The virthba module provides access to a shared SCSI host bus adapter and one or more disk devices, by proxying SCSI commands between the guest and the service partition that owns the shared SCSI adapter, using a channel between the guest and the service partition. The disks that appear on the shared bus are defined by the s-Par configuration and enforced by the service partition, while the guest driver handles sending commands and handling responses. Each disk is shared as a whole to a guest. Sharing the bus adapter in this way provides resiliency; should the device encounter an error, only the service partition is rebooted, and the device is reinitialized. This allows guests to continue running and to recover from the error.
