5 Congure the discovery method.
Option Description
Dynamic Discovery
a Click Dynamic Discovery and click Add.
b Type 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, you 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 Browse to the host in the vSphere Web Client navigator.
2 Click the Manage tab, and click Storage.
3 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 veries 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 verication is based on a predened
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 congure dierent credentials for each target
to achieve greater level of security.
Choosing CHAP Authentication Method
ESXi supports unidirectional CHAP for all types of iSCSI initiators, and bidirectional CHAP for software
and dependent hardware iSCSI.
Before conguring CHAP, check whether CHAP is enabled at the iSCSI storage system and check the CHAP
authentication method the system supports. If CHAP is enabled, enable it for your initiators, making sure
that the CHAP authentication credentials match the credentials on the iSCSI storage.
