Figure 13-9 iSCSI host port selection
Default subnet mask is 255.255.255.0 and default IP addresses for iSCSI ports are:
A3: 192.168.130.101
A4: 192.168.131.101
A5: 192.168.132.101
A6: 192.168.133.101
B3: 192.168.130.102
B4: 192.168.131.102
B5: 192.168.132.102
B6: 192.168.133.102
3. IPv4 and IPv6 are both enabled by default. If you do not need to use IPv6, un-select
Enable IPv6 check-box.
4. On the IPv4 Settings tab, click Obtain configuration automatically from DHCP server if
the host port address will be assigned dynamically through DHCP. To ensure that the host
ports always receive the same IP address, you should configure your DHCP server to use
MAC addresses as the base for the fixed IP address assignment.
Warning: Using DHCP for the target ports is generally not recommended. If you use
DHCP, you should assign DHCP reservations so that leases are maintained
consistently across restarts of the DS3500 storage subsystem. If static IP reservations
are not provided or you lose the DHCP configuration, the iSCSI Initiators can lose
connection to the DS3500 controller iSCSI ports and will not be able to reconnect to the
device.
5. Alternatively, click Specify configuration if you want to enter a static IP address, and
enter the address, subnet mask, and gateway.
6. In Advanced IPv4 Settings window (Figure 13-10 on page 328), you can enable native
VLAN support and specify a VLAN ID that will be used by the selected port, also Ethernet
priority can be set here.
