Downloading the
Internet Address
You can download the Internet address to the AXIS StorPoint CD in
four different ways, using the ARP, the RARP, the BOOTP
,
or the
DHCP method.
The main characteristics for each method are:
• ARP - available in Windows 95, Windows NT, UNIX and OS/2.
This is generally considered the easiest method although it
requires the Internet address for each new device to be
downloaded individually. Also, it is not appropriate to use this
method over routers.
• RARP- available in UNIX. Downloads the Internet address to
each device automatically. Requires a RARP daemon on your
system and operates within a single network segment only.
• BOOTP- available in UNIX. Similar to RARP, but operates on
the entire network. Requires a BOOTP daemon on your system.
• DHCP- available in UNIX and Windows NT. It allows for
automatic but temporary assignment of Internet addresses from a
central pool. In the absence of either an active RARP or BOOTP
daemon running on the host, DHCP will, when enabled, cause
the selected host to automatically allocate and download a free
Internet address, default router address and net mask to the
requesting StorPoint CD. It also provides validation data that
defines how long the Internet addresses will remain valid.
Procedures for using each of the methods are outlined below.
The RARP, the BOOTP
,
and the DHCP methods can be enabled or
disabled by setting the
RARPEnable
,
BOOTPEnable
and
DHCPEnable
parameters in the
config.ini
file. The default setting is
yes
.
Caution
0
Only one of the RARP, BOOTP and DHCP methods for setting the
Internet address should be enabled at a time. If both a BOOTP and a
DHCP server on the network provides an Internet address, then the
BOOTP address will be used. If both a RARP and a BOOTP or
DHCP server provides an Internet address at the same time, the
results will be undefined.
