SYNOPSIS

10

DESCRIPTION

12       sg_rdac  displays  or  modifies  the  RDAC  controller settings via the
13       Redundant Controller mode page (0x2C). When modifying the  settings  it
14       allows  one  to transfer the ownership of individual drives to the con‐
15       troller the command was received on.
16

OPTIONS

18       -6     Use the 6 byte cdb variants of the  SCSI  MODE  SENSE  and  MODE
19              SELECT  commands.   The  default  action (in the absence of this
20              option) is to use the 10 byte cdb variants.
21
22       -a     Transfer all (visible) devices
23
24       -f=LUN Transfer the device identified by LUN. This  command  will  only
25              work   if  the  controller  supports  'Dual  Active  Mode'  (aka
26              active/active mode).  LUN  is  a  decimal  number  which  cannot
27              exceed  31  when  the  -6  option  is given, otherwise is cannot
28              exceed 255.
29
30       -v     be verbose
31
32       -V     print version string then exit
33
