find out trusted system root passwd

axiaonet

#1) Once you remove the hard drive from the system that you cannot log onto as root, change the SCSI address jumper on the drive to something other then ID 6 -- since more then likely the system you hook the drive up to will be using SCSI ID 6 for it's boot drive.

#2) Once you hook the drive up to the live system, you will want to do a ioscan -fnC disk to determine the address and device file of the new drive.  Your output for this command will resemble this:

# ioscan -fnC disk | more
Class     I  H/W Path      Driver      S/W State   H/W Type     Description
============================================================================
disk      0  8/0/19/0.2.0  sdisk       CLAIMED     DEVICE       IBM     DDRS-345-60WS
   
                      /dev/dsk/c0t2d0   /dev/rdsk/c0t2d0

disk      1  8/16/5.6.0  sdisk       CLAIMED   DEVICE    SEAGATE ST32151N
                        /dev/dsk/c0t6d0   /dev/rdsk/c0t6d0

disk      2  8/16/5.2.0    sdisk       CLAIMED     DEVICE       TOSHIBA CD-ROM X
M-6201TA

                          /dev/dsk/c1t2d0   /dev/rdsk/c1t2d0

In the above system there are three disks.  For your case, more than likely the c0t6d0 is the boot disk and the other non-CDROM disk would be the one you just installed in the system (/dev/dsk/c0t2d0) (SCSI address 2).  Once confirmed that the new disk is there and correct you should be able to mount it:

mkdir /disc
mount /dev/dsk/c0td20 /disc

Once mounted you can access the password file on the second disk by entering vi /disc/etc/passwd

Make the root password line in this file look like this:

root::0:3::/:/sbin/sh

Write and quit this file and when you hook the drive back up to the machine you took it out of you should be able to log on as root without having to enter a password
