Starting with ONTAP 9.8 and above, one SVM LIF per associated node of the cluster must have the data-fpolicy-client service set on its service policy configuration.  Customers upgrading from previous versions of ONTAP should have this automatically set upon existing LIFs.

    For example, to set this service on the default-data-files policy of SVM <SVM Name>, run the following ONTAP command from the cluster context in advanced mode (set -privilege advanced):

    CODE
    net int service-policy add-service -vserver <SVM Name> -policy default-data-files -service data-fpolicy-client
  14. API Permissions:  The Peer Agent and PeerSync must both be configured with an account on the SVM that has been granted ONTAPI access.  It is recommended that this be a dedicated local account on the associated SVM just for the use of Peer products.  The following ONTAP commands can be executed from the cluster context to create a local account <User Name> with appropriate ONTAP API access on SVM <SVM Name>.

    If you are running PeerGFS v5.2 and above, as well as ONTAP 9.11.1 and above, a new REST-based API model is in place. HTTP support is required for the user account.  You can create this account using the following command:

    CODE
    security login create -vserver <SVM Name> -username <User Name> -application http -authmethod password -role vsadmin

    If you are running PeerSync or an older version of PeerGFS or ONTAP, ONTAPI is still required for the user account.  You can create this account using the following commands:

    CODE
    security login create -vserver <SVM Name> -username <User Name> -application ontapi -authmethod password -role vsadmin  

    Note:  The username and password of this account must be entered into each Peer product as part of the configuration process.
     

  15. The SVM must have a valid certificate installed.
     
  16. No firewalls (software or hardware) should be enabled between the server hosting Peer Agent or PeerSync and the SVM.
