I have a IBM RS/6000 7025 F50 with 4x332 MHz and 1 Gb RAM. It has AIX
5.2 installed. It has not been used for about a month, but was (as far
as I recall) shut down cleanly when last used.

Today I tried to boot it, but it won't boot fully. It goes though
various messages on the 16x2 character display, such as

OK
E0A0
Exyz (lots of different xyz's)

(then the machine bleeps, then one hears the disks spin up.) Then the
display says:

AIX IS STARTING

0746
P2/Z1

MOUNT ROOT
MOUNT /USR
MOUNt /VAR
MOUNT /TMP

0517
SYNVG ROOT VG


and there is sits with the display showing:
0517
SYNVG ROOT VG


I hooked up a serial console and get on that:


Press 0 to select this console
as the active console

(so I pressed 0)

Welcome to AIX.
boot image timestamp: 15:37 07/06
The current time and date: 15:44:38 09/28/2003
number of processors: 4 size of memory: 1024Mb
boot device: /pci@fed00000/scsi@b/sd@8:2
closing stdin and stdout...
-------------------------------------------------------------------------------

Then nothing else apperas on the serial console and nothing and the
display stays at

0517
SYNVG ROOT VG


I've looked in the service manual but can't find what this 0517 means.
Any suggestions what it going on and how to get out of it ??
