SG_RDAC(8)                                    SG3_UTILS                                   SG_RDAC(8)



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  individ‐
       ual 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 de‐
              fault 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.
