Question on disk device files on non SGI disks

[jaholden]

Hey all,

A friend of mine has asked if I can dd image a SCSI disk he has.

It‘s not SGI partitioned or formatted, maybe MBR or Sun. Will it show up as only /dev/dsk/dksXdYvol where X and Y are controller and device?

ie: I can dd the whole disk from start to finish regardless of partition scheme.

Thanks,

j

Edit: With apologies, I no longer wish to have involvement with SGUG or SGI communities in general,
and have also chosen to remove all of my content. Many things have changed since I co-founded, named, and ultimately
then left SGUG. There are many good people around, to whom I apologize for frustrating by removing these things, and
also many petty people that over the years whittled down both the enjoyment as well as sense of obligation I used to
feel to anyone else regarding what was ultimately just a hobby. Unfortunately one of the latter now writes the rules
and so it is time for me to take my things and go.

This message will replace all of my previous forum posts because deleting threads that I started would have removed
other peoples' posts.

Although I have not tried attaching a disk without an SGI disklabel in IRIX, I expect you would see the vol device show up and that does represent the entire disk. Perhaps verify the size of the dumped file?

Thanks! That’s what I suspected. I guess I’m looking for a the equivalent of /dev/sdX on Linux.

I suppose another way of putting it would be “how does Iris see an unpartioned disk?”

Hiya!

Sure you can just plugin the drive and it will allow you to access it through raw and cooked mode for both *vol and *vh (at the very least). This should be enough to dd it.
