I would like to know how to backup an existing SCSI hard drive onto
another SCSI hard drive on a UNIX system.  Currently the file system
is read-only.  How do I change the security permissions on the
filesystem?  I logged in as root but this didn't work.  I noticed that
this system does not have the cfdisk or fdisk utility.  Is there any
other UNIX utilities I can use to format, partition, and mount the new
hard drive?  Once this is done how do I make an exact copy of the
original hard drive onto the new hard drive?  Do I use the dd command?

Thank you.

Let me guess there is bank records on it? You're mate works in a bank, he pu

The dd command is the easiest way to do it.  Assuming the original
hard drive is /dev/rd0a and the spare hard drive is /dev/rd1a:

dd if=/dev/rd0a of=/dev/rd1a seek=1 skip=1 bs=8k

When this finishes,

fsck /dev/rd1a

mount /dev/d1a /rootb

Kind regards,
Nancy

Perhaps the file system became read-only because of an i/o error.
Try "mount -n -o remount,rw /"

I entered the command uname -a to get

LynxOS Orbis  2.2.1    2    m68040

I looked through the /bin and /usr/local/bin directories and could not
find anything related to fdisk.  Is there another disk
formating/partioning utility in this version of UNIX?

I also looked in the /etc/fstab file which has contents

/dev/sd0a:/:rw:0:0
/dev/sd0b:/home:rw:0:0

Somebody else told me that the command

mount -n -o remount, rw /

will solve the read-only file system problem I'm having.

Any help on this would be appreciated.

Thanks.
