One TB LUN from Eva 4100

[Albert Jose]

When I presented one TB LUN from Eva 4100, Server 2008 enterprise edition with SP2 shows that LUN as two LUN in disk management.Pls find attached screen shot and kindly advise a workaround.

Hi Albert,

I believe MPIO (Multi-path software) is not installed. You are seeing 2 LUNs because server has access to storage from two paths.

Install MPIO and issue will be resolved.

Windows 2008 already has mpio feature embedded, you need to enable this feature.

Or

you may also try installing HP MPIO DSM from below link

Hi,

Have you installed multipath on your server.

Thank you all for your inputs and I have solved this issue by installing MPIO software.
