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.
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.
