Hello all,
I’ve configured MPIO on a Win2k8 R2 and added several Clariion volumes in it.
To install Clariion DSM, I installed EMC PowerPath 5.7.1 SP1 software. Added "DGC RAID 5" and "DGC RAID 10" in "MPIO->Discover MultiPaths" tab. Then claimed the disks viampclaim.exe -r -i -a "" command.
I’m not able to make the Clariion Volumes to be claimed by MPIO. (MPIO’ed for Clariion volumes is False):

Here if you notice, “System Disk” is N\A for Clariion volumes and “MPIO’ed” is No.
To solve this issue, I disabled PowerPath services and claimed (mpclaim.exe -r -i -a "") again and rebooted machine. But the output remains same.
Any help or suggestions to resolve this issue are welcome…
Thank in advance
