nimconfig Command

Purpose

Initializes the Network Installation Management (NIM) master package.

Syntax

To Initialize the NIM master package

nimconfig -a pif_name=Pif -a netname=Objectname [ -a master_port=PortNumber ] [ -a platform=Value ] [ -a registration_port=PortNumber ] [-a ring_speed=Speed | -a cable_type=CableType ]

To Rebuild the /etc/niminfo file:

nimconfig -r

Description

The nimconfig command initializes the NIM master package. You must initialize the package before any other NIM commands can be used. When you use the -a flag to supply the proper attributes, the nimconfig command initializes the NIM environment by performing the following tasks:

Flags

-a Assigns the following attribute=value pairs:
pif_name=Pif
Designates the primary network interface for the NIM master. This value must be a logical interface name (such as tr0 or en0) is in the available state.
master_port=PortNumber
Specifies the port number of the nimesis daemon used for NIM client communication.
platform=Value
Specifies the platform. The supported platforms are:
rs6K
Micro Channel-based, uniprocessor models for AIX 5.1 and earlier
rs6ksmp
Micro Channeled-based, symmetric multiprocessor models for AIX 5.1 and earlier
rspc
PowerPC PCI bus-based, uniprocessor models for AIX 5.1 and earlier
rspcsmp
PowerPC PCI bus-based, symmetric multiprocessor models for AIX 5.1 and earlier
netname=ObjectName
Specifies the name you want the nimconfig command to use when creating the network object to represent the network to which the master's primary interface connects.
ring_speed=Speed
Speed in Mbps. When the pif_name refers to a token ring network, this value must be given. Acceptable values are:

4

16

cable_type=CableType
Specifies the ethernet cable type. When the pif_name refers to an ethernet network, this value must be given. Acceptable values are:

bnc

dix

N/A

registration_port=PortNumber
Specifies the port number used for NIM client registration.
Note
If you do not specify port numbers on the command line, the port numbers in the /etc/services file for NIM are used. If the /etc/services file does not contain entries for the NIM ports nim and nimreg, the default values of 1058 for master_port and 1059 for registration_port are used.
-r Rebuilds the /etc/niminfo file on the master using the information already exists in the NIM database. Note that if the bos.sysmgt.nim.master package has not been configured on this machine, this option will fail. This option is provided in case the /etc/niminfo file is accidentally removed by a user.

Security

Access Control: You must have root authority to run the nimconfig command.

Examples

  1. To initialize the NIM environment using token ring and the default NIM ports for network communications, type:

    nimconfig -a pif_name=tr0 -a netname=net1 -a ring_speed=16
  2. To initialize the NIM environment using ethernet and the default NIM ports, type:

    nimconfig -a pif_name=en0 -a master_port=1058 \
    -a netname = net2 -a cable_type=bnc
  3. To rebuild the /etc/niminfo file on the NIM master when that machine has already been correctly configured as a master, type:

    nimconfig -r
  4. To initialize the NIM master using an ATM network interface, type:

    nimconfig -a pif_name=at0 -a master_port=1058 -a netname=ATMnet
    Note
    Because an interface to an ATM network does not currently support booting over the network, this operation will define a generic network object corresponding to the master's subnet.
  5. To initialize the NIM environment using TCP/IP port 1060 for NIM client communications and TCP/IP port 1061 for NIM client registration, type:

    nimconfig -a pif_name=tr0 -a netname=net2 -a master_port=1060 \
    -a registration_port=1061 -a ring_speed=16
