(1) Setting Range of the iSCSI Software and iSCSI HBA
The following describes the ranges that can be used for the iSCSI software and iSCSI
HBA settings. For notes on how to set these values, see the corresponding
documentation for your particular iSCSI software and iSCSI HBA.
 IP addresses
Use the same network address for both an HBA and a CHA port connected via a
common path.
 Other settings
• An IP-SAN can be used for multiple hosts.
• A single HBA can connect to multiple CHA ports.
When using the iSCSI software together with multiple NICs, be sure to connect each
NIC to a different IP network. Also, be sure to connect to the storage system by using
a different CHA port for each IP network. To view an example of the configuration
described above, see Figure 2-3: Configuration of an IP-SAN System When Using
iSCSI Software and an NIC.
