Configuring an AMS 2100/2300
This section explains how to set up and configure an AMS 2100/2300.
Prerequisites
Before using Navigator 2, please read the following notes and instructions.
• If you are using Microsoft Windows, disable Windows power
management to prevent the PC from entering the low power mode
suspension state.
• When connecting the array with Navigator 2 via a LAN, depending on
the LAN environment, the array could be disconnected if there is a data
transfer time-out. When Navigator 2 cannot connect with the array,
verify the connection by pinging the array from the management
console. If ping command returns an IP address and does not time out,
the LAN environment may be negatively affecting the data transfer. The
length of data to be transferred can be changed with the lanconf.inf file
in the directory in which Navigator 2 is installed. The default setting is
32768. Change the setting to 16384 or 8192 in that order, or to a
multiple of 1024, and then retry. The new setting becomes effective
during the next operation (restarting Navigator 2 is not required).
Navigator 2 operations may be very slow, depending on the setting. If
the connection cannot be made after the settings are changed, review
the LAN environment.
• Do not use the reserved words discrete for each OS or device names
that indicate the input/output destinations as a file name when a file is
output. Windows includes “con”, “pm”, “ax”, etc. and UNIX® includes “/
def*”, etc. For example, when context is specified as an output file
name, an error message is displayed in a window.
• If you connect Navigator 2 to an array via a LAN, set the TCP/IP port
number to 1099. If you cannot connect, verify the TCP/IP port number.
