Running Standalone Diagnostics from a Network Installation
Management (NIM) Server
A client system connected to a network with a network installation management (NIM) server is capable of
booting standalone diagnostics from the NIM server if the client system is registered on the NIM server
and the NIM boot settings on both the server and client are correct.
Notes:
1. All operations to configure the NIM server require root access.
2. If you replace the network adapter in the client, the network adapter hardware address for the client
must be updated on the NIM server.
3. The Control State (Cstate) for standalone clients on the NIM server should be kept in the diagnostic
boot has been enabled state.
4. On the client partition, the NIM server network adapter can be put in the bootlist after the boot hardfile.
This allows the system to boot in standalone diagnostics from the NIM server, if there is a problem
booting from the hardfile. Another option is to use the Select Boot Options function in the SMS menu
to set up the network adapter that is connected to the NIM server for a one-time boot of standalone
diagnostics.
NIM Server Configuration
Refer to the "Advanced NIM Configuration Tasks" chapter of the AIX Installation Guide and Reference for
information about the following tasks::
v Register a client on the NIM server
v Enable a client to run diagnostics from the NIM server
To verify that the client system is registered on the NIM server and diagnostic boot is enabled, do the
following:
1. Run the command lsnim -a Cstate -Z ClientName from the command line on the NIM server.
Note: The ClientName is the name of the system you want to run standalone diagnostics on.
2. Refer to the following table for system responses.
System Response
#name:Cstate:
ClientName: diagnostic boot has been
enabled:
#name:Cstate:
ClientName:ready for a NIM operation:
or
