The IDE drive is still recognized by the kernel, it just isn't made
available to the menu interface in RecoverEDGE. The drive can be
restored, but the steps would need to be done manually through the
Follow the instructions below to recover to perform a root only
restore & recover your primary drive.
1. Boot to your RecoverEDGE boot/filesystem floppies
2. Invoke the Utilities Menu > Shell.
3. From the shell prompt, type the following commands:
dparam /dev/rhd00 `dparam /dev/rhd00`
4. Perform an fdisk for your primary IDE drive.
fdisk -f /dev/rdsk/0s0
Make sure this is the IDE drive being accessed, if this is the
new IDE drive, you shouldn't see any partitions.
5. Create & activate your Unix partition, when complete, quit out of
fdisk to save your partition info.
6. The next step would be to run divvy on your hard drive, being it
is a new drive, run divvy in installation mode.
divvy -i /dev/rdsk/0s0
Create your filesystems exactly as they were on the previous
primary drive, keep in mind the size of the filesystems isn't
as crucial as the locations of the filesystems.
Before exiting divvy, make any adjustments you require and
install the filesystems as shown.
7. You may need to create a device node for RecoverEDGE to mount
your root filesystem. Do this by typing the following:
mknod /dev/hd0root b 1 40 (Unix 3.2v4.x)
mknod /dev/hd0root b 1 42 (Open Server 5)
8. Mount your root filesystem:
mount /dev/hd0root /mnt
If you are running Open Server 5 you would need to mount
your /stand filesystem also by typing:
mount /dev/boot /mnt/stand (Open Server 5 ONLY!!)
9. Begin the restore of your root filesystem only. This example
will assume you have a /u and a /u2 filesystem on the secondary
/bin/edge -xVbkfEE a b /dev/tape ./u ./u2
NOTE: a would refer to the block factor of your tape.
b would refer to the volume size of your data cartridge.
/dev/tape would refer to the device name of your tape
This will restore the root filesystems and exclude the /u & /u2
10. When the restore is complete, change directory and umount your
umount /mnt/stand (Open Server 5 ONLY !!!)
umount /mnt (Unix 3.2v4.2 & Open Server 5)
11. Finally, to be safe and possibly save time later, force a boot
track & master boot record. This too will need to be done from
the shell. Type the following
dd if=/etc/hdboot0 of=/dev/hd0a
dd if=/etc/hdboot1 of=/dev/hd0a bs=1k seek=1
12. Exit the shell, and select shut down from the RecoverEDGE menu.
Remove the floppies and reboot your system.
