The controller number is referred to as a 'VBUS'.

Each cXtYdZ will not map directly to one "Hard Data Drive". They map to LUNs which are most likely striped in some way (RAID5 or RAID 0/1) over many "Hard Data Drives" Mon, 04 Aug 2003 18:28:06 GMT https://community.hpe.com/t5/disk/emc-disk-mapping/m-p/3039075#M4084 Michael P_1 2003-08-04T18:28:06Z
