Managing Initialization Parameters
The following is the syntax of the command which changes the link selection of an
initialization record:
DEFINE SERVER CHASSIS SLOT [list ] LOADDUMP [record] LINK
identifier selection
The [record ] variable specifies the primary, secondary, or tertiary initialization record.
The identifier variable specifies either an Ethernet or a WAN link, and the selection
variable specifies either a midplane Ethernet segment or an external connection. The
following is an example of a command which changes the link selection in the secondary
initialization record of the processor module in slot 2:
Xyplex>> define chassis slot 2 loaddump secondary link ethernet 1
segment b
The link selections you specify must coincide with the possible connections for that
product. Chapter 3 describes the possible connections in the link map for each product. The
connections you specify in the link selection can differ from the connections in the
operational link map, however, as long as they are valid. For example, the operational
link map of a LAN bridge/router can specify that Ethernet 1 connects to Segment A, but the
primary initialization record can specify that Ethernet 1 connects to Segment B or an
external LAN.
The link selection in each initialization record is also independent of the link selections
in the other records for the same processor module. Because of this, two or more Ethernet
links can connect to the same midplane Ethernet segment in different initialization
records. For example, Ethernet 1 in the primary initialization record can connect to
Segment A, while Ethernet 2 in the secondary initialization record can also connect to
Segment A.
Enabling and Disabling Protocols
By default, a Network 9000 module obtains its software load image and parameters from a
flash memory card. If a flash card is not present, the module requests the software load
image and parameter file from the flash card of another module in the chassis, or one or
more hosts on the network. The enabled protocols determine where the module obtains the
files: XMOP indicates the flash card of another module or a Xyplex loader on the network,
MOP indicates a VAX/VMS host, and RARP, BOOTP and DTFTP indicate UNIX hosts.
Each initialization record has several loading and dumping protocols enabled by default if
the processor module attempts to obtain software and parameters from the network.
The SHOW/MONITOR SERVER STATUS display for each processor module shows the
name and location of the software load host, if the module obtained the software load image
from the network. The SHOW/LIST/MONITOR PARAMETER server display shows the
name and location of the parameters server.
