You should configure the VMkernel adapter in a order to access the ISCSI storage.This provides the dedicated virtual network interface for ISCSI traffic. Using these ISCSI LUN’s you can create a new datastore or can be added to the existing datastore for virtual guest use. I tried the above article with Vcenter 6 and I’m able to manage all points until point 13. With ISCSI Network Port Binding the VMkernel adapter does not show in the list only the Physical network adapters.

The views expressed anywhere on this site are strictly mine and not the opinions and views of my employer. Ethernet adapters (NIC) are designed to transfer packetized file level data among systems, servers and storage devices like NAS storage’s, they are not capable for transferring block level data over Internet. These Storage’s are Pooled together to make available to the network is iSCSI LUNs (Logical Unit Number). We can Install any Operating systems in those locally mounted LUNs as what we used to install in our Base systems. In Virtualization we need storage with high redundancy, stability, iSCSI provides those all in low cost.


Multiple numbers of Hard disk can be added in large storage environment, But we here using only 1 additional drive except Base installation disk.
Here we using only 2 drives, One for Base server installation, Other one for Storage (LUNs) which we going to create in PART-II of this series.
This series will be titled Preparation for the setting up Centralized Secure Storage using iSCSI through Parts 1-3 and covers the following topics. Open terminal and use yum command to search for the package name which need to get install for iscsi target. Let’s start the iSCSI Service, and check the status of Service up and running, iSCSI service named as tgtd. Let’s use tgtadm to list what targets and LUNS we currently got configured in our Server. The tgtd installed up and running, but there is no Output from the above command because we have not yet defined the LUNs in Target Server. Finally we need to add iptables rules for iSCSI if there is iptables deployed in your target Server. I'm Working as a System Administrator for last 10 year's with 4 years experience with Linux Distributions, fall in love with text based operating systems.

Normally, iSCSI Storage domain   will be used to store the virtual machines and NFS Storage domain  will be used to store the ISO images of guest operating systems. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. First, find the Port number of iscsi target using following netstat command, The target always listens on TCP port 3260.
Not everyone in world can afford the SAN cost since it requires lot hardwares like fiber channel cables, SFP  connectors, SAN switches and Storage. The above mentioned options will be useful when you find the multiple targets and multiple LUNS on the discover. But iSCSI storage can be easily setup using the existing system network with commodity hardware (X86 servers with DAS ).
