/dev/st0?

[Gorman, John]

I gave the wrong man pages last time, the man page with 
this information is mtio (which RH 6.1 does not have).

It is pretty standard, here is the one from Solaris 2.5.1

     /dev/rmt/<unit number><density>[<BSD behavior>][<no rewind>]
 
          density     l, m,  h,  u/c  (low,  medium,
                      high, ultra/compressed,
                      respectively) 
 
          BSD behavior (optional)  b
 
          no rewind (optional)     n
 
     For example, /dev/rmt/0hbn specifies unit 0,  high  density,
     BSD behavior and no rewind.

Hope that this answers the question on it.

|I thought the different devices controlled what level of hardware
|compression was being involved.
|
|/dev/st0 would be none or default
|/dev/st0l would be level 1
|/dev/st0m would be level 2
|/dev/st0a would be level 3
|
|Or something like that. Driver has to support it and all that. 
|Looks like
|I was wrong. It seems to me that the different devices was one way of
|controlling hardware compression under AIX, but I could be wrong.
|
|I need to be able to find out what settings my tape drive has 
|and then be
|able to change them :). I know how to do that in AIX, but that doesn't
|help me here.
|
|Turns out that there is a closed source util from the drive
|manufacturer. It isn't working right for me and I'd prefer to have a
|generic solution regarding tape drives in general.
