Table 11-1 shows the IP configuration settings for each iSCSI port on both canisters. As
described earlier, they are attached to Ethernet switches in the IBM Flex System Enterprise
Chassis I/O Module ports 1 and 2.

The host is detailed in 6.2.2, “Creating an iSCSI attached host” on page 276 where the IQN of
the x240 compute node is defined. The IQN number is taken from the host as provided by the
operating system. See Figure 11-7 for the setup.

The IQN for each IBM Flex System V7000 Storage Node canister is as follows:
򐂰 iqn.1986-03.com.ibm:2145.flexsystemv7000.node1
򐂰 iqn.1986-03.com.ibm:2145.flexsystemv7000.node2
They are used by the host to connect to IBM Flex System V7000 Storage Node.
When the canister ports are configured as shown in Table 11-1, the link should be tested by
the host. We used a “ping” to check connectivity across the switch.
The switching involved for iSCSI is at the TCP/IP network level where multiple paths are
planned to eliminate a single point of failure in the network and for load balancing. It is also
determined by the iSCSI device driver of the host. Planning for connectivity between iSCSI
source and target devices would be at the TCP/IP network. The node canister ports are
assigned IP addresses and TCP/IP connectivity to them is tested from each host.
The full configuration process for iSCSI attachment to a WIN8 host is detailed in 12.3.2,
“Windows 2008 R2 iSCSI volume attachment” on page 520.
