Auto-Virtual Disk Transfer (AVT)

I/O data path protection to redundant  in a  is accomplished with the Auto-Virtual Disk Transfer (AVT) feature and a ?? .

AVT is a built-in feature of the RAID controller module  that manages individual  on a storage array. When it is enabled and used in conjunction with a host multi-path driver, it helps ensure that an I/O data path is available for the virtual disks on the storage array.

If there is a component failure or some other error occurs on the data path to the preferred RAID controller module, AVT and the multi-path driver automatically transfer the  and virtual disks to the other "non-preferred" RAID controller module for processing. The virtual disk transfer is logged as a critical event in the . Once the I/O data path problem is corrected, the preferred RAID controller module will reestablish ownership of the disk groups and virtual disks.
