Configuring Discovery Addresses for iSCSI Adapters
You need to set up target discovery addresses, so that the iSCSI adapter can determine which storage
resource on the network is available for access.
The ESXi system supports these discovery methods:
Dynamic Discovery
Also known as SendTargets discovery. Each time the initiator contacts a
specied iSCSI server, the initiator sends the SendTargets request to the
server. The server responds by supplying a list of available targets to the
initiator. The names and IP addresses of these targets appear on the Static
Discovery tab. If you remove a static target added by dynamic discovery, the
target might be returned to the list the next time a rescan happens, the iSCSI
adapter is reset, or the host is rebooted.
N With software and dependent hardware iSCSI, ESXi lters target
addresses based on the IP family of the iSCSI server address specied. If the
address is IPv4, IPv6 addresses that might come in the SendTargets response
from the iSCSI server are ltered out. When DNS names are used to specify
an iSCSI server, or when the SendTargets response from the iSCSI server has
DNS names, ESXi relies on the IP family of the rst resolved entry from DNS
lookup.
Static Discovery
In addition to the dynamic discovery method, you can use static discovery
and manually enter information for the targets. The iSCSI adapter uses a list
of targets that you provide to contact and communicate with the iSCSI
servers.
Set Up Dynamic or Static Discovery for iSCSI
With dynamic discovery, each time the initiator contacts a specied iSCSI storage system, it sends the
SendTargets request to the system. The iSCSI system responds by supplying a list of available targets to the
initiator. In addition to the dynamic discovery method, you can use static discovery and manually enter
information for the targets.
When you set up static or dynamic discovery, you can only add new iSCSI targets. You cannot change any
parameters of an existing target. To make changes, remove the existing target and add a new one.
