Error ignoring dupe of package_name

[deaw0003]

After i run command
dtmrepo -augfv -d rhel6s-86_64
I found error about ignoring dupe of package_name.That make these pakage not sync.

That is not an error. That is a time-saver otherwise it would redownload hundreds of gigabytes of already downloaded packages every time.

But I fond if this meesage occur. Amount of total pakage after repolist dtmrepo itself isn't equl to repolist from CDN Red hat.
although I sync dtmrepo to latest (Red Hat 6)

Use the mirror option

[deaw0003]

Where can i add mirror option ?

I suggest that you completely read instructions.txt before asking another question.

[deaw0003]

Yes, i read instruction already.But i don't know where add to INSTALLDIR/etc/dtmrepo.conf.d that contain dtmrepo config file such as
[control]
releasever = 5Server
arch = x86_64
keep = 2
protectrepo = os,optional

[repos]
os = rhel-5-server-rpms
optional = rhel-5-server-optional-rpms
supplementary = rhel-5-server-supplementary-rpms
epel = epel-5-x86_64
foo = local:/var/dtmrepo/foo/el5/x86_64
misc = swalk:some-spacewalk-channel
dev = mirror:dev-el5

or add mirror in /etc/yum.repo.d/ in server that need to repolist/upgrade such as
[epel-5-x86_64]
name=epel-5
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=x86_64
failovermethod=priority
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-5
