PERC H740P controllers supports RAID mode and Enhanced HBA mode.
When the controller is in Enhanced HBA, it creates single disk
RAID0 virtual disks of NON-RAID physical disks.
Hence the user's request for VD creation with supported RAID
fails due to no available physical disk.
This patch checks the Perc H740P controllers whether it supports
enhanced HBA mode and if controllers are found in enhanced HBA
mode it converts back to RAID mode.
