How To Create iSCSI LUN And Discover In Windows Host Netapp Cluster Mode HD

Today we will discuss how to create iscsi LUN in SVM NetApp Cluster Mode and allocate it to a Windows Host. In previous video we discussed how to configure iSCSI in SVM Netapp Cluster Mode. Click here to know more about it. Below are the overall steps need to perform in order to create iSCSI LUN in SVM NetApp Cluster Mode and how we can allocate it to windows host. Complete Steps to Create iscsi LUN in SVM NetApp Cluster Mode. 1. Create Volume in SVM 2. Create a LUN over the volume 3. Create PortSet in SVM 4. Create a Initiator group in SVM 5. Bind the Igroup in portset 6. Map the LUN to Igroup 7. Discover the device in Windows Server We are going to discuss about each step one by one along with the command that we need to use to enable Create iscsi LUN in SVM NetApp Cluster Mode. Step 1: Create Volume in SVM Netapp Cluster Mode. Below command will create a volume in SVM NetApp Cluster Mode. This step is necessary because a LUN can reside over a volume or qtree. The volume should be thick volume as per netapp best practice recommendation. volume create -vserver vs1 -volume vol1 -aggregate aggr1 -state online -junction-path /vol1 -size 1G -space-guarantee volume Step 2. Create a LUN over the volume in SVM Netapp Cluster Mode In this step we will create a LUN over a volume. As per netapp best practice recommendation we should create a thick volume. In this command the “-space-reserve enable” makes the LUN as thick. lun create -vserver vs1 -path /vol/vol1/lun1 -size 1GB -ostype windows_2008 -space-reserve enabled If your host operating system is Windows 2012, you must use the windows_2008 ostype. Space-reserve is enabled by default. If you want a non-space-reserved LUN, you must set the space-reserve option to disabled. Step 3. Create PortSet in SVM Netapp Cluster Mode Port Set are nothing but grouping of target iSCSI lifs. It is better to use ports sets when we have multiple targets on a node and you want to restrict access of a certain target to a specific initiator. Do not confuse port set with the physical ports. Below is the command which will create a port set and add two iSCSI target lif. portset create -vserver vs1 -portset portset1 -protocol iSCSI -port-name iscsilif1 iscsilif2 You can see the port set details by executing the below command. portset show -vserver vs1 Step 4. Create an Initiator group in SVM Netapp Cluster Mode In this step we are going to create initiator group in SVM. This is also called igroup which is nothing but collection of initiator IQN number. In iSCSI lun allocation IQN are similar to WWPN in FC protocol. igroup create -vserver vs1 -igroup igroup1 -protocol iscsi -ostype windows_2008 -initiator iqn.1991-05.com.microsoft:hostA Step 5. Bind the Igroup to portset in SVM Netapp Cluster Mode In this step we will bind the igroup to the portset. Once this step is completed the the initiator will be able to communicate to the iSCSI target lif which are present in port
