When mapping a volume from my SAN to a Server 2008 R2 Host, it appears twice, Multipath is configured and installed, what am i doing wrong?
Posted on 2011-10-26
Just looking for some advice. Its been an issue for a while, and although i have a workaround, i want to know the opinion of someone who knows a little more about this.
I have some HS22 Blades, in a BladeCenter E Chasis, which connect to a V7000 IBM SAN.
My problem is, i have 2 Fibre cards in each Blade. These have two viewable mac addresses in the Storage Explorer. If i map both MAC's to a host, the volume will show up twice. I have the Multipath I/O installed and the HBA drivers setup.
Im not sure if this is a failover feature im looking for outside of the functionality of this system, or if i am doing something wrong.
We had a technical consultant come in, and only map 1 MAC address to the Host, meaning it was showing once, but multipath doesnt appear to work. Because if you pull out a fibre connection, the systems go offline.
Any advice on this would be very much appreciated.
