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.
About this task
Automatic node referrals are disabled by default. If you have enabled them on the CIFS server that will provide nondisruptive services over SMB shares, you must disable them.
Steps
- Perform the following to verify that automatic node referrals are disabled on the CIFS server:
- Set the privilege level to advanced: set -privilege advanced
- Verify that the -is-referral-enabled CIFS server option is set to false: vserver cifs options show -vserver vserver_name -fields is-referral-enabled
- If automatic node referrals are not disabled, perform the following:
- Disable automatic node referrals: vserver cifs options modify -vserver vserver_name -is-referral-enabled false
- Verify that the new setting is correct: vserver cifs options show -vserver vserver_name -fields is-referral-enabled
- Return to the admin privilege level: set -privilege admin
Example
The following commands verify that automatic node referrals are disabled on Storage Virtual Machine (SVM, formerly known as Vserver) vs1:
cluster1::> set -privilege advanced
Warning: These advanced commands are potentially dangerous; use them
only when directed to do so by technical support personnel.
