iSCSI Configuration for VMware
Appendix A Configuring iSCSI Initiators
173
Using CHAP Authentication to Enable Multiple Linux Systems to Share
Logical Devices on a Snap Server
Note
The instructions in this section are for users using ISNS.
You can use CHAP authentication to enable multiple Linux systems with in-box
initiators to share different logical devices on the iSCSI Storage Appliance. To do
this, you would set up different Usernames and Passwords for a DiscoveryAddress,
as described in Step 6 of “Setting up an In-box iSCSI Initiator” on page 169.
For example, on an iSCSI Storage Appliance (IP address:192.3.2.193), logical devices
can be configured for System A and System B. With CHAP enabled, set the System
A Username to
a
, and set the Password to
PasswordForA
. Then, for system B, set the
Username
b
, and set the Password to
PasswordForB
. The configuration will look like
the following:
In System A's
/etc/iscsi.conf
, enter:
DiscoveryAddress=192.3.2.193
Username=a
Password=PasswordForA
In System B's
/etc/iscsi.conf
, enter:
DiscoveryAddress=192.3.2.193
Username=b
Password=PasswordForB
System A and B can connect to their own logical devices on the same iSCSI Storage
Appliance (IP address 192.3.2.193) without the possibility of data corruption caused
by sharing the same logical device.
iSCSI Configuration for VMware
This section provides information on the setup and configuration of the VMware
ESX Server v3.0 and above 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 iSCSI Initiator is automatically
installed.
• On connecting to the logical devices on the iSCSI Storage Appliance, the VMware
initiator will find all logical devices and automatically log into them. If logical
devices are shared across multiple systems, you can use CHAP authentication to
