Err#13 EACCES
After analyzing the truss output found issue with the file permission, most of the directories base directories like /var, /, /etc, /usr, /bin didn't have execute permission. I corrected them, but with the /dev and /devices directory the permission are correct but I get the the error in truss.

su2.out is the out put of the truss command
Code:
# grep EACCES su2.out | head

19964/1:        47.6592 stat64("/dev/ptyp0", 0xFFBFFA58)                Err#13 EACCES

# ls -l /dev/tty
lrwxrwxrwx   1 root     other         26 Nov  4  2005 /dev/tty -> ../devices/pseudo/sy@0:tty
# ls -l /devices/pseudo/sy@0:tty
crw-rw-rw-   1 root     tty       22,  0 Aug 11 17:37 /devices/pseudo/sy@0:tty

# grep EACCES su2.out | grep /dev | wc -l
    1286
# grep EACCES su2.out | wc -l
    1287

Also during login attempt I got the error "/dev/null: cannot create" and "ksh: /dev/null: cannot create" . I verified the permission it was correct and I re-applied the same permission for those files. These two errors vanished. But now I have to the same to 1286 files in /devices and it's link /dev. I tried with devfsadm command, but no good the problem still persist. Could you suggest any script to read all the file permission for files under /dev and /devices and re-apply the same? or read the /dev/* from the truss command output file and re-apply the files permission and also do the same to its relevant /devices file?

Code:
# ls -l /dev/null
lrwxrwxrwx   1 root     other         27 Nov  4  2005 /dev/null -> ../devices/pseudo/mm@0:null
# ls -l /devices/pseudo/mm@0:null
crw-rw-rw-   1 root     sys       13,  2 Aug  9 19:04 /devices/pseudo/mm@0:null
