re: filesystem boot problems after a power cycle

I had a power outage which knocked out a solaris box.
Did fsck and fixed errors.
I can boot in single user mode and have access to file
systems.
But when boot in multi user mode - it gets stuck and hangs.

If you make system down must be
with
/etc/shutdown -y -i5 -g0
y is for yes in the fsck
look man shutdown

only shutdown make work from /etc/rc0.d
 all script with K*

shutdown -y option means answer you to confirmation as to whether you realy want to shutdown, it's got nothing to do with fsck.

More importantly, where does the machine hang while goinf mutli-user?  Can you boot single user and then go multi successfully?

In the directory /etc there are several shell scripts that are executed depending to the level to which you want to take the machine.

There is a file called /etc/rc2 you can edit it to make sure every single step in the boot procedure is in a verbose manner.

The relevant part is the following:

if [ x$9 != "x2" -a x$9 != "x3" -a -d /etc/rc2.d ]
then
        for f in /etc/rc2.d/S*
        {
                if [ -s ${f} ]
                then
                        case ${f} in
                                *.sh)   .        ${f} ;;        # source it
                                *)      /sbin/sh ${f} start ;;  # sub shell
                        esac
                fi
        }
fi


Just add the -x option in the equivalent line above as in the example:

 *)      /sbin/sh -x  ${f} start ;;  # sub shell

and try to carry on in multiuser mode. You should see exactly where the machine is hanging and thus will be able to diagnose and troubleshoot  the problem.

Mmmm.

I don't have /usr/sbin/nsrd in my machine.

It may be something related to Legato Networker.

To find out to which software package does this command belong (if hopefully it was installed as part of a standard package) you can run the following:

grep nsrd /var/sadm/install/contents
