A system may fail to boot properly if permissions, groups and owners are accidentally changed using the chmod and chown commands on operating system files or directories.
Possible errors reported include:
permission denied errors
cannot execute /usr/lib/ld.so.1 Killed
Can't invoke init, error 13 (the system would then panic)
Filesystem state in superblock wrong
Or it may not be possible to login into the system:
This document details how to reset the Solaris Operating System permissions, groups and owners back to the default values to allow the system to boot again.
Make certain that you know the system's root file system type and configuration before beginning. Is the system using UFS or ZFS root?
If UFS root, you will need to know the system's file system configuration e.g. what OS file systems are configured and the /dev/dsk/c#t#d#s# for each OS file system. These may include: /, /usr, /var, /opt
If ZFS root, you will need to know the pool name for the root pool (the default root pool name is rpool)
