Backing up a 9.0 root harddisk from a 10.x system???

[Sajith Mannadiar]

Hi,

Is it possible to backup the root hard disk of a 9.0 system from a 10.20 server
(with utilities like make_recovery or copyutil??

I want to upgrade the root harddisk of 9.0 system with a 1GB hard disk and we
don't have the 9.0 OS tapes with us.

This is the only 9.0 system in our lab and we need to upgrade this to 9.10 for
y2k compliance.

Please help us.

Thanks
Sajith

Hope I can help here. It has been awhile since I worked on a 9.x system let
alone a 400. This is my suggestion.

1. First hook up the new 1GB SCSI drive to the system with the old root disk.
If the SCSI id on the root disk is 6 then use something else for the 1GB drive.

2. I assume you have a correct disktab entry in the /etc dir. If not you need
to add the 1GB parameters to this file.

3. newfs the 1gb drive referencing the disktab entry.
here is an example:

newfs -L -m5 /dev/rdsk/??????? 1GB_with_swap

4. run mkboot /dev/dsk/??????? on the new 1GB disk.

5. Go to single user mode and from the root / directory mount the new drive to
some temp mount point and then use cpio to copy the contents of the 300MB drive
to the 1GB drive.

find . |grep -v /tempmnt | cpio -pudmvx /tempmnt

6. When it is done remove the old drive and set the new drive up with the same
SCSI id as the old root drive. Power back up and hopefully it will boot.

Like I said it has been awhile so anybody out there see any mistakes or
something I have forgotten please respond.

Hi Mike,

Thanks a lot for your input. Let me try this out.

If I get some new information, definitely I'll let you know.

Currently I am in Ottawa and I'll be trying this out once I go back to India
(i.e,on 28th).

But what about the tools ???? Any ideas???

I don't think you can run any ignite-UX utils or other recovery tools from 10.x
on a 9.x platform especially because the 400 uses a 64000 series Motorola
processor and 10.x is made for PA-RISC CPU's. The binaries would have to be
recompiled which would require source code which is not available from HP. 9.x
did come with some kind of disk to tape copy but I don't remember what it is
called. Perhaps someone else on the forum remembers.

From the 9.00 machine, use remsh executing the dd command to read the tape from
the 10.20 machine and putting the contents into a file on the 9.00 machine
(assuming you have enought room.) You can then use the file as a depot for
swinstall.
