Administrator Guide

• Gateway: For IPv4, gateway IP address for assigned port IP address.
• Default Router: For IPv6, default router for assigned port IP address.
3. In the Advanced Settings section of the panel, set the options that apply to all iSCSI ports:
• Enable Authentication (CHAP): Enables or disables the use of the Challenge Handshake Authentication Protocol (CHAP).
Enabling or disabling CHAP in this panel updates its setting in the Configure CHAP panel (available in the Hosts topic by selecting
Action > Configure CHAP. CHAP is disabled by default.
NOTE: CHAP records for iSCSI login authentication must be defined if CHAP is enabled. To create CHAP records,
see Configuring CHAP.
• Link Speed:
○ Auto – Auto-negotiates the proper speed.
○ 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.
• Enable Jumbo Frames: Enables or disables support for jumbo frames. Allowing for 100 bytes of overhead, a normal frame can
contain a 1400-byte payload whereas a jumbo frame can contain a maximum 8900-byte payload for larger data transfers.
NOTE: Use of jumbo frames can succeed only if jumbo-frame support is enabled on all network components in the
data path.
• 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.
• Enable iSNS: Enables or disables registration with a specified Internet Storage Name Service server, which provides name-to-IP-
address mapping.
• iSNS Address: Specifies the IP address of an iSNS server.
• Alternate iSNS Address: Specifies the IP address of an alternate iSNS server, which can be on a different subnet.
CAUTION: Changing IP settings can cause data hosts to lose access to the storage system.

Configure two ports as FC and two ports as iSCSI per controller
Perform the following steps to configure two ports as FC and two ports as iSCSI:
1. Perform one of the following to access the options in the Ports tab:
• In the Home topic, select Action > System Settings, then click the Ports tab.
• In the System topic, select Action > System Settings, then click the Ports tab.
2. From the Host Post Mode drop-down menu, select FC-and-iSCSI.
NOTE: Ports 0 and 1 are FC ports. Ports 2 and 3 are iSCSI ports.
3. Click Apply and Close.
A confirmation panel appears.
4. Click OK.
The controller modules restart.
5. Perform one of the following to access the options in the Ports tab:
• In the Home topic, select Action > System Settings, then click the Ports tab.
• In the System topic, select Action > System Settings, then click the Ports tab.
6. In the Ports Settings tab, set the FC port-specific options:
• Set the Speed option to the proper value to communicate with the host, or to auto, which auto-negotiates the proper link speed.
Because a speed mismatch prevents communication between the port and host, set a speed only if you need to force the port to
use a known speed.
• Set the Connection Mode to either point-to-point or auto:
○ point-to-point: Fibre Channel point-to-point.
○ auto: Automatically sets the mode based on the detected connection type.
7. Set the parameters for the iSCSI ports:
