MSA 2040 (SAS) - Windows 2012 R2 detecting RAID Bus type

Hi,

 

Just setting up a new Hyper-V cluster. 

 

I have the following Hardware/software setup:

 

  • HP MSA 2040 (SAS) Dual controller.
  • 2 x HP DL380 Gen9.
  • 1 x HP Smart Array P441 in HBA mode per DL380.
  • 2 x Mini SAS connections to MSA 2040 (controller A and B) per DL380.
  • Windows Server 2012 R2.
  • MS MPIO (SAS support ticked) feature  installed.

Both of my hosts can see the volumes that I have mapped from the SAN and both detect the volumes as 1 drive ( meaning the MPIO is working). However the Bus type for the drives is reported as RAID, I was expecting SAS?

 

Is this to be expected, or have I missed a configuration step somewhere? This means I have to make a registry change for the Cluster validation tool to accept RAID type bus Disks as storage for the CSV. This all works and I can make HA VMs but I don't want to put this into production if this should be reporting the bus type as something else though.

 

Hope you can help!

If you lookup the quickspecs http://www8.hp.com/h20195/v2/GetDocument.aspx?docname=c04123144 you will find in "Step 4b" all supported server controllers, but not yours. However, assuming this is not a problem, the server can see LUNs, not disks, hence the server is probably right and sees RAID volumes, because the server cannot see the disks itself, but LUNs only.

 

and:

 

...

Refer to the HP support statements for complete current OS version support:

 


Hope this helps!
