3.1.1.11. UFS

Universal Flash Subsystem (UFS) devices show up as scsi devices similar to SATA in the previous section. One additional command to initialize all ufs devices is:

::

=> ufs init Device at ufs@4e84000 up at:[RX, TX]: gear=[3, 3], lane[2, 2], pwr[FAST MODE, FAST MODE], rate = 2

Then we can go ahead with ‘scsi scan’ to see the attached devices:

  => scsi scan
  scanning bus for devices...
Device 0: (0:0) Vendor: TOSHIBA Prod.: THGAF8G8T23BAILB Rev: 0300
          Type: Hard Disk
          Capacity: 31.9 MB = 0.0 GB (8191 x 4096)
Device 0: (0:1) Vendor: TOSHIBA Prod.: THGAF8G8T23BAILB Rev: 0300
          Type: Hard Disk
          Capacity: 30499.9 MB = 29.7 GB (7807999 x 4096)

All the remaining scsi commands detailed in the previous section are also applicable.
