memory info
The memory info command displays basic information on various
aspects of the host memory system, as described in the command options.
Command Syntax
udiag memory info { freespace | maxblock | dimms | dimm
<address> }
Options
|
|
|
freespace
|
Displays available memory for UEFI applications as
reported by BIOS.
|
|
maxblock
|
Displays the starting address and size for the largest
contiguous block available for UEFI applications.
|
|
dimms
|
Displays installed DIMM information at each CPU socket.
This is not available on systems equipped with Oracle ILOM
3.2.4 or newer.
|
|
dimm [x]
<address>
|
Translates the system
<address> into a physical
location in terms socket, channel, DIMM, rank, and chip
numbers. If x is present, then it uses the MP translator (if
available) instead of the default BIOS-provided
translator..
|
|
addr DRAM_INFO
|
DRAM_INFO := <socket> <mc> <channel> <dimm>
[<rank> [<bank> [<row> [<col>]]]]
Translates the DRAM information to the physical address
-
<socket> is the CPU
socket number (base 0).
-
<mc> is the memory
controller. For example on a two-socket system it is
0 or 1.
-
<channel> is the
channel on the memory controller. For example, it is
0 for processor 0, CH 0, and it is 3 for processor
1, CH 1.
-
<dimm> is the DIMM
slot number.
-
Optional DRAM
<rank>,
<bank>,
<row>, and
<col> all default to
0.
|
|
map [<address> |
RANK]
|
Displays system address mapping using DIMM ranks and
address ranges.
-
<address> displays
the address range info that
<address> belongs
to.
-
RANK = <socket>
<mc>
<channel>
<dimm> [<rank>]
-
<rank> is optional
and if absent, ranks are enumerated for
display.
