• Loop IDs can be set, per controller, to use soft or hard target addressing:
• Soft target addressing, which is the default, enables a LIP (loop initialization process) 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.
• Netmask. The port netmask address.
• Gateway. The port gateway address.
• 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:
components in the data path.
• Link Speed.
• Auto: Auto-negotiates the proper speed. This is the default.
• 1 Gbit/s: Forces the speed to 1 Gbit/sec, overriding a downshift that can occur during
auto-negotiation with 1-Gbit/sec HBAs. This setting does not apply to 10-Gbit/sec HBAs.
• iSCSI IP Version. Specifies whether IP values use Internet Protocol version 4 (IPv4) or version 6 (IPv6)
format. IPv4 uses 32-bit addresses. IPv6 uses 128-bit addresses.
• 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.
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.
To change iSCSI host-interface settings
1. For each iSCSI port, set the IP address, netmask, and gateway. Ensure that each iSCSI host port in the
storage system is assigned a different IP address.
2. For all iSCSI ports, set the authentication, jumbo frames, link speed, and iSNS options.
3. Click Next to continue.
40 Configuring the system
Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network
