I tried some more but still no luck

tried as suggested with the following (same)result

I have tried a couple of different things, using /dev/sdc1 directly,
creating a 250 gb lv called /dev/tsm01/tsm01. Using the raw command on
the lv, using a 15gb partition on a different scsi controller.
It all gives me the same result. (above)

Could it be that raw volumes are not supported under linux? Or am i
missing something.

Mark:
I wanted to use raw volumes for my diskpools since formatting  3 tb with
dsmfmt on a normal filesystem takes a very long time and using the file
device class would result in more overhead. (reclamation, wasted
diskspace, and so on). If the raw volumes are not going to work soon i
will use the file device class but don't really like the beauty of it.

Thnx

I'm trying to create raw volumes under linux
I have a 1700 GB disk called /dev/sdc
i tried: raw /dev/raw/raw1 /dev/sdc
when trying to add the volume in tsm i get this.

ANR2017I Administrator ADMIN issued command: DEFINE VOLUME
POOL01 /dev/raw/raw1 ACCESS=READWRITE FORMATSIZE=1715814

If using raw volumes for TSM with Linux follows the patterns for AIX,
try

  def vol pool01 /dev/raw/raw1

You don't run a format on raw volumes; doing so makes TSM think that the
target is a defined filesystem (which a raw volume isn't).

I'm curious--why are you using raw volumes?
