I attached all the answers I received.
The solution of Stephen P Richardson certainly works,
becouse it fixed my problem. In few words, the "killproc
automoun" command, following "umountall -F autofs" in
the /etc/init.d/autofs script, kills the automount daemon,
while some autofs haven't already been umounted, and this
is why the system shutdown could't go any further.
Commenting out "killproc automount" fixes the problem,
becouse automountd is killed smoothly later on by "killall"
in the /etc/rc0 script
Before I tried also the suggestion of Ray Trzaska (replace
"umountall" with "umountall -s" in /etc/rc0), but it didn't
work.
Some guys suggested to use "init 0" instead of shutdown,
but even if it works I really wanted to understand what
was going on.

I have seen this on a 2000 with a large number of stripes on ssa arrays.
it has also cropped up in other cases with striped disks.
the 'fix', for me, was to edit /etc/rc0 to change the umount from parallel
to a sequential umount.
change in the last few lines from:
---------------------------------
# unmount file systems. /usr, /var and /var/adm are not unmounted by umountall
# because they are mounted by rcS (for single user mode) rather than
# mountall.
# If this is changed, mountall, umountall and rcS should also change.
/sbin/umountall
/sbin/umount /var/adm >/dev/null 2>&1
/sbin/umount /var >/dev/null 2>&1
/sbin/umount /usr >/dev/null 2>&1
echo 'The system is down.'

Yes, there is a solution:
comment out the line:
killproc automoun
in /etc/init.d/autofs (which is also linked to
/etc/rc2.d/S74autofs /etc/rc0.d/K69autofs
/etc/rc1.d/K68autofs.) The automounter will be gracefully
shutdown by killall later in the shutdown process, meanwhile
commenting it out of this script allows umountall to finish
before the automounter process is terminated. If your machine
is still coming down too fast, you can try adding a short
sleep call right after the umountall in autofs. I have done
this on many machines without any problem.

Hi,
Is this problem related to the position of the S1000 key switch, I can't test at the moment as the systems are live, though I seem to remember that if the key is in the position so that STOP-A can't be used, using shutdown behaves the way you described. Trying moving the position of the key switch and trying again.
Hope that helps

There is an lofs bug filled out with sun and they have a patch for it. I had the same probelms with 1000's and 2000's. I had to beat up on sun to get a ptch release.
Basically, if you look at the umountall script, it unmounts nfs, ufs and lofs (autofs) filesystems. If you hve loopback file systems (lofs) through the automounter, and the actual file systems reside on the local machine, then you see this problem. The machine will EVENTUALLY come down, but the time is directly exponentially related to the # of lofs you have.
Sorry that I do not have the bug id, or the patch id, but there is a lofs and automount path on sunsolve1.sun.com. That should help you out.
Hope this helps . . .

I tend to use init to change runlevels, init 0 works fine on my 2.5 ss5's which use autofs. I have heard from several sun sources (engineers & course instructors) that init is the preferred way to do this.

Hi List,
does anybody have any idea why my Sparc1000 (Solaris 2.5) cannot arrive to the 'ok' prompt when a 'shutdown -g0 -i0 -y' is issued? It arrives very close to the end, then it says that /home is busy, /opt is busy, then 'System is down.', but the prompt is not reached.
Thanks in advance. I'll summarize.

I received only an answer by Ray Trzaska, pointing me to the command "umountall" in the /etc/rc0 script, and suggesting me to replace it with "umountall -s". Well, it didn't work but the problem must be somehow related to conflicts between that command and the fact that automounted filesystems are still mounted and the automountd daemon is already died, so they cannot be umounted. There is also a specific bug in the SunSolve CD about that (but no workarounds)
Now, I finally asked support to Sun, and the Sun engineer who picked up the call told me that there is nothing I can do, that's the way Solaris2.5 works, use allways /etc/halt or reboot, and then closed the call! It seems to me very strange that is impossible to use the "shutdown" command when autofs is used.
If anybody of you have a suggestion, it will be very appreciated.

Use 'init 0' That is the cleanest way to shutdown solaris. That runlevel stops all the processes 'nicely' , closes files, syncs filesystem, stops daemons etc. Halt or fasthalt merely does a killall ! Shutdown should do roughly the same as init 0, but it obviously getting upset about somethig ....
