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.
Remove Dynamic or Static iSCSI Targets
Remove iSCSI servers that appear on the list of targets.
Procedure
1 Navigate to the host.
2 Click the Configure tab.
3 Under Storage, click Storage Adapters, and select the iSCSI adapter to modify from the list.
4 Under Adapter Details, click the Targets tab.
5 Switch between Dynamic Discovery and Static Discovery.
6 Select an iSCSI server to remove and click Remove.
7 Rescan the iSCSI adapter.
If you are removing the static target that was dynamically discovered, you need to remove it from the
storage system before performing the rescan. Otherwise, your host will automatically discover and
add the target to the list of static targets when you rescan the adapter.
Configuring CHAP Parameters for iSCSI Adapters
Because the IP networks that the iSCSI technology uses to connect to remote targets do not protect the
data they transport, you must ensure security of the connection. One of the protocols that iSCSI
implements is the Challenge Handshake Authentication Protocol (CHAP), which verifies the legitimacy of
initiators that access targets on the network.
CHAP uses a three-way handshake algorithm to verify the identity of your host and, if applicable, of the
iSCSI target when the host and target establish a connection. The verification is based on a predefined
private value, or CHAP secret, that the initiator and target share.
ESXi supports CHAP authentication at the adapter level. In this case, all targets receive the same CHAP
name and secret from the iSCSI initiator. For software and dependent hardware iSCSI adapters, ESXi
also supports per-target CHAP authentication, which allows you to configure different credentials for each
target to achieve greater level of security.
