First we have to create a new LUN in System Manager (have a post for how to create an iSCSI LUN)

I will show you the steps again :

This time select VMWare for the Operating System :



Go to your VC , and select the ESX Host . From the Hardware select Storage Adapters .
We need the iSCSI name of the "iSCSI Software Adapter" : ( copy it )


And insert it in the Initiator tab in your NetAPP System Manager console :




Review the settings and click on Next to create the LUN :


The LUN has created successfully :




Now go back to your ESX Host in vCenter . Click on Storage and "Rescan All..." :


When the scan process is done , click on "Add Storage..." and select "Disk/LUN" :



Unfortunately looks like my ESX server can't see the iSCSI LUN created in my NetApp :



Let's check the "Security Profile" and "Firewall" settings of my ESX server and make sure the " Software iSCSI Client " is selected and allowed :



As you can see it's not selected :


Select it and click on OK :


Also go back and check the Sotrage Adapter Properties :


Make sure you have added the IP Address of NetApp server in Dynamic Discovery tab :


When all is done, go back to Storage and "Rescan all the Storages" again . After that click on "Add Storage..." again . This time you will see the iSCSI LUN we created in NetAPP :


Select the VMFS version as you want :


Click on Next to continue :


Select a name for the new Datastore :


And specify the capacity of new Datastore :


Ooooops , don't have enough space on the LUN :


Let's go back to NetApp System Manager and increase the size of this LUN :


Done, increased the size of LUN :



Re-scan the Storages and try to do the steps again :



Browse the new Datastore and try to create a folder in it or upload some files/folders :



*********************************************************************************
You can run this command on ESX console to make sure the Software iSCSI is enabled in Firewall and running :

esxcfg-swiscsi -q





If you need to enable it , you can run this command :

esxcfg-swiscsi -e
