Running stand-alone diagnostics from a Network Installation Management server
Learn how to run the stand-alone diagnostics from a Network Installation Manager (NIM) server.
The stand-alone diagnostics can help you perform hardware analysis. If a problem is found, you will receive a service request number (SRN) that can help pinpoint the problem and determine a corrective action.
A client system connected to a network with a NIM server
can boot stand-alone diagnostics from the NIM server if the client-specific
settings on both the NIM server and client are correctly configured.
Notes:
- For NIM clients that have adapters that would normally require that supplemental media be installed when stand-alone diagnostics are run from CD or DVD, the support code for these adapters must be installed into the directory pointed to by the NIM SPOT from which you want to boot that client. Before running stand-alone diagnostics on these clients from the NIM server, the NIM server system administrator must ensure that any needed support for these devices is installed on the server.
- All operations to configure the NIM server require root user authority.
- 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.
- The Cstate for each stand-alone diagnostics client on the NIM server should be kept in the diagnostic boot has been enabled state.
- 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 stand-alone diagnostics from the NIM server if there is a problem booting from the disk drive. See the Multiboot section under SMS in the client system's service information about setting the bootlist.
Configuring the NIM server
For
information about performing the following tasks, see the Advanced
NIM configuration tasks chapter of the AIX Installation Guide
and Reference:
- Registering a client on the NIM server
- Enabling a client to run diagnostics from the NIM server
To verify that the client system is registered on the
NIM server and the diagnostic boot is enabled, run the command from
the command line on the NIM server:
Isnim -a Cstate -z ClientName
Note: The
ClientName is the name of the system on which you want to run stand-alone
diagnostics.
Refer to the following table for system
responses.
System response | Client status |
---|---|
#name:Cstate:ClientName:diagnostic boot has been enabled: | The client system is registered on the NIM server and enabled to run diagnostics from the NIM server. |
#name:Cstate:ClientName:ready for a NIM operation:or #name:Cstate:ClientName:B0S installation has been enabled: | 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.
|
0042–053 Isnim: there is no NIM object named "ClientName" | The client is not registered on the NIM server. |
