Veritas Multipathing problem.
Hi,
Basically the original configuration on my Solaris 9 server was two LUNs configured as Veritas file systems that were connected to a NetApp filer (filer1). These two LUNs are still configured on the server - but are not being used. They are there as a backup just in case the new configuration fails within the next week.
I have just created two new LUNs on a NetApp filer (filer2) and configured both of them as Veritas file systems. These two filers are in a cluster configuration. The problem is that the server is connecting to filer1 through Veritas multipathing first - then connecting through the partner connection to the LUNs on filer2.
How do I point VVM for the optimal path to filer2 where the new LUNs are located? Also the server has 4 paths to one LUN and only two to the second LUN? Any ideas?

my $qtree = $filer->create_qtree(

oplocks => 1,
mode => 0755,
security => 'unix',
);
# Alternately, you can create it, and then change things
my $qtree = $filer->create_qtree(
name => "/vol/vol1/qtreename",
mode => 0755,
);
# The mode must be set when created
$qtree->set_oplock(1);

Returns a string containing the current security setting of the qtree.
set_oplocks( $boolean )
This method takes a boolean argument, and sets the oplocks attribute of the qtree to "enabled" if the value is true, and "disabled" if the
value is false.
