this is interesting also any procedures on how to do this from the AIX side
of the house would be helpful as well. Thanks!.

Currently running tsm 4.2.1 on solaris 8.  Have approx 6gb database split
into two volumes, each mirrored.
Using standard filesystem based volumes.  a few questions.

1.  Is the performance increase worth the time and hastle to convert to raw
volumes?

2.  Can I mix and match?  i.e. create a temp volume, delete dbvol1, create
a raw volume in its place, then delete the ttemp volume to move the data
back?

3.  Just how do you specify the raw partition?  Tried it before
/dev/rdsk/c2t3d0 for example, but no joy.

Thanks for any information you have.
