In order for there to be an out-of-band Ethernet connection between the local management host and the array controllers, the management host and the array controllers must have valid IP addresses.
This chapter describes how to configure IP addressing on the local management host and the array controllers. It contains the following sections:
The Sun StorageTek 6140 Array is managed out-of-band by way of a standard Ethernet connection between the redundant array of independent disk (RAID) controllers and your management host.
Perform the following procedures to ensure that the local management host and the array controllers have valid IP addresses:
You can configure two types of IP addressing for Ethernet port 1 of each array controller:
By default, if the array 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 Ethernet port 1 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 array power on, this server assigns a dynamic IP address for Ethernet port 1 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 Array Controllers.
If you want to set up a DHCP server, refer to Appendix A 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 two ways:
There are two methods of assigning static IP addresses to the Ethernet ports of a controller:
|Note - It is recommended that you use the serial port interface to assign IP addresses to Ethernet port 1 of each controller, if possible.|
You can use the serial port interface on a controller to set the IP address for Ethernet port 1 on the controller.
To use the serial port interface to configure IP addressing for Ethernet port 1 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. Two 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 connector on the controller (Controller Tray Port and Components (Back View)).
2. Connect the RJ-45 connector of the serial cable to the serial port connector on the terminal.
To set up a terminal emulation program to connect to the serial port:
1. Select VT100 emulation.
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. Press Break.
|Note - The array serial port requires that the break character be received. Use the appropriate escape sequence for your terminal setup to send the required break character to the array controller, For example, you generate the Break character on some terminals by pressing the Control and Break keys simultaneously.|
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:
Baud rate set to 38400
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 Ethernet port 1 on the controller.
|Note - Ethernet port 2 is reserved for future use.|
To set up the IP address configuration for Ethernet port 1 on each controller:
1. Select option 2, Change IP Configuration:
The Select Ethernet Port menu is displayed.
2. Specify the Ethernet port for which you want to configure IP addressing:
3. 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.
4. Enter the static IP address and, optionally, a subnet mask for the Ethernet port:
|Note - If you are not using DHCP IP addressing and have previously changed the gateway IP address, you must also specify a gateway IP address for the Ethernet port.|
5. When prompted, confirm the specified IP addressing.
The Service Interface menu is redisplayed.
6. Select option 1, Display IP Configuration, to confirm the IP address changes.
The Select Ethernet Port menu is displayed.
7. Specify the Ethernet port for which you want to display IP addressing:
The IP address configuration of the selected Ethernet port is displayed, and the Service Interface menu is redisplayed.
8. Press Q to quit the Service Interface menu.
9. Repeat these steps for the second Ethernet port on the controller.
When you have completed the IP address configuration for the Ethernet ports on both array controllers, see the Sun StorageTek Common Array Manager Software Installation Guide for instructions on registering and configuring the array.
