I've got some 2008 boxes...nothing R2 yet. As someone has already mentioned, once a server has been zoned to the array, disk management will list several disks. Usually, installing PowerPath and scanning for hardware changes (or rebooting) will update disk management and present the correct disks based on the number of LUNs assigned.
If you're still seeing issues, I would have the appropriate person review the zoning config on your fabric while your SAN guys verifies the host connectivity on the DMX. I'm only familiar with the CX line from EMC but I'm assuming the management interface has the ability to check the connectivity status and to make sure each path is logged in and registered with the array. I've also seen odd behavior like this when a host is assigned to a storage group on the array but no LUNs have been assigned. - Sean On Thu, Jul 29, 2010 at 4:32 AM, Ziots, Edward <[email protected]> wrote: > Folks, > > > > Is anyone out there using EMC powerpath with Windows 2008 R2, to present > LUN’s from an EMC SAN to servers/Clusters etc etc? > > > > My SAN Guy, basically is telling me that the role service of Multipath I/O > is added to the server when the EMC Powerpath is added but when the drives > are presented we are seeing two disks in disk management, not one, which the > Multipath software in EMC Powerpath is supposed to take care of.
