MPCBL0050—Hardware Management
Description
This command allows the presence,
disabled, failure, and spared state of a
set of DIMMs to be obtained without
having to know the IPMC IPMI sensor
numbers of the associated DIMM
sensors. The state is returned as
bitmaps. A bit being set in a bitmap
indicates assertion of the state.
The DIMM that a bit offset refers to is
platform dependent. The DIMM Group
Selector value is platform dependent.
Platforms with 8 or fewer DIMMs
should always use 0 as the Group
Selector value. On platforms with
memory boards, the Group Selector
maps to a board number which is 1
based.
This command allows the failure state
of a set of DIMMs to be set. Executing
this command causes the associated
sensor offsets for affected DIMM
sensors.
The DIMM Group Id is defined the
same as for the Get DIMM State
command. The IPMC will accept a
variable number of request bytes: as
few as 1 bytes of this command (Group
selector) up to the fully defined set.
Note that the Group/Board Presence
flag is ignored on platforms that don't
implement removable groups (memory
boards).
Example of the Slot Existence bitmap:
Byte 2 = 0Fh and byte 6 = 0Dh means
DIMM 1,3 and 4 are present, the DIMM
2 slot is empty. DIMM slots 5,6,7 and 8
do not exist on this platform.
This command causes the DIMM failure
and disabled state of all DIMM sensors
to be reset.
