Hello,
we have v490 running Solaris 10 Update 3 with 4Gbit Qlogic HBAs
connected to EMC dmx3.

'vxdisk list' shows that only one path is used.
'vxdisk path' shows all paths.

Now I would like to know how to tell Vertias DMP to use more than one
path for i/o.

Has maybe the udid_mismatch something todo with that? How can I solve the
problem. I have another box where it works and does not show udid_mismatch.
