What do you mean when you say "nsrjb is too slow"? Are you seeing
long
delays before it moves the tape? What version of Red Hat is it? 2.4
kernel or 2.6?
If it is 2.6 it is a known issue, solution previously posted on
this list.
Davina;
Do you have any idea when this subject turned up? I don't recall. I
searched for "nsrjb slow" "nsrjb linux" and a few similar terms and I
get nothing relevant.
You can search for the string NONBLOCK and it will pull up about 4
hits.
I see references to adding the o_NONBLOCK option to st-driver, but I
have no clue where that is on my system. How do I modify the st-
driver? Google shows lots of hits, but so far, none actually explain
where the st-driver is located and how to change it on RH AS 4.
