Configuring the IP Address of the Array Controllers
You can configure two types of IP addressing for the Ethernet port of each array controller:
■Dynamic Host Configuration Protocol (DHCP) IP addressing – IP addresses for the Ethernet port are assigned dynamically from a DHCP server running bootstrap protocol (BOOTP) services. An IP address assigned to an Ethernet port is held only as long as needed. By default, DHCP is not enabled at initial power- on, so you must connect to it using a serial console or the Common Array Manager and the controller’s static IP address, and then enable DHCP.
■Static IP Addressing – You assign a specific IP address to the Ethernet port of each controller. Static IP addresses remain in effect until you modify or remove them or you change the method of IP addressing for the Ethernet port to DHCP.
By default, if the array controllers cannot find a DHCP server upon initial power- on, an internal IP address is assigned to Ethernet port 1 of each controller:
■The Ethernet port of Controller A is assigned IP address 192.168.128.101
■The Ethernet port of Controller B is assigned IP address 192.168.128.102
■The default subnet mask for each port is 255.255.255.0
To configure the Ethernet port on a controller with either dynamic or static IP addressing, see one of the following sections:
■“Configuring Dynamic (DHCP) IP Addressing” on page 74
■“Configuring Static IP Addressing” on page 75
Configuring Dynamic (DHCP) IP Addressing
If BOOTP services are available on the DHCP server at initial array power on, this server assigns a dynamic IP address for the Ethernet port on each controller.
If a DHCP server is not available, the controller tray defaults to internal static IP addresses as described in “Configuring the IP Address of the Array Controllers” on page 74.
If you want to set up a DHCP server, refer to Appendix A for a description of how to configure BOOTP services in Sun Solaris or Microsoft Windows environments.
You can restore DHCP IP addressing to Ethernet port 1 of either controller in either of three ways:
■Start a DHCP server on the same subnet, then reboot the 2500 Series Array.
