NAME
       sg_rdac - display or modify SCSI RDAC Redundant Controller mode page

SYNOPSIS
       sg_rdac [-6] [-a] [-f=LUN] [-v] [-V] DEVICE

DESCRIPTION
       sg_rdac  displays  or  modifies  the  RDAC  controller settings via the
       Redundant Controller mode page (0x2C). When modifying the  settings  it
       allows to transfer the ownership of individual drives to the controller
       the command was received on.

OPTIONS
       -6     Use the 6 byte cdb variants of the  SCSI  MODE  SENSE  and  MODE
              SELECT  commands.   The  default  action (in the absence of this
              option) is to use the 10 byte cdb variants.

       -a     Transfer all (visible) devices

       -f=LUN Transfer the device identified by LUN. This  command  will  only
              work   if  the  controller  supports  'Dual  Active  Mode'  (aka
              active/active mode).

       -v     be verbose

       -V     print version string then exit

EXIT STATUS
       The exit status of sg_rdac is 0 when it is  successful.  Otherwise  see
       the sg3_utils(8) man page.
