Using the NIM dtls_init operation

Use the dtls_init operation to prepare resources for use by a dataless client.

The command line syntax for the dtls_init operation is as follows:
nim -o dtls_init -a Attribute=Value ... TargetName |TargetNames

The target of a dtls_init operation can be any dataless NIM client or group of dataless NIM clients.

The following are required attributes that can be specified for the dtls_init operation:
Item Description
-a dump=Value Specifies the dump resource that contains client dump files.
-a spot=Value Specifies the SPOT resource to be used to provide network boot support and the /usr file system for clients.
-a root=Value Specifies the root resource that contains the client root (/) directories. The root resource must be served by the same machine that serves the SPOT.
The following are optional attributes that can be specified for the dtls_init operation:
Item Description
-a paging=Value Specifies the paging resource containing client paging files.
-a group=Value Specifies the name of a resource group to use for the installation. A resource group can be specified as an alternative to specifying multiple resources as separate attributes.
-a home=Value Specifies the home resource that contains client /home directories.
-a resolv_conf=Value Specifies the resolv_conf resource to configure Domain Name Protocol name server information on the client.
-a shared_home=Value Specifies the shared_home resource that contains a common /home directory for multiple clients.
-a size=Value Specifies the size in megabytes for client paging files.
-a tmp=Value Specifies the tmp resource that contains client /tmp directories.
-a verbose=Value Displays information for debugging. Valid values are 1-5. Use verbose=5 to show maximum detail. The default is to show no debugging output.

The dtls_init operation populates client directories and creates client paging and dump files. A network boot image is also allocated to the client. When the client boots over the network, it obtains the boot image and is configured to mount the remaining resources.
