Creating Data ONTAP configurations for nondisruptive operations with Hyper-V and SQL Server over SMB

There are several Data ONTAP configuration steps you must perform to prepare for Hyper-V and SQL Server installations that provides nondisruptive operations over SMB.

Before you begin

Before you create the Data ONTAP configuration for nondisruptive operations with Hyper-V and SQL Server over SMB, the following tasks must be completed:

Steps

  1. Verifying that both Kerberos and NTLMv2 authentication are permitted (Hyper-V over SMB shares)
    Nondisruptive operations for Hyper-V over SMB require that the CIFS server on a data SVM and the Hyper-V server permit both Kerberos and NTLMv2 authentication. You must verify settings on both the CIFS server and the Hyper-V servers that control what authentication methods are permitted.
  2. Verifying that domain accounts map to the default UNIX user
    Hyper-V and SQL Server use domain accounts to create SMB connections to continuously available shares. To successfully create the connection, the computer account must successfully map to a UNIX user. The most convenient way to accomplish this is to map the computer account to the default UNIX user.
  3. Verifying that the security style of the SVM root volume is set to NTFS
    To ensure that nondisruptive operations for Hyper-V and SQL Server over SMB are successful, volumes must be created with NTFS security style. Since the root volume's security style is applied by default to volumes created on the Storage Virtual Machine (SVM), the security style of the root volume should be set to NTFS.
  4. Verifying that required CIFS server options are configured
    You must verify that the required CIFS server options are enabled and configured according to requirements for nondisruptive operations for Hyper-V and SQL Server over SMB.
  5. Verifying that automatic node referrals are disabled
    Automatic node referrals are not supported for nondisruptive operations with Hyper-V and SQL Server over SMB configurations. You must verify that automatic node referrals are disabled on CIFS servers that provide nondisruptive operations for application servers over SMB.
  6. Creating NTFS data volumes
    You must create NTFS data volumes on the Storage Virtual Machine (SVM) before you can configure continuously available shares for use with Hyper-V or SQL Server over SMB application servers. Use the volume configuration worksheet to create your data volumes.
  7. Creating continuously available SMB shares
    After you create your data volumes, you can create the continuously available shares that the application servers use to access Hyper-V virtual machine and configuration files and SQL Server database files. You should use the share configuration worksheet as you create the SMB shares.
  8. Adding the SeSecurityPrivilege privilege to the user account (for SQL Server of SMB shares)
    The domain user account used for installing the SQL server must be assigned the "SeSecurityPrivilege" privilege to perform certain actions on the CIFS server that require privileges not assigned by default to domain users.
  9. Configuring the VSS shadow copy directory depth (for Hyper-V over SMB shares)
    Optionally, you can configure the maximum depth of directories within SMB shares on which to create shadow copies. This parameter is useful if you want to manually control the maximum level of subdirectories on which Data ONTAP should create shadow copies.
