Copying hard drives

0.

Gather together slotted and Phillips screwdrivers and a soldering kit.

1.

Make a tar file of the drive you wish to copy.

2.

Transfer the tar file to the working VXI controller on which you will physically make the copy.

3.

Open up the working VXI controller and remove the existing ISA cable that connects the mother board to the hard drive.

4.

Find another ISA cable with three heads on it with the appropriate number of pins (such as from a sacrificial x86).

5.

Move the jumper on the target hard drive from the center pin (DS) to the end (SP). Not sure if this is necessary, but it seems like it ought to be.

6.

Connect this cable from the mother board to the second hard drive and back to the original hard drive.

7.

Find a spare 4-spaded disk drive power supply cable at least 10 inches long. Strip the leads of the cable and solder it onto the VXI power circuit in parallel with the existing hard drive leads. The two central black wires are (identical) grounds, while red should go to red and orange to orange/yellow.

8.

With the cover remaining off, slide the VXI controller into slot 0, and let the second hard drive sit next to it.

9.

Run ``setup'' and select for Disk 1 the appropriate parameters. We guessed and used the same values as for the existing Disk 0: [Auto] CY:[723] HD:[13] ST:[51] LZ:[723] WP:[None]

10.

After booting LynxOS, run ``mkpart'' on /dev/hd1

11.

Run ``mount /dev/hd1 /mnt'' to mount the disk to /mnt

12.

Run ``mkfs'' on /mnt

13.

You should now be able to see the drive in commands like ``df''

14.

Change directory to /mnt and ``tar xvf'' your archive

15.

Run ``makeboot preboot''

16.

Shutdown, disconnect the target hard drive, move the jumper back to the center position, mount it in its VXI controller, plug it in and hope that it boots.
