AIX Version 4 Files Reference
.info File
Purpose
Stores configuration information used by
the Network Install Manager (NIM).
Description
The .info file contains a series
of Korn shell variable assignments used by NIM. The .info file is
created by NIM for each client. During network boot, the rc.boot
program uses several of these variables to control processing.
If a client is initialized by NIM, the
.info file is copied into that client's /etc directory as the
/etc/niminfo file. The nimclient command uses the
/etc/niminfo file to communicate with the NIM master server.
Note: The following variable
groups are based upon the function of the variables that they contain. The
.info file itself is not divided into categories.
Variables used directly by the rc.boot
program
ROUTES |
Contains all the routing information the client needs in order to
access any allocated NIM resource. This information is presented as a series
of space-separated stanzas, each in the following format:
DestinationIPAddress:DestinationSubnet
:GatewayIPAddress |
SPOT |
Specifies the location of the shared product object tree (SPOT) to
be used during the boot process. This variable contains the host and pathname
of the client's SPOT in the following format:
HostName:SPOTDirectory |
RC_CONFIG |
Specifies the file name of the rc.config script to use. |
NIM_HOSTS |
Provides information used to construct an /etc/hosts file for the
client. The value is formatted as follows:
IPAddress:HostName
IPAddress:HostName ... |
Variables used by any rc.config script
ROOT |
Specifies the host and path name of the client's root directory in
the following format:
HostName:RootDirectory |
MOUNTS |
Contains a series of space-separated stanzas, each composed of a
remote directory specification and the point where it should be mounted. The
stanzas are in the following format:
HostName:RemoteDirectory:LocalDirectory |
Variables used by the nim commands
NIM_NAME |
Designates the name of the client's NIM machines
object. |
NIM_CONFIGURATION |
Specifies the client's NIM configuration machine type. |
NIM_MASTER |
Specifies the IP address of the NIM master server. |
NIM_MASTER_PORT |
Specifies the port number to use for client communications. |
NIM_REGISTRATION_PORT |
Specifies the port number to use for client registration. |
NIM_MAX_RETRIES |
Specifies the maximum number of retries for communication attempts
with the nimesis daemon. |
NIM_MAX_DELAY |
Sets the amount of time to wait between retries for communication
with the nimesis daemon. |
Variables used by BOS Install
The following variables are used by NIM
to control Base Operating System (BOS) installation operation:
NIM_BOSINST_DATA |
Specifies the RAM file system path name to the bosinst.data
file to be used. This variable has the following format:
Pathname |
NIM_BOS_IMAGE |
Specifies the RAM file system path name to the BOS image. |
NIM_CUSTOM |
Specifies the path name of the customization script to execute
after BOS installation. |
Variables used by the rc.dd_boot Script
The rc.dd script uses the
following variables to perform boot specific processing to create certain NIM
resources.
DTLS_PAGING_SIZE |
Contains the paging-space size that you specify. If you have not
set the paging space, the value is NULL and the rc.dd_boot script
defaults to a paging space twice that of the client's RAM space. |
DTLS_LOCAL_FS |
Contains a list of acronyms specifying the filesystems to be
created locally on the client. The possible values are tmp
and
home
. |
