[ofw] WinOFED SRP Location Path and Target Number

[John Carbone]

I'm running Windows 2008 R2 will all updates applied, WinOFED 3.2, with just Core Modules and SRP installed, and Mellanox all MHQH29C-XTR cards with latest firmware. I have the SAN policy set to Offline Shared.

I have 3 targets with one LUN each. In Windows when I do "detail disk" in diskpart.exe for each disk the Targets are all 0 and the Location Path is UNAVAILABLE. However, vmware sees the targets with unique numbers.

I think that this might be causing a problem with Windows not being able to distinguish between the disks, and makes it very difficult for me to identify the disks myself.

Included is the output of vstat, and the disk detail of two of the disks.

Is there anything that be done to address this issue?
