Attaching an ESXi 6.5 host to a Storage Center array with iSCSI using the software iSCSI initiator


In this video, I will demonstrate
attaching a VMware ESXi 6.5 host to a Storage Center array with
iSCSI using the software iSCSI initiator. To attach an iSCSI host
to a Storage Center, it is recommended to use a
Dell customized ISO for VMware. Click on the Summary tab,
then review the image profile. If you plan on using the
iSCSI software initiator, check to see if the server has
an iSCSI offload NIC in it. Click on the Configure
tab, then Storage Adapters. Locate iSCSI HBAs. In this case, we have the embedded QLogic
10 gig adapters and the PowerEdge server. We will need to disable the iSCSI driver. If you don’t have hardware iSCSI
initiators, you can skip this part. First enable SSH by clicking
on Security Profile. Scroll down to Services, click Edit. Highlight SSH and click Start, then OK. Connect to your ESXi host using
an SSH client, such as PuTTY. Log in as root. Type esxcfg-module -d bnx2i Enter maintenance mode and reboot. After the reboot exit maintenance mode. Verify the iSCSI HBA is no longer
listed in storage adapters. Click on Physical Adapters
and locate the NICs. To ensure we correctly identify which NIC,
we have disabled the ports on the switch. I will enable the port connected to fault
domain 1 and then rescan the adapter. We can see VMNIC0 came online at 10GB. We then repeat for the NIC
connected to fault domain 2. Click on VMkernel adapters,
then the Add icon. Click Next. Select New Standard Switch and then Next. Click the plus icon, locate
the VMNIC for fault domain 1, highlight it, and click OK. Click Next. Update the network label and click Next. Select Use Static IPv4 Settings. Enter the settings and click Next. Be sure the IP addresses match
the subnet for fault domain 1. Click Finish. Repeat for the other iSCSI
adapter for fault domain 2. Click on Storage Adapters. Click on the plus icon. Select software iSCSI Adapter. Click OK. Scroll down to the iSCSI Software
Adapter, highlight the VMHBA, then click on Targets. Highlight Dynamic Discovery and click Add. Enter the iSCSI target IP address
for fault domain 1 and then OK. Repeat for fault domain 2. Launch the Dell Storage Manager client. Log into the Storage Center that
the ESX host will be connecting to. On the Storage tab,
right click the servers and choose Create Server from
VMware, vSphere, or vCenter. Review the prerequisites and click Next. Provide the credentials
for the ESX host that we’ll be connecting to the Storage
Center and click Next. Both fault domains should be reachable,
if not, troubleshoot before continuing. Click Next to continue. You should receive the Host
Setup Successful screen. You can use a Copy to Clipboard
feature to save the best practices. Click on Launch Wizard to create volume
for this host, then click Finish. Update the volume name and click Next. Update the capacity and click Next. Make any modifications necessary for
the storage options and click Next. Adjust these snapshot profiles
for the volume and click Next. Click Next to map the
volume to the server. Click Finish. To view mappings, click on Mappings. If you click on Servers, in this server
you can see the connections as well. To use the newly created volume,
open the vSphere web client and click on Data Stores. Click on the plus icon. Choose VMSS and click Next. Provide a name and select
the COMPELNT iSCSI disk. Select a version and click Next. Make any adjustments and click Next. Click Finish.

One thought on “Attaching an ESXi 6.5 host to a Storage Center array with iSCSI using the software iSCSI initiator

  1. May I ask, as per VMware/SC Best Practice with multiple iscsi subnet target (same here in your video), you don't need to do vmkernel port binding, like what you demonstrated here on the video. But when I tried performing the same steps, I can see on the ESXi events/logs that during creation of ESXi host using the wizard on the Dell Storage Client, it does create port binding… and when you check the iscsi initiator software adapter, it did actually created port binding, can you please comment on this.
