Is HP DSM built by their own or on top of MS MPIO?

 

We experienced an error on cluster/MPIO "All paths have failed. \Device\MPIODisk2 will be removed.". I google and find someone encountered the same error but I am runnig HP DSM(MPIO).

Windows 2008 R2 bug?

Should I update MPIO to 6.1.7601.17619? Is HP DSM built by their own or on top of MS MPIO(see to be the latter, right)?

DSM = Device Specific Module.  Think device driver for MPIO, they work together, DSM is no use without MPIO and vice versa.
