Running Standalone Diagnostics From A Network Installation Management (Nim) Server - IBM pSeries 630 6C4 Service Manual

Running Standalone Diagnostics from a Network Installation
Management (NIM) Server
A client system connected to a network with a Network Installation Management (NIM) server can boot
standalone diagnostics from the NIM server if the client-specific settings on both the NIM server and client
are correct.
Notes:
1. All operations to configure the NIM server require root user authority.
2. If you replace the network adapter in the client, the network-adapter hardware-address settings for the
client must be updated on the NIM server.
3. The Cstate for each standalone diagnostics client on the NIM server should be kept in the diagnostic
boot has been enabled state.
4. On the client system, the NIM server network adapter should be put in the bootlist after the boot disk
drive. This allows the system to boot in standalone diagnostics from the NIM server if there is a
problem booting from the disk drive. For information about setting the bootlist, see the Multiboot
section under "SMS" in the client system's service guide.
NIM Server Configuration
Refer to the "Advanced NIM Configuration Tasks" chapter of the AIX Installation Guide and Reference,
order number SC23-4389, for information on doing the following:
v Registering a client on the NIM server
v Enabling a client to run diagnostics from the NIM server
Documentation for the AIX operating system is available from the IBM Eserver pSeries Information
Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. Select AIX documentation. The
AIX Documentation CD contains the base set of publications for the operating system, including
system-management and end-user documentation.
To verify that the client system is registered on the NIM server and the diagnostic boot is enabled, run the
lsnim -a Cstate -Z ClientName command from the command line on the NIM server. Refer to the
following table for system responses.
Note: The ClientName is the name of the system on which you want to run standalone diagnostics.

Client Status
The client system is registered on the NIM server and
enabled to run diagnostics from the NIM server.
The client is registered on the NIM server but not enabled
to run diagnostics from the NIM server.
Note: If the client system is registered on the NIM server
but Cstate has not been set, no data will be returned.
The client is not registered on the NIM server.
