Additional Information And Procedures; Logging In To The System; Booting From A Wan Boot Server - Sun Microsystems SPARC Enterprise M8000 Product Notes

Additional Information and Procedures

This section describes additional issues and limitations known at the time of this
release.

Logging In to the System

In addition to the standard default login, M3000/M4000/M5000/M8000/M9000
servers are delivered with a temporary login called admin to enable remote initial
login, through a serial port. The admin user privileges are fixed to useradm and
cannot be changed. You cannot log in as temporary admin using the standard UNIX
user name and password authentication or SSH public key authentication. The
temporary admin account has no password, and one cannot be added for it.
The temporary admin account is disabled after someone logs in as the default user,
or after someone logged in as temporary admin has successfully added the first user
with valid password and privileges.
If, before the default login is used, you cannot log in as temporary admin, you can
determine if someone else has done so by executing the showuser -l command.

Booting From a WAN Boot Server

The WAN boot installation method enables you to boot and install software over a
wide area network (WAN) by using HTTP. To support booting the M8000/M9000
servers from a WAN boot server, you must have the appropriate wanboot
executable installed and OpenBoot
hardware support.
For information about WAN boot servers, refer to the Solaris 10 Installation Guide:
Network-Based Installations for the version of Solaris 10 OS that you are using. You
can find Solaris 10 OS documentation here:
http://docs.sun.com/app/docs/prod/solaris.10
If you do not upgrade the wanboot executable, the server will panic, with messages
similar to the following:
krtld: load_exec: fail to expand cpu/$CPU
krtld: error during initial load/link phase
panic - boot: exitto64 returned from client program
