 =head1 DESCRIPTION
 
-The B<copycds> command copies all contents of Distribution CDs/DVDs or Service Pack CDs/DVDs to the install directory as
-designated in the B<site> table attribute: B<installdir>.  The B<copycds> command can copy from one or more ISO files,
-or from the CD/DVD device path.  If xCAT doesn't recognize the signature of the CD/DVD (e.g. in the .discinfo
-file), you must specify the -n and -a options.  This is sometimes the case for distros that have very
-recently been released, and the xCAT code hasn't been updated for it yet.
+The B<copycds> command copies all contents of Distribution DVDs/ISOs or Service Pack DVDs/ISOs to a destination directory. The destination directory will be formed from the B<installdir> site attribute and the distro name and architecture, for example: /install/rhels6.3/x86_64. The B<copycds> command can copy from one or more ISO files, or the CD/DVD device path.
 
+You can get xCAT to recognize new DVDs/ISOs by adding them to /opt/xcat/lib/perl/xCAT/data/discinfo.pm and reloading xcatd (service xcatd reload).
