3 Enable or disable the adapter.
Option Description
Enable the software iSCSI adapter a Under Storage, click Storage Adapters, and click the Add icon.
b Select Software iSCSI Adapter and confirm that you want to add the
adapter.
The software iSCSI adapter (vmhba#) is enabled and appears on the list of
storage adapters. After enabling the adapter, the host assigns the default
iSCSI name to it. You can now complete the adapter configuration.
Disable the software iSCSI adapter a Under Storage, click Storage Adapters, and select the adapter (vmhba#) to
disable.
b Click the Properties tab.
c Click Disable and confirm that you want to disable the adapter.
The status indicates that the adapter is disabled.
d Reboot the host.
After the reboot, the adapter no longer appears on the list of storage
adapters. The storage devices associated with the adapter become
inaccessible. You can later activate the adapter.
Configure iSER Adapters
Configure iSER on your ESXi host, so that the iSCSI framework on the host can use the Remote Direct
Memory Access (RDMA) transport instead of TCP/IP.
When installed on the host, the RDMA-capable adapter appears in vCenter Server as a network adapter
(vmnic).
To make the adapter functional, you must enable the VMware iSER component, and then connect the
iSER adapter to the RDMA-capable vmnic. You can then configure typical properties, such as targets and
CHAP, for the iSER adapter.
The entire setup and configuration process for the iSER adapters involves several steps.
Step Description
Enable the VMware iSER Adapter Use the esxcli command to enable the VMware iSER adapter.
Modify General Properties for
iSCSI or iSER Adapters
If needed, change the default name and alias assigned to your adapter.
Configure Port Binding for iSCSI or
iSER
You must create network connections to bind the iSER engine and the RDMA-capable
network adapter. The process of configuring these connections is called port binding.
Note iSER does not support NIC teaming. When configuring port binding, use only one
RDMA adapter per vSwitch.
Configure Dynamic or Static
Discovery for iSCSI and iSER
Set up the dynamic discovery. With the dynamic discovery, each time the initiator contacts a
specified iSER storage system, it sends the SendTargets request to the system. The iSER
system responds by supplying a list of available targets to the initiator. In addition to the
dynamic discovery method, you can use the static discovery and manually enter information
for the targets.
