Chapter 4 – Configuring the RAM-SAN

This chapter focuses on configuring the RAM-SAN. This includes configuring the Ethernet parameters, resizing LUNS, and performing LUN Masking.

4.1 The RAM-SAN Monitor

The RAM-SAN is managed through an interactive command tool. The management software is accessed over Ethernet or the serial port on the RAM-SAN. See section 2.4 for more information on connecting the hardware.

4.2 Configuring the Ethernet Port

The Ethernet port may be configured using automatic IP address assigned via bootp or rarp. Consult with your system administrator for the proper procedure in this type of network configuration.

The following procedure may be used to statically set the IP from the serial port:

1.Using the serial cable provided connect the management port to a serial port on a computer or dumb terminal. The serial settings should be 9600 baud, 8 data bits, no parity, and 1 stop bit.

2.Make sure the power cable is connected to the RAM-SAN and turn it on.

3.You should see messages on the console that show the power-on stages.

4.Once you see the ‘ram-san>’ prompt, enter the ‘ipconfig’ command. If you are using an automated IP assignment such as reverse address resolution protocol (rarp) then select 2. Otherwise the static IP selection will prompt you for your IP, subnet mask, and gateway. Pressing return without any input will automatically pick the default value. The output from the ‘ipconfig’ command looks like this:

ram-san> ipconfig

1.Static IP

2.Rarp or Bootp

Select: 1

Ethernet IP address [255.255.255.255]: 192.94.231.201

Ethernet subnet mak [255.255.255.0]: <enter>

Ethernet gateway [255.255.255.255]: <enter> ram-san>

5.NOTE: Type ‘reboot soft’ to reboot the RAM-SAN in order for the changes to take effect.

4.3Configuring LUNS

The RAM-SAN is extremely versatile because it supports a variety of configurations and access control methods. The factory default configuration assumes no LUN masking and equal LUN sizes for each Fibre Channel port. For example, if you have an 8 GB system with 2 Fibre Channel ports, each port will only have access to one 4 GB LUN. Any host computer attached to the same Fabric as the RAM-SAN will see two 4 GB drives.
