After reading a little bit and trying different thinks, I had installed
a new SCSI Hard drive on my SCO 5.0.7 (a 5th SCSI disk)
I know now that I have 5 disks at the beggining I had 3 hard disks on a
RAID5, now I have a 4th disk added to the RAID5, and the 5th outside of
the RAID, the disk number 4 (inside of the RAID) SCO can not see it.
What shall I do to make SCO read the new part of the RAID (I am using
RAID5)
I read http://aplawrence.com/Unixart/moredisk.html but I can only add a
new hard disk but I need on a RAID5 for redundancy...
These are the disks I have, but I am a bit confused because I had taken
the 5th hard disk out to be sure that I am going to format the right
hard disk, and I had the same information that is shown below.
What I want to do is make the /root partition twice bigger...
Thanks for your help...

I had tried to find out how the SCSI arrange disks are in the SCO

I tried "df" command but it just gives me the file systems that are
mounted.
I also tried "df /dev/hd* " and "df /dev/hd* " but the result is:
df -k /dev/hd*
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 139909664 117870041 22039623 85% /
/dev/root 139909664 117870041 22039623 85% /

df -k /dev/hd* ¦ wc -l
29
......so 28 hard disks, but I have 4 or 5 SCSI on the SCO computer.
Do you have a solution?
I want to know where is / mounted and how can I add a New SCSI Hard
Disk
Thanks
To help determine disks in your system:
1) hwconfig should show you how many disks are configured (if they are
all SCSI, try 'hwconfig | grep Sdsk').
NOTE: This gives you the disks configured within the OS, not the
physical number of disks in the box.
ALSO NOTE: if the disks are attached to a RAID controller, this will
only report the number of *logical disks* configured within the OS.
You will need to use your RAID controller's utilities to determine the
number of disks it is offering to the OS (this should also tell you
how many *physical disks* are attached, and how the logical disks are
configured).
2) Try running 'sconf -v'. See "ALSO NOTE" above as it applies here.
And to add hard disks:
