Do you want to actually delete the data, or do you want to suppress it 
from being displayed on the graphs?

I handled it on my machine by constraining the data via a regexp to the 
"data" line in the plot in question.  For example, all my internal disks 
(and only my intenral disks) show up as c#t#d#, so I made a distinct 
plot for them:

plot {
title                   %g Disk Run Percent Internal Disks
source                  orcallator
data                    disk_runp_((?:c1t\d+d\d+))
line_type               line2
legend                  $1
y_legend                Run Percent
data_min                0
data_max                100
plot_min                0
plot_max                100
href

}

You could do something similar for your mirrored disks, using an 
appropriate regular expression.  Maybe something like this:

data                    disk_runp_((?:md\d))

Though I didn't test that syntax, so it might not work as-written.

As for the disk usage, which uses mountpoints, you'd probably want to 
exclude temporary mounts like things in /mnt.  For example, in my disk 
usage plot, I don't want to see the Veritas checkpoints I maintain, 
because they'd give me redundant information anyway (same #s as the base 
filesystem they're checkpointing).  So, I do this to exclude them:

data            mntP_(?!/(?:vxckpt|checkpoints|veritas))(.*)

In your case, it would look a bit simpler, most likely:

data            mntP_(?!/mnt)(.*)

Though I didn't test that syntax, so it might not work as-written.

Hope this helps,
