Configuring IP Addressing |
In order for there to be an out-of-band Ethernet connection between the local management host and the controller modules, the management host and the controllers must have valid IP addresses.
This chapter describes how to configure IP addressing on the local management host and on the controller modules. It contains the following sections:
The Sun StorageTek 2500 Series Array is managed out-of-band by way of a standard Ethernet connection between the controller modules and your management host.
Perform the following procedures to ensure that the local management host and the controllers have valid IP addresses:
You can configure two types of IP addressing for the Ethernet port of each controller:
By default, if the controllers cannot find a DHCP server upon initial power-on, an internal IP address is assigned to Ethernet port 1 of each controller:
To configure the Ethernet port on a controller with either dynamic or static IP addressing, see one of the following sections:
If BOOTP services are available on the DHCP server at initial power on of the storage array, 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 Controller Modules.
If you want to set up a DHCP server, refer to Appendix F 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:
There are two methods of assigning static IP addresses to the Ethernet ports of a controller:
You can use the serial port interface on a controller to set the IP address for the Ethernet port on the controller.
To use the serial port interface to configure IP addressing for the Ethernet port of each controller, you must complete the tasks described in the following sections:
You will establish a serial connection to each controller, Controller A and Controller B. One mini-DIN to RJ45 serial port cables are supplied with each controller tray.
To connect a terminal to the serial port of a controller:
1. Connect the 6-pin mini-DIN connector of the serial cable to the serial port on the controller (Controller Tray Rear-Access Components).
2. Connect the RJ-45 connector of the serial cable to the serial port on the terminal. It may be necessary to use the RJ45-DB9 adapter between the serial cable RJ-45 connector and the serial port of the terminal.
3. For PC and laptop serial connections, you will also need to use a null modem. Connect the RJ45-DB9 null modem adapter between the serial cable RJ-45 connector and the PC serial port.
| Note - If your PC does not have a serial port, you can use a USB-Serial Port adapter (separately available from third-party vendors; not included with 2500 Series Array ship kits). |
TABLE 9-1 shows the pinouts for the RJ45-DIN serial cable (Sun part number 530-3544) included with the 2500 Series Array ship kit.
To set up a terminal emulation program to connect to the serial port:
2. Remove any modem strings from the connection profile.
3. Set up the connection profile with the following communication settings:
To establish a connection with the serial port and display the Service Interface menu:
1. Send a Break. Repeat until text appears.
The serial port responds with a request to synchronize with the baud rate of the terminal:
Set baud rate: press <space> within 5 seconds
2. Press the space bar within five seconds.
The serial port confirms the established baud rate for the connection:
3. Press Break (see Note above)
The serial port responds with the following message:
Press within 5 seconds: <S> for Service Interface, <BREAK> for baud rate
4. Press S to access the Service Interface menu.
| Note - Send Break to synchronize the serial port to a different terminal port rate (see Note above). |
The serial port requests the serial port password:
Enter Password to access Service Interface (60 sec timeout):
5. Type the serial port password, kra16wen, and press Enter.
The Service Interface menu is displayed.
The serial port Service Interface menu enables you to set up the IP address configuration for the Ethernet port on the controller.
To set up the IP address configuration for the Ethernet port on each controller:
1. Select option 2, Change IP Configuration:
2. Specify that you do not want dynamic IP addressing, using a DHCP server, used for this port:
The current or default IP configuration for the selected Ethernet port is displayed.
3. Enter the static IP address and, optionally, a subnet mask for the Ethernet port:
|
Press '-' to return to the previous field; Press <ENTER> and then ^D to quit (Keep Changes) Current Configuration New Configuration IP Address if1 : 192.168.128.101 IP-address |
4. When prompted, confirm the specified IP addressing.
The Service Interface menu is redisplayed.
5. Select option 1, Display IP Configuration, to confirm the IP address changes.
The IP address configuration of the Ethernet port is displayed, and the Service Interface menu displays again.
6. Press Q to quit the Service Interface menu.
7. Switch the serial cable to the serial port on the other controller and repeat these steps to set the IP address on that controller as well.
8. Power cycle the controllers off and on again to reset them with the new IP address.
When you have completed the IP address configuration for the Ethernet port on both controllers and power cycled them, see the Sun StorageTek Common Array Manager Software Installation Guide for instructions on registering and configuring the storage array.
