Win2k3 see's duplicated LUNS MSA1000

Hi There,

We have configured a LUN to be presented to Win2k3 from the MSA1000 but Win2k3 see it twice.

Any ideas??

Cheers

It sounds like you have dual paths going to the MSA from the server.
If you do you would need to install a pathing software like Securepath or MPIO from microsoft.
Alternatively, you could also do a single path but you would not have redundancy.

Lance:

Can you give anymore details?

Nicholas is correct in saying that you are seeing 2 paths to the same device and that you need some multipath software, but I like to take it a step further and make sure your have a supported configuration... unless of course you do not care about support.

Do you have 2 SAN switches? dual hba's?

Secure Path is purchasable from HP.

MPIO is free from HP, but is less robust.

Hi Guys,

Problem solved. Topology was set incorrectly on the HBA. Also old drivers for the Emulex card.

Thanks for your help.
