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.
-
SMB 2.x and SMB 3.0 must be enabled.
-
ODX copy offload must be enabled to use performance enhancing copy offload.
-
VSS Shadow Copy services must be enabled if the Hyper-V over SMB solution uses Remote VSS-enabled backup services (Hyper-V only).
-
Verify that the required CIFS server options are enabled on the storage virtual machine (SVM):
-
Set the privilege level to advanced:
set -privilege advanced
-
Enter the following command:
vserver cifs options show -vserver vserver_name
The following options should be set to
true
:-
-smb2-enabled
-
-smb3-enabled
-
-copy-offload-enabled
-
-shadowcopy-enabled
(Hyper-V only)
-
-
-
If any of the options are not set to
true
, perform the following:-
Set them to
true
by using thevserver cifs options modify
command. -
Verify that the options are set to
true
by using thevserver cifs options show
command.
-
-
Return to the admin privilege level:
set -privilege admin
The following commands verify that the required options for the Hyper-V over SMB configuration are enabled on SVM vs1. In the example, ODX copy offload must be enabled to meet the option requirements.
