NetApp ONTAP root volume is low on space

 CRITICAL: This node is not healthy because the root volume is low on space

(<10MB). The node can still serve data, but it cannot participate in cluster

operations until this situation is rectified. Free space using the nodeshell or

contact technical support for assistance.

To fix root volume low space error on NetApp ONTAP you can delete created Snapshot on root volume using below command

cluster> node run local

node> snap delete -a vol0

node> vol options vol0 nosnap on

node> ctrl+D

cluster> reboot

Enter below command to delete Snapshot-:

snap delete -a vol0

Type Yes to confirm for deleting Snapshot.

Enter below command to set no Snapshot on Volume -:

vol options vol0 nosnap on

Press CTRL+D

Type reboot and press enter to reboot the NetApp ONTAP

Once NetApp ONTAP  will come up post reboot login with Admin and check the status.

Error message should disappear from console.

NetApp ONTAP Data LIF Create

NetApp ONTAP Data LIF -:

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

Login to NetApp ONTAP using cluster IP.

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
