HP 9000 runnig Unix

I have aquired the dutties of looking after our MRP system
We have a HP 9000D running Unix With MINX as tha MRP system
Our last IT System adim. had crashed the system before he left
and sense then we have not been able to log on to the system at the console or remotely. tha error reads minx 460 not found
and it wants us to log on as root to run fsck manualy.
the real problem is that we can not access the root the sysytem says the root has been disabled. How do I fix this problem so I can enter the system to do a manual fsck on the files that have errors.
any Help would be great.

First of all, let me say that there is a great website for HPUX.
www.itrc.hp.com Go to the search page and type in your problem and click on the criteria you want to search for answers. The forum and manuals are good ones to pick.

Okay, here's the situation. Is this running HPUX? What version? What is the MINX product? Is that an application?

I will assume you have a version of HPUX.

You will have to do one or more of several things.

Regarding the disabled root, You can fix this when you log back in to single user mode. Just create a password for root using " passwd root " command.

First, we will try the easiest thing. Reboot the box, power off and power on again. When the box is coming back up, there will be a point to break in and stop the boot process. Do this.

Now, depending on what version of unix you are running, you will want to get to single user mode.

If you have a menu there, type in whatever it asks for to get you to single.

In HPUX, type " hpux boot -is " or " hpux -is ".

When you get there, perform fsck on all the filesystems. Do a man on fsck if you have another box. Here is some of that man page.

fsck(1M) fsck(1M)
fsck (generic) - file system consistency check and interactive repair

/usr/sbin/fsck [-F FSType] [-m] [-V] [special ...]
/usr/sbin/fsck [-F FSType] [-o FSspecific-options] [-V] [special ...]

The fsck command audits and interactively repairs inconsistent
conditions for HP-UX file systems on mass storage device files
identified by special. If the file system is consistent, the number
of files on that file system and the number of used and free blocks
are reported. If the file system is inconsistent, fsck provides a
mechanism to fix these inconsistencies, depending on which form of the
fsck command is used.

special represents a special device (e.g., /dev/rdsk/c1d0s8).
fsck recognizes the following options:

-F FStype Specify the file system type on which to operate (see fstyp(1M) and fs_wrapper(5)). If this option
by matching special with an entry in that file.
system type is determined from the file /etc/fstab
by matching special with an entry in that file.
If there is no entry in /etc/fstab, then the file
system type is determined from the file

-m Perform a sanity check only. fsck will return 0
if the file system is suitable for mounting. If
the file system needs additional checking, the
return code is 32. If the file system is mounted,
the return code is 33. Error codes larger than 33
indicate that the file system is badly damaged.

Now, if that doesn't work you will need to have a CDROM or backup tape to restore from. Reboot the box, and have either the CDROM or tape in the system. Break in as before during the boot cycle, and boot from the tape or CDROM.

You may have to reinstall via the CDROM if you don't have a tape or can't restore from it.

My fear is that your old admin has sabotaged your box. Smilie
You may have to reinstall, if when you get to single and see that filesystems are missing.

Please respond with your progress!!Smilie

I tried to do what you Suggested I was able to get to the single user mode and to ru fsck all went well but the /dev/vg01/rminx460 could not open
As for the change of the root I did passwd it asks for the old password I entered it and it said SORRY.

So the system is still not operating.

The system is HPUX I don't know what version
The Minx System is an MRP system that runs in unix
it is an old system not used any longer.
Thanks for the help.

If you're in single-user, you should already be root, right?
If "passwd root" doesn't work, you could always edit the /etc/passwd file. There will be an entry at the top similar to this:
root:[random junk here]:0:0:Root:/:/sbin/sh

Where the seemingly-random junk is, between the second and third colon ( : ) is the encrypted password. Simply remove everything in there so it looks like this:

Now root has no password. Try changing it now.

I don't know very much at all about LVM, as it seems to suggest you might need help with as far as the /dev/vg01/rminx460 entry goes.
Is there any chance he simply wiped the disks in anger (possible if he harmed the system purposely in any other way), or even simply remove the disk? If you can get /usr mounted, you should be able to use: "/usr/sbin/fstyp /dev/vg01/rminx460" to see if a recognizible filesystem exists there...

Hope this helps a little... Maybe someone better with HP-UX can provide more info...

Good point! Livinfree!

After you do that, try the fsck again. Then try to find the /dev/vg01/rminx460. What filesystem is this related to?

If this is a root-related disk, you might have to reload from a CD or tape.

Don't give up now!

BTW, if the old SA has maliciously crashed/sabotaged your system, your company can and should bring charges against them.

Just my opinion though...

OK I have done all
But I am not able to access the rminx460
I have the last Tape back up
But I do not know how to run the sysytem from the tape
Any Help!!

It depends on how the tape was created. Also, is it a backup of the root volume or of the whole box?

If this is HPUX, look in /usr/sbin or one of the other binary directories for a command that may work.

tar, frecover, and make_recovery are three commands that can work on HPUX boxes.

If you can do a " uname -a " and print the output here.
