Perhaps a hung NFS mount ?

Hi all;
I've got an S80 running AIX 4.3.3 ML 10 that has decided it doesn't want to
finish booting.
A little background...Due to the specifics of this contract I am going
through a pretty rigerous audit trying to get this server "certified"...in
doing so I've had to make TONS of changes from last Wednesday afternoon
through Friday (when the auditors arrived). I've had to disable services,
modifiy group/owner/permissions on system files, enable system auditing,
enable syslogging, and some other stuff that I'm sure I've forgot. All the
changes I've made are documented, and I do have mksysb's up the wazooo I
can restore back to if it comes down to that. But I hope it doesn't.
Anyway, after varying on all VG's and mounting all filesystems, the last
thing I see is "Multi User Initialization Complete" (last line of /etc/rc
script)...and it just sits there. Assuming it is walking down the inittab
(and as I have no /etc/firstboot file) it appears to be hanging on the
srcmstr. Though I'm not real sure why it would be hanging here? I can
ping the box, but I can't telnet/ftp as the tcpip daemons aren't loaded.
This first happened Firday night, I finally had to reboot the box into
maint mode, remove all but the "brc", "init", and "cons" lines out of the
inittab and then the server booted just fine. I then manually executed
everything else in the inittab and I encountered NO problems. NOTHING
hung...NOTHING errored out. Also, no filesystems were full and there were
no errors to speak of in the errpt or the bootlog. I rebooted after I
verified everything was up and running and the server REBOOTED JUST FINE!
?????
On Saturday I had to disable SNMPd as well as all associated daemons dpid2
and muxatmd (not using ATM or SNMP), I also had to comment the 2 ATM lines
out of the inittab. Oh, and I had to move nfs-mountd onto a reserved port.
The server is scheduled to reboot every Monday 5AM - this morning I came in
and it was hung at the same spot. So I did a repeat of Friday night and it
worked just fine. Though I haven't rebooted a second time to see if it
would come back up.
If anyone has any insight into what might be going on I'd sure appreciate
it.
Thanks;
Theresa
