check /var/adm/messages for any error log.

also try and boot the system from single user mode
that is issue

boot -s from the OK prompt

then run fsck on the filesystem

that is fsck /dev/dsk/c0t0d0s0

or fsck /dev/dsk/c0t0d0s2

fsck will report any problem with file system and prompt you for a fixed.
just answer yes for fsck to fix filesystem problem

and finally issue

sycn
sycn
sycn

then boot system in multi users mode
issuing a reboot command or init 6
will boot system in multi users mode

REBOOT(8)						      System Manager's Manual							 REBOOT(8)

NAME
reboot - reboot the system immediately SYNOPSIS
reboot [-f] DESCRIPTION
Reboot can be used to reboot the system after installing a new kernel. It does not inform the users, but does log it's actions in /usr/adm/wtmp and /usr/adm/authlog. The system is then rebooted with the reboot(2) systemcall. If the -f flag is not given then all processes are sent terminate signals to give them a chance to die peacefully before the reboot() call. If the wtmp file exists, reboot logs itself as if it were a shutdown. This is done to prevent last(1) from talking about system-crashes. Reboot is registered as is in the authlog file. Reboot can only be executed by the super-user. Any other caller will be refused, either by reboot(8) or by reboot(2). SEE ALSO
reboot(2), shutdown(8), halt(8), boot(8). BUGS
The error message's given by reboot are not always useful. There are several routines that can fail, but which are not fatal for the pro- gram. AUTHOR
