A LIF identify the type of traffic that is supported over the LIF, A LIF can carry traffic any of the below types:

1.Data Traffic

2.InterCluster Traffic

3.Cluster Traffic

4.Cluster Management Traffic

5.Node Management Traffic

The Storage Virtual Machine (SVM) does not have any data LIF configured for CIFS protocol. Create data LIFs before configuring the CIFS server.]

If you are getting above error while enabling protocol on SVM you need to create LIF.

How to create LIF in NetApp using GUI

Click on Network -> Network Interface

Click create

Give Name for LIF

Select interface role -> Here I am selecting for serves data

Select SVM for that you want to create LIF. One LIF can be use for one SVM

Select protocol access -> CIFS, iSCSI, NFS

Assign IP address -> Drop down and select without a subnet one page will prompt to enter IP, Subnet and DG

From port-> expend it and select though with physical interface you want to pass the traffic. Later you can migrate it.

Once you will configure you can't edit it

iSCSI enabled SVM in NetApp ONTAP and mount to Windows and ESXI host

NetApp ONTAP LUN create step by step

NetApp ONTAP NFS volume and mount to ESXI host

NetApp ONTAP SVM create (NFS, CIFS, iSCSI protocol)

NetApp ONTAP LUN create step by step

Expend Storage

Click LUNs

Click Create

Click next

Give LUN Name

OS Type -> Select VMWare

Assign Size -> Next

Select an existing Volume or qtree for this LUN

Browse

Select Volume where you want or create LUN

If you want to create new Volume for LUN

Select Create a new flexible volume

Aggregate Name -> Click choose and select Aggregate name

Volume Name -> Give Volume Name

Click Add Initiator group

Name -> Give Initiator group name

Operating System -> Drop down and select Operating system

Select the Supported protocol for this Group -> iSCSI

Select Initiator Group name give LUN ID -> Next

Check mark manage Storage quality of service if you want to configure

Here I am not configuring. -> Click Next

Click Next

Click Finish

Give Initiator Details i Initiator Group

Click newly created LUN

SVM-> Select iSCSI enabled SVM

Click initiator Groups

Click initiators

enter initiator IQN name and add initiator

Apply and OK

Done with NetApp ONTAP LUN creating steps

now you can MAP LUN in ESXI host ......................

iSCSI enabled SVM in NetApp ONTAP and mount to Windows and ESXI host

NetApp ONTAP LUN create step by step
NetApp ONTAP NFS volume and mount to ESXI host

NetApp ONTAP SVM create (NFS, CIFS, iSCSI protocol)

NetApp ONTAP SVM # iSCSI Volume

iSCSI enabled SVM in NetApp ONTAP and mount to Windows and ESXI host Steps

Expend Storage -> Select SVMs

Click Create

Enter SVM Name

Data Protocol -> Select iSCSI

Security Style -> Drop down and select NTFS

Root Aggregate -> Drop down and select Aggregate

Under Data LIF configuration

Target Allias -> iSCSI host name

Before assigning host name create host record to reserve it with static IP

LUN Size -> Assign LUN size

Assign IP Address -> Without a subnet

One page will open separately to assign IP address

Host Initiator -> Assign iSCSI initiator

For Windows server below steps to capture iSCSI initiator details

Click Configuration

Copy Initiator details from Initiator Name

Once Initiator details capture click Submit and Continue

Under SVM Administrator details

Enter Administrator Password

check mark Create a new LIF for SVM management

Assign IP Address drop down and select with subnet

Enter IP Address

Enter Netmask

Press OK

Now click Browse

Select Ethernet port -> OK

Click Submit and Continue

Click OK

To check SVM configuration

Select SVM -> Setting

Select iSCSI -> check servce status

iSCSI service

iSCSI target alias

Now login to windows server

Open iSCSI initiator

Click Target -> Enter Target name (iSCSI server IP or Name)

Click quick connect
