DESCRIPTION The setupfru(8) command makes hardware settings for the specified device.
Only a physical system board (PSB) can be specified as a device. After a PSB is
added, the following settings can be specified for PSB:
Privileges You must have platadm or fieldeng privileges to run this command.
Refer to setprivileges(8) for more information.
OPTIONS The following options are supported:
XSB type To use an added PSB in the system, hardware resources
on the PSB must be logically divided and reconfigured as
eXtended System Boards (XSBs). Two types of XSB are
used: Uni-XSB and Quad-XSB. The Uni-XSB is configured
with undivided PSB, and the Quad-XSB is configured
with one of divided PSB into four parts. Specify either the
Uni-XSB configuration or Quad-XSB configuration for the
PSB.
Memory mirror mode In mirror mode, data is mirrored by dividing the memory
mounted on a PSB into two parts. Since the memory is
divided into two parts, the memory capacity is halved,
but data reliability increases. Specify whether to operate
the memory in mirror mode.
-h Displays usage statement. When used with other options or
operands, an error occurs.
-m {y|n} Specifies whether to use the memory mounted on the XSB in
mirror mode. Specify this option when sb is specified for device.
Specify y to enable mirror mode; otherwise, specify n. If the -m
option is omitted, the previous setting is inherited.
-x {1|4} Specifies whether to configure PSB as a Uni-XSB or Quad-XSB.
Specify this option when sb is specified for device. Specify 1 for
Uni-XSB or specify 4 for Quad-XSB. If the -x option is omitted,
the previous setting is inherited.
