In this express method for configuring communications between
the management station and the storage array, you use Dynamic Host
Configuration Protocol (DHCP) to provide IP addresses. Each controller
has two storage management ports, and each management port will be
assigned an IP address.
Before
you begin
You have installed and configured a DHCP server
on the same subnet as the storage management ports.
The following
instructions refer to a storage array with two controllers (a duplex
configuration).
- If you have not already done so, connect an Ethernet cable to
the management station and to management port 1 on each controller
(A and B).
The DHCP server assigns an IP address to port 1 of each
controller.
Note: Do not use management port 2 on either controller. Port 2 is reserved
for use by Lenovo technical personnel.
Important: If
you disconnect and reconnect the Ethernet cable, or if the storage
array is power-cycled, DHCP assigns IP addresses again. This process
occurs until static IP addresses are configured. It is recommended
that your avoid disconnecting the cable or power-cycling the array.
If the storage array cannot get DHCP-assigned IP addresses within
30 seconds, the following default IP addresses are set:
- Controller A, port 1: 169.254.128.101
- Controller B, port 1: 169.254.128.102
- Subnet mask: 255.255.0.0
- Locate the MAC address label on the back of each controller, and
then provide your network administrator with the MAC address for port
1 of each controller.
Your network administrator needs the MAC
addresses to determine the IP address for each controller. You will
need the IP addresses to connect to your storage system through your
browser.
