If there's no LCD error code, then the system didn't get very far. You'll need to boot from external media.

IBM - Booting in Service Mode

It's possible that the system is downlevel on firmware, and is not compatible with that AIX release/level. You may need to update the FW to proceed (although that usually involves having a bootable disk: catch-22!)

The message "AIX is starting" is issued if a hd5 with a AIX boot image is found on the bootable media. This message should get replaced with "Starting Kernel" once the kernel code has been read into memory. Sometimes this can be corrected with:

# bosboot -ad /dev/hdiskx

once the system is booted from external media and the rootvg imported and mounted.

BOOTPARAMD(8)						    BSD System Manager's Manual 					     BOOTPARAMD(8)

NAME
bootparamd -- boot parameter server SYNOPSIS
bootparamd [-ds] [-r router] [-f file] DESCRIPTION
The bootparamd utility is a server process that provides information to diskless(8) clients necessary for booting. It consults the /etc/bootparams file. This version will allow the use of aliases on the hostname in the /etc/bootparams file. The returned hostname to the whoami request done by the booting client will be the name that appears in /etc/bootparams and not the canonical name. In this way you can keep the answer short enough so that machines that cannot handle long hostnames will not fail during boot. OPTIONS
-d Display the debugging information. -s Log the debugging information with syslog(3). -r router The default router (a machine or an IP-address). This defaults to the machine running the server. -f file The file to use as boot parameter file instead of /etc/bootparams. FILES
/etc/bootparams default boot parameter file EXAMPLES
When netbooting diskless SunOS/Xkernel SPARCstations the booted SunOS kernel also broadcasts to the all-0 address. The SunOS kernel hangs until it receives a reply. To accommodate this behaviour add an alias address that responds to an all-0 broadcast. So, add something like 'ifconfig xl0 192.168.200.254 netmask 255.255.255.255 broadcast 192.168.200.0 alias' on the relevant network interface on your bootparamd server. The alias address must of course be free for use. SEE ALSO
