Prerequisites
Required privilege: Host.Configuration.Storage Partition Configuration
Procedure
1 Browse to the host in the vSphere Web Client navigator.
2 Click the Configure tab.
3 Under Storage, click Storage Adapters, and select the adapter (vmhba#) to configure.
4 Under Adapter Details, click the Targets tab.
5 Configure the discovery method.
Discovery Method Description
Dynamic Discovery a Click Dynamic Discovery and click Add.
b Enter the IP address or DNS name of the storage system and click OK.
c Rescan the iSCSI adapter.
After establishing the SendTargets session with the iSCSI system, your host
populates the Static Discovery list with all newly discovered targets.
Static Discovery a Click Static Discovery and click Add.
b Enter the target’s information and click OK
c Rescan the iSCSI adapter.
About Dependent Hardware iSCSI Adapters
A dependent hardware iSCSI adapter is a third-party adapter that depends on VMware networking, and
iSCSI configuration and management interfaces provided by VMware.
An example of a dependent iSCSI adapter is a Broadcom 5709 NIC. When installed on a host, it presents
its two components, a standard network adapter and an iSCSI engine, to the same port. The iSCSI
engine appears on the list of storage adapters as an iSCSI adapter (vmhba).
The iSCSI adapter is enabled by default. To make it functional, you must connect it, through a virtual
VMkernel adapter (vmk), to a physical network adapter (vmnic) associated with it. You can then configure
the iSCSI adapter.
After you configure the dependent hardware iSCSI adapter, the discovery and authentication data is
passed through the network connection. The iSCSI traffic goes through the iSCSI engine, bypassing the
network.
Dependent Hardware iSCSI Considerations
When you use dependent hardware iSCSI adapters with ESXi, certain considerations apply.
n
When you use any dependent hardware iSCSI adapter, performance reporting for a NIC associated
with the adapter might show little or no activity, even when iSCSI traffic is heavy. This behavior occurs
because the iSCSI traffic bypasses the regular networking stack.
