14 Chapter 2 HDLM Functions
Table 2.2 HDLM System Components that use IP-SAN
Components Description
iSCSI software The driver software that has the iSCSI initiator function.
iSCSI HBA A host bus adapter that has the iSCSI initiator function.
This serves as a cable port on the host. The iSCSI HBA is referred to as the HBA in HDLM commands
and HDLM GUI. It is sometimes called an HBA in this manual.
NIC A network interface card that serves as a cable port on a host. The NIC is referred to as the HBA in
HDLM commands, and HDLM GUI. It is sometimes called an HBA in this manual.
IP-SAN A data transfer network that connects hosts and storage systems by using the iSCSI standard.
CHA A channel adapter used for iSCSI connections.
P A port on a channel adapter. This serves as a cable port on a storage system.
LU A logical unit with which the host can perform input or output operations. This unit can be accessed from
the network.
Dev A logical area (a partition) in an LU.
Path A route that connects a host and a Dev in an LU.
2.2.2.1 Setting the Range of iSCSI Software and iSCSI HBA
The following describes the range of settings for the iSCSI software and iSCSI HBA. For notes
on setting the values, see the hardware notes supplied with HDLM.
 IP addresses
Set the same network address for an HBA and a CHA port connected via a path.
 Other settings
– You can share the IP-SAN with other hosts.
– A single HBA can connect to multiple CHA ports.
When using the iSCSI software and multiple NICs, connect to the storage system by each NIC
using a separate different IP network and different CHA ports for each NIC with the storage
system. To view a configuration example, see
Figure 2.3.
