- Glossary of terms
● 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 or modifying unused ports may cause hosts to lose access to the storage
system.
4. Perform one of the following:
● To save your settings and continue configuring your system, click Apply.
● To save your settings and close the panel, click Apply and Close.
A confirmation panel appears.
5. Click OK.
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:
● IP Address: For IPv4 or IPv6, the port IP address. For corresponding ports in each controller, assign one port to one
subnet and the other port to a second subnet. Ensure that each iSCSI host port in the storage system is assigned a
different IP address. For example, in a system using IPv4:
○ Controller A port 2: 10.10.10.100
○ Controller A port 3: 10.11.10.120
○ Controller B port 2: 10.10.10.110
○ Controller B port 3: 10.11.10.130
● Netmask: For IPv4, subnet mask for assigned port IP address.
● Gateway: For IPv4, gateway IP address for assigned port IP address.
● Default Router: For IPv6, default router for assigned port IP address.
8. In the Advanced Settings tab of the panel, set the options that apply to all iSCSI ports:
