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 one 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).  LUN is a decimal
              number which cannot exceed 31 when the -6 option  is  given,  otherwise  is  cannot
              exceed 255.

       -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.
