SCO

Hi,

I am hoping someone can assist me please!
I need to create an emerceny boot disk after performing a SYSBAKP however I don't have a floppy drive on the server. Previously, someone created one to a CD to me however I don't know however I don't know how to do this.

Any feedback would be greatly apprecaited as I am quite unsure at the moment!

On SCO OpenServer release 6.0.0, and presumably Unixware 7.1 see the following:

#man emergency_disk

On 5.0.7 and older, you need to ensure that cdrecord is installed, and modify /usr/lib/mkdev/fd to create a diskette image rather than actual media, and then copy the image to cd.

This is directly from SCO technical Article #112505

Can I create my Emergency Floppies to CD rather than floppy?
------------------------------------------------------------
OpenServer 507 _does_ already have the mkdev fd option to create a
Emergency-CD !

See the 507 /usr/lib/mkdev/fd script and note the comment:

# hidden: 5. bootable CD (requires mkisofs, cdrecord) ...

So run "mkdev fd" and on the following menu:

Emergency Boot and Root floppy filesystems option
-------------------------------------------------

Choices for type of floppy filesystem.

1. 96tpi, double sided, 15 sectors per track (1.2M 5.25 inch)
2. 135tpi, double sided, 18 sectors per track (1.44M 3.5 inch)
3. 135tpi, double sided, 36 sectors per track (2.88M 3.5 inch)
4. 135tpi, double sided, 21 sectors per track (1.68M 3.5 inch)

Just press "5" and although not shown it will trigger the creation of
a bootable CD, including mkisofs image creation and cdrecord burning
when you select Single Boot&Root creation and System Specific Boot
(unless the boot kernel can't fit).

If you don't have a recordable CDROM installed, when prompted to enter
a CD to record to, from another console:

# cd /etc/bootroot.d

and you'll find all the files there, in case you wanted to burn the
ISO image using a Windows package, say, Nero on Windows, you'd need to
use the ISO image which is temporarily created as:

/etc/bootroot.d/bootcd.iso

But please note, that at the end of the mkdev fd script a function
called 'cleanup' is called and this will remove the $WORK directory,
which is defined to be /etc/bootroot.d, and as the iso image is in
there, you need to copy it to /tmp before the removal of $WORK.

--------------------------------------------------------------------

This has saved my a** on more then 1 occasion!

Eclectic wave

Did anyone create the bootable CD using above method?
