USB mass storage

Universal Serial Bus (USB) mass storage devices are exported by the Virtual I/O Server. This topic gives information about the types of supported USB devices and configurations.

The Virtual I/O Server exports the USB attached hard disk devices to the client logical partitions. These exported devices are referred to as virtual Small Computer System Interface (SCSI) USB disk devices. The virtual SCSI USB disk devices are backed up by the physical USB mass storage devices. The virtual SCSI USB disk is used to back up or restore data of the client logical partitions. These disks can also be used as a boot device.

The virtual SCSI USB disk devices are assigned to only one client logical partition at any given time. To use the device on a different client logical partition, it must first be removed from its current logical partition and then reassigned to the logical partition that uses the device.
