Setting network port ip addresses using dhcp – HP MSA 2040 SAN Storage User Manual

Connecting to the controller CLI port
1.
Locate the DVD included with your MSA 2040 storage device.
2.
Insert the DVD into the drive on a Linux or Windows computer on the network that is connected to your
controller enclosure.
3.
Use Autorun or manually start the DVD.
The MSA Device Discovery Tool will run.
4.
Follow the instructions to discover the IP addresses of the controller or controllers.
Record these IP addresses so that you can specify them whenever you manage the controllers using the
SMU or the command-line interface.
Alternatively, you can set network port IP addresses using the command-line interface on HP-UX, Windows,
and Linux platforms.
Setting network port IP addresses using DHCP
1.
Look in the DHCP server’s pool of leased addresses for two IP addresses assigned to “HP MSA
Storage.”
2.
Use a ping broadcast to try to identify the device through the ARP table of the host.
If you do not have a DHCP server, you will need to ask your system administrator to allocate two IP
addresses, and set them using the command-line interface during initial configuration (described
below).
Setting network port IP addresses using the CLI port and cable
If you did not use the MSA Device Discovery Tool to set network port IP values, set them manually using the
command-line interface port and cable. If you have not done so already, you need to enable your system
for using the command-line interface port [also see

Windows systems see
"Downloading a device driver for Windows computers" (page 43)
.
Network ports on controller module A and controller module B are configured with the following
factory-default IP settings:
•
Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)
•
IP Subnet Mask: 255.255.255.0
•
Gateway IP Address: 10.0.0.1
If the default IP addresses are not compatible with your network, you must set an IP address for each
network port using the command-line interface embedded in each controller module. The command-line
interface enables you to access the system using the USB (universal serial bus) communication interface
and terminal emulation software. The USB cable and CLI port support USB version 2.0.
Use the CLI commands described in the steps below to set the IP address for the network port on each
controller module. Once new IP addresses are set, you can change them as needed using the SMU. Be
sure to change the IP address via the SMU before changing the network configuration.
NOTE:
Changing IP settings can cause management hosts to lose access to the storage system.
1.
From your network administrator, obtain an IP address, subnet mask, and gateway address for
controller A, and another for controller B.
Record these IP addresses so that you can specify them whenever you manage the controllers using the
SMU or the CLI.
2.
Use the provided USB cable to connect controller A to a USB port on a host computer. The USB mini 5
male connector plugs into the CLI port as shown in
(generic controller module is shown).
