3. Click Next to continue. Step 7: Configuring host ports In order for hosts to properly access the system, you must configure the system's host-interface options. For FC ports you can set these options: • Speed can be set to auto, which auto-negotiates the proper link speed with the host, or to 2Gb (Gbit per second) or 4Gb. A speed mismatch with a host prevents that host from accessing the storage system. • Connection mode can be set to loop or point-to-point. Loop protocol can be used in a physical loop or in a direct physical connection between two devices. Point-to-point protocol can only be used on a direct physical connection between exactly two devices. • Loop IDs can be set, per controller, to use soft or hard target addressing: • Soft target addressing (the default) enables a LIP to determine the loop ID. Use this setting if the loop ID is permitted to change after a LIP or power cycle. • Hard target addressing requests a specific loop ID that should remain after a LIP or power cycle. If the port cannot acquire the specified ID, it is assigned a soft target address. Use this option if you want ports to have specific addresses, if your system checks addresses in reverse order (lowest address first), or if an application requires that specific IDs be assigned to recognize the controller. For iSCSI ports you can set these options: • IP Address. The port IP address in IPv4 format. • Netmask. The port netmask address in IPv4 format. • Gateway. The port gateway address in IPv4 format. • Authentication (CHAP). Enables or disables use of Challenge Handshake Authentication Protocol. Disabled by default. • Jumbo Frames. Enables or disables support for jumbo frames. A normal frame can contain 1500 bytes whereas a jumbo frame can contain a maximum of 9000 bytes for larger data transfers. Disabled by default. NOTE: Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network components in the data path. • Link Speed. Sets the link speed to auto, which allows the system to negotiate the proper speed, or forces it to 1 Gbit/sec (1g). The default is auto. • iSNS. Enables or disables registration with a specified Internet Storage Name Service server, which provides name-to-IP-address mapping. Disabled by default. • iSNS Address. Specifies the IP address of an iSNS server. The default address is all zeroes. • Alternate iSNS Address. Specifies the IP address of an alternate iSNS server, which can be on a different subnet. The default address is all zeroes. For SAS ports there are no host-interface options. Click Next to continue. To change FC host-interface settings 1. For controller host ports that are attached to hosts: • Set the speed to the proper value to communicate with the host. • Set the connection mode to loop or point-to-point. 2. For each controller, set the loop ID to use soft or hard target addressing. To use soft target addressing, select Soft?. To use hard target addressing, clear Soft? and enter an address in the range 0-125. You cannot set the same hard target address for both controllers. An asterisk indicates that the value shown will be changed. 3. Click Next to continue. HP StorageWorks 2000 G2 Modular Smart Array Reference Guide 31

Step 7: Configuring host ports
In order for hosts to properly access the system, you must configure the system's host-interface options.
For FC ports you can set these options:
•
Speed can be set to auto, which auto-negotiates the proper link speed with the host, or to 2Gb (Gbit
per second) or 4Gb. A speed mismatch with a host prevents that host from accessing the storage
system.
•
Connection mode can be set to loop or point-to-point. Loop protocol can be used in a physical loop or
in a direct physical connection between two devices. Point-to-point protocol can only be used on a
direct physical connection between exactly two devices.
•
Loop IDs can be set, per controller, to use soft or hard target addressing:
•
Soft target addressing (the default) enables a LIP to determine the loop ID. Use this setting if the loop
ID is permitted to change after a LIP or power cycle.
•
Hard target addressing requests a specific loop ID that should remain after a LIP or power cycle. If
the port cannot acquire the specified ID, it is assigned a soft target address. Use this option if you
want ports to have specific addresses, if your system checks addresses in reverse order (lowest
address first), or if an application requires that specific IDs be assigned to recognize the controller.
For iSCSI ports you can set these options:
•
IP Address. The port IP address in IPv4 format.
•
Netmask. The port netmask address in IPv4 format.
•
Gateway. The port gateway address in IPv4 format.
•
Authentication (CHAP). Enables or disables use of Challenge Handshake Authentication Protocol.
Disabled by default.
•
Jumbo Frames. Enables or disables support for jumbo frames. A normal frame can contain 1500 bytes
whereas a jumbo frame can contain a maximum of 9000 bytes for larger data transfers. Disabled by
default.
NOTE:
Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network
components in the data path.
•
Link Speed. Sets the link speed to auto, which allows the system to negotiate the proper speed, or
forces it to 1 Gbit/sec (1g). The default is auto.
•
iSNS. Enables or disables registration with a specified Internet Storage Name Service server, which
provides name-to-IP-address mapping. Disabled by default.
•
iSNS Address. Specifies the IP address of an iSNS server. The default address is all zeroes.
•
Alternate iSNS Address. Specifies the IP address of an alternate iSNS server, which can be on a
different subnet. The default address is all zeroes.
For SAS ports there are no host-interface options. Click

To change FC host-interface settings
1.
For controller host ports that are attached to hosts:
•
Set the speed to the proper value to communicate with the host.
•
Set the connection mode to loop or point-to-point.
2.
For each controller, set the loop ID to use soft or hard target addressing. To use soft target addressing,
select
Soft?
. To use hard target addressing, clear
Soft?
and enter an address in the range 0–125. You
cannot set the same hard target address for both controllers. An asterisk indicates that the value shown
will be changed.
