formatting magneto optical for hp-ux & linux, possible?

[Masaki Birchmier]

Is it possible to format a magneto optical disk from hp-ux so that it can also be read from a linux system?

Non LVM format was not readable by linux.

Thanks,
Masaki

Not tried it personally, but you cannot use these optical drives using LVM structures. You can configure these disks without using LVM in HP-UX:

1) Run mediainit if needed.
2) Run newfs on the disk:
# newfs -F hfs /dev/rdsk/cxtydz
3) Mount:
# mount /dev/dsk/cxtydz /mount_dir

You can have either hfs of jfs file systems on these disks. I am not sure whether this will be mountable on linux.

This will be useful for you:

The quick answer is no, there is no file system format available under HP-UX that is readable under Linux.

That said, you *could* use the M-O drive as a sequential medium. Tar, dd, cpio, etc., all could be used to write files to an M-O disk which is then readable under *any* other computer system having those same programs.

I was afraid that it was the case (no can do..)but wanted to double check.

Yes, I have resorted to the fact that I will have to use it like a sequential medium (tar, cpio, ...) if I want to use it with both HP-UX & Linux.

Thanks for your help.
