“Driver Not Found” Discovery Error Message Misleading For Sun Fire X4100 and Sun Fire X4200 Servers (6299780)

The error message “Driver Not Found” is misleading when Sun Fire X4100 and Sun Fire X4200 servers fail discovery. The error occurs because the management server cannot create an SSH connection to the server.

Workaround: Check the SSH credentials by using ssh to access the system directly, and update the credentials accordingly.

Discovery of Sun Fire V20z and V40z Servers Will Fail if SSH Credentials are Configured but IPMI Credentials are Not (6307349)

Discovery of a Sun Fire V20z or V40z server will fail if the server's SSH credentials are configured but its IPMI credentials are not. This issue can occur as follows:

• For all SP firmware revisions, the server was previously configured with SSH credentials, but the IPMI credentials were not configured.

• For firmware revisions 2.3.0.11 and later, SSH and IPMI credentials were previously configured, but IPMI was manually disabled on the service processor using the ipmi disable channel lan command. This command unconfigures the IPMI credentials, which was not the case for previous firmware revisions.

The following error messages display when this issue occurs:

• The Discovery job:

  Errors Results Result 1: Server: 10.0.3.12 Status: -3 Message: An exception occurred trying to access 10.0.3.12. Please refer to the log file for more information.

• The syslog file:

  Aug 25 17:43:26 lab126-rh-n1sm cacao[9720]: v20z.V20zAuthService.authenticate : IPMI channel enabling failed. IPMI user account needs to be initialized.

Workaround: Enable IPMI on the Sun Fire V20z or Sun Fire V40z server using the following procedure and rerun discovery.

1. Log in to the service processor.

2. Enable IPMI:

   sp$ ipmi enable channel lan

3. Enter the password when prompted.
