Dell PowerVault ME4 Series Storage System Deployment Guide

Setting network port IP addresses using the CLI port and serial cable

You can manually set the static IP addresses for each controller module. Alternatively, you can specify that IP addresses should be set automatically for both controllers through communication with a Dynamic Host Configuration Protocol (DHCP) server.

1. From your network administrator, obtain an IP address, subnet mask, and gateway address for controller A and another for controller B.
2. Connect the provided 3.5mm/DB9 serial cable from a host computer with a serial port to the 3.5mm stereo plug CLI port on controller A. Alternatively, connect a generic mini-USB cable from a host computer to the USB CLI port on controller A.
   The mini-USB connector plugs into the USB CLI port as shown in the following figure:

   

3. Start a terminal emulator and configure it to use the display settings in Table 1 and the connection settings in Table 2.

   Table 1. Terminal emulator display settings

   Parameter	Value
   Terminal emulation mode	VT-100 or ANSI (for color support)
   Font	Terminal
   Translations	None
   Columns	80

   Table 2. Terminal emulator connection settings

   Parameter	Value
   Connector	COM3 (for example)1,2
   Baud rate	115,200
   Data bits	8
   Parity	None
   Stop bits	1
   Flow control	None

   ¹ Your host computer configuration determines which COM port is used for the Disk Array USB Port.

   ² Verify the appropriate COM port for use with the CLI.

4. Press Enter to display login prompt if necessary.
   The CLI displays the system version, Management Controller version, and login prompt.
5. If you are connecting to a storage system with G275 firmware that has not been deployed:
   1. Type manage at the login prompt and press Enter.
   2. Type !manage at the Password prompt and press Enter.
   If you are connecting to a storage system with G275 firmware that has been deployed:
   1. Type the username of a user with the manage role at the login prompt and press Enter.
   2. Type the password for the user at the Password prompt and press Enter.
6. If you are connecting to a storage system with G280 firmware that has not been deployed:
   1. Type setup at the login prompt and press Enter.
   2. Do not type anything at the Password prompt and press Enter.
   If you are connecting to a storage system with G280 firmware that has been deployed:
   1. Type the username of a user with the manage role at the login prompt and press Enter.
   2. Type the password for the user at the Password prompt and press Enter.
7. To use DHCP to set network port IP addresses, type the following command at the prompt:

   set network-parameters dhcp

   To use custom static IP addresses, type the following CLI command to set the values you obtained in step 1:

   NOTE:Run the command for controller module A first, and then run the command for controller module B.

   set network-parameters ip address netmask netmask gateway gateway controller a|b

   where:

   • address is the IP address of the controller module

   • netmask is the subnet mask

   • gateway is the IP address of the subnet router

   • a|b specifies the controller whose network parameters you are setting

   For example:

   set network-parameters ip 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.1 controller a
   set network-parameters ip 192.168.0.11 netmask 255.255.255.0 gateway 192.168.0.1 controller b

8. Type the following CLI command to verify the new IP addresses:
   show network-parameters

   The network parameters, including the IP address, subnet mask, and gateway address are displayed for each controller module.

9. Use the CLI ping command to verify connectivity to the gateway address.
   For example:

   ping 192.168.0.1

10. Open a command window on the host computer and type the following command to verify connectivity to controller A and controller B:
    ping controller-IP-address
    If you cannot access your storage system for at least three minutes after changing the IP address, restart the controllers using the CLI.

    NOTE:When you restart a Management Controller, communication with it is temporarily lost until it successfully restarts.

    Type the following CLI command to restart the Management Controller in both controllers:

    restart mc both

    CAUTION:When configuring an iSCSI storage system or a storage system that uses a combination of Fibre Channel and iSCSI SFPs, do not restart the Management Controller or exit the terminal emulator session until the CNC ports are configured as described Changing host port settings
11. Record the IP address for the controller modules to use when connecting to the storage system using PowerVault Manager.
12. When you are done using the CLI, close the terminal emulator.
