Simulate_ONTAP_8.3 Cluster Mode: CIFS Server/Shares not accessible.

caminosoft — Wed, 04 Jun 2025 22:27:37 GMT

Forgive me, I am not a NetApp person. I'm setting up a virtual simulator for my developers to do their thing in creating functionality for their software...very simple setup for them...

The problem I am having is I cannot access my CIFS shares on the CIFS Server from anywhere on my network

External virtual systems are:

VMWare ESXi 6
Windows 2012 A/D, DNS, DHCP

I've been successful with the following...

Creating Single node cluster (all that is required).
Creating Second aggregate
Creating SVM with assigned subnet/nic
Creating vols on SVM
Configuring the SVM for CIFS (added to Windows 2012 AD domain)

I cannot see the CIFS server nor it's shares...even the C$.

To me it appears the shares are not properly being shared out by Winders.

Any assistance would be appreciated...

Difficult to figure out the problem unless we have more details.

I would recommend to follow the below guides provide in the link @ http://mysupport.netapp.com/documentation/docweb/index.html?productID=61689

Clustered_Data_ONTAP_82_CIFSSMB_Server.pdf

Clustered_Data_ONTAP_82_SMB_File_Access_Express.pdf

The above link and guides are for 8.2. For 8.3, follow @ http://mysupport.netapp.com/documentation/docweb/index.html?productID=61885

These are express guides (which are few 10s of pages) which provide a quick n easy way to setup CIFS in clustered Data ONTAP.

Thanks,

I'll review and report back when finished...

A few things to check:

1. Make sure the time in the sim matches the time on your domain

2. Be sure you are using different names for each SVM you configure CIFS for when you join it to AD. A computer account is created for the SVM and they need to be unique.

3. You may need to create DNS entries so your clients can find the SVM.

Sean,

Thanks for the suggestions...

Sim time matches domain time.
Only need the one... So always using unique name for each SVM configuring CIFS for joining to AD.
I manually go in and add the DNS entry. Can ping the IP addy as well as the dns name

I don't think I'm terribly off on this. But I did find an interesting "anomaly"

My developer creates his vserver with an "NIS Switch" (vserver create -vserver camino-02 -rootvolume root_vs0 -aggregate aggr1 -ns-switch nis -rootvolume-security-style ntfs -language C.UTF-8)

Not sure NIS Switch / Domain is actually necessary in this case. I've had this all setup successfully before without them and was able to map drives to the shares. I say that because by enabling diag trace logging (diag secd trace set -node local -trace-all yes), I was finally able to get an event log after failing to map to the volumes...
Not sure it's the user mapping. Have not needed it is successful attempts before. That leaves the question of NIS within this rabbit hole.

Greatly appreciated...

An incorrect NIS configuration can prevent CIFS from working. If NIS is configured on the SVM make sure the nis domain and nis server are valid, and the nis server is operational. If NIS is not in use, then either ommit nis from the ns-switch option or place it at the end of the list (file,nis). In this case the nisdomain should be blank.

Thanks for the help. I believe I got it. I compared the creation of the SVM via command line with the NIS options against the SVM creation via the OnCommand GUI and noticed a difference in the way the nis was being enabled. So I will revisit the nis options during creation on another lab simulator to determine the correct syntax.

All volumes/shares are now available on the network as expected.

Thanks.
