Unregonized filesystem

[Jonathan Caplette]

Hi guys,

I try to mount a magneto-optical disk on an HP system, but when I mount it, I obtain this error: /dev/dsk/c#t#d# : unregonized filesystem... What I suspect is that the disk has been formatted, and written when the magneto-optical was on an old IBM... What I wanna know is, can I in some way to mount a filesystem that I don't know the type??

Thanks...
Jon

run the fstyp on the device file and that should show you.

hey,

U may need to run 'mediainit' for using this.

Check this for a complete guide for administrating Magneto-optical disks:

Hi Jon,

I'm having to go back about 6 years to when I supported an optical jukebox on AIX. The software we used, AMASS, presented all the optical disks to AIX as a filesystem. The individual disks were not mounted as individual filesystems.

So my question is, do you know the optical disk was actually written as a filesystem? You probably need to investigate how the disk was actually written.

Hello,

aiming in the same direction as the previous reply:
could it be that MO disk was used in a "VBFS" (Very Big File System) = HP OmniStorage?
Then it is only part of filesystem - not a complete one of its own. And you'll need the additional software (for OST see: http://www.openview.hp.com/products/omnistorage/index.asp )

HTH,

What you can try is:

dd if=/dev/rdsk/... of=/tmp/record bs=8k count=1

file /tmp/record

od -bc /tmp/record | more

and check if the file(1) command can make sense of it or/and the od(1) output gives some clue.
