iSCSI Configuration for VMware
This section provides information on the setup and configuration of the VMware
ESX Server v3.x iSCSI initiator. For more information regarding installation and
configuration of required VMware components, refer to the documentation
included with the VMware ESX Server installation.
Configuration Notes
• When you install VMware ESX Server, the software iSCSI Initiator is
automatically installed. Make sure ESX Server has a VMkernel port for iSCSI
traffic and iSCSI port in the ESX Server Firewall is enabled. For more information
about configuring your software/hardware iSCSi intiator, refer VMware iSCSI
SAN Configuration Guide.
• Upon discovering logical devices on the iSCSI Storage Appliance, the VMware
ESX initiator will find all assigned logical devices and automatically log into
them. If logical devices are distributed across multiple systems, you can use
CHAP authentication to restrict the number of logical devices the VMware
initiator can access. See “Controlling Access to Your IP SAN with
Authentication” on page 85 for more information.
• When adding a new ESX initiator to the Auto-discovery Control List, you must
have the “uses permanent discovery session” option enabled. For more
information refer “Modifying a Discovery Control List” on page 84.
