Hi all,

I am sorry if this question is obvious but I'm new to the camcontrol
utility. I'm just wondering if anyone has any comments on the following
commands.

root@goldberg 9:54pm ~ > camcontrol tags da0
(pass0:ahc0:0:0:0): device openings: 128
root@goldberg 9:54pm ~ > camcontrol tags da0 -N 64
(pass0:ahc0:0:0:0): tagged openings now 64
(pass0:ahc0:0:0:0): device openings: 64

Does this achieve what Justin suggested? Is 64 a good value of tag
depth or should I reduce it more?

Thanks,
-- long
