NAME [Toc] [Back]
info - diskless client configuration information file
DESCRIPTION [Toc] [Back]
The info file is a POSIX shell sourceable file which contains
parameter definitions used at boot time. Typically, it will be an
empty file and default values will be used for all parameters.
Following is the list of parameters which can be defined in the info
file:
ROOT_SERVER_IP Specifies the IP address of the client's
private root server. If this is not
specified, the client's private root
server defaults to the boot server.
PRIVATE_ROOT Specifies the pathname to the client's
private root on the private root server.
If this is not specified, the client's
private root path defaults to
/export/private_roots/client_name.
MOUNT_ROOT_OPTS Specifies the NFS mount options to mount
the client's private root from the
private root server. If this is not
specified, the mount options default to
boot,hard,nointr,nodevs.
MOUNT_STAND_OPTS Specifies the NFS mount options to mount
the client's /stand directory from the
boot server. If this is not specified,
the mount options default to
boot,hard,nointr,nodevs.
NO_SWAP_TO_NFS Specifies whether NFS should be
configured as primary swap. (NOTE: In
order to swap to NFS, a diskless kernel
must be configured with tunable
parameter remote_nfs_swap set to 1.) If
a diskless machine has a local swap disk
and swap to NFS is not desired, the
NO_SWAP_TO_NFS parameter should be set
to the value of 1 and the diskless
kernel should be configured without
setting remote_nfs_swap to 1. If this
parameter is not specified in the info
file and the kernel tunable parameter
remote_nfs_swap is set to 1, then NFS
will be configured as primary swap.
REMOVE_EXTRA_SWAPFILES If not set, this parameter defaults to a
value of 1, and results in the removal

of all swapfiles above the configured
swap minimum (swap min is specified in
the client's /etc/fstab) when a diskless
client boots. This ensures that
extraneous swapfiles at boot time are
removed, thus freeing disk space. If
REMOVE_EXTRA_SWAPFILES is set to 0 in
the info file, removal of extra
swapfiles is disabled. This may result
in faster boot times due to the time
savings in creating additional swap
files.
The info file resides in the same directory as the client's kernel
(/export/tftpboot/client/stand) on the boot server and is retrieved at
boot time using tftp command. By default, when a diskless client is
created, an empty info file is placed in the client's kernel
directory. This ensures that all parameters revert to their default
values (see above). If the file is not present, this is an error.
