>Environment:

2.2.6-RELEASE, Pentium/PCI-based system with Symbios Logic SYM22802 SCSI
controller and Transitional Technologies Q47 DLT robot.

>Description:

The CHIOGSTATUS ioctl of the SCSI media changer driver (sys/scsi/ch.c)
is broken.  It omits the SCSI_DATA_IN flag in the SCSI READ ELEMENT
STATUS command, which makes the 'chio status' command fail.

>How-To-Repeat:

chio status
