6 ipmctl-show-region - Retrieves a list of persistent memory regions
7
9 ipmctl show [OPTIONS] -region [TARGETS]
10
12 Retrieves a list of persistent memory regions of DCPMM capacity
13
15 -a, -all
16 Shows all attributes.
17
18 Note
19 The all and display options are exclusive and may not be used
20 together.
21
22 -d (attributes), -display (attributes)
23 Filters the returned attributes by explicitly specifying a
24 comma-separated list of any of the attributes defined in the Return
25 Data section.
26
27 Note
28 The all and display options are exclusive and may not be used
29 together.
30
31 -h, -help
32 Displays help for the command.
33
34 -o (text|nvmxml), -output (text|nvmxml)
35 Changes the output format. One of: "text" (default) or "nvmxml".
36
37 -u (B|MB|MiB|GB|GiB|TB| TiB), -units (B|MB|MiB|GB|GiB|TB| TiB)
38 Changes the units that capacities are displayed in for this
39 command. One of: bytes (B), megabytes (MB), mebibytes (MiB),
40 gigabytes (GB), gibibytes (GiB), terabytes (TB) or tebibytes (TiB).
41
43 -region (RegionIDs)
44 Restricts output to specific persistent memory regions by providing
45 one or more comma separated region identifiers. The default is to
46 display the persistent memory regions across all manageable DCPMMs.
47
48 -socket (SocketIDs)
49 Restricts output to the persistent memory regions on specific
50 sockets by supplying the socket target and one or more
51 comma-separated socket identifiers. The default is to display all
52 sockets.
53
55 Shows all attributes of all persistent memory regions in the server.
56
57 ipmctl show -a -region
58
59 Shows all attributes for the specified persistent memory region.
60
61 ipmctl show -a -region 1
62
64 All the underlying DCPMMs should be unlocked to accurately reflect the
65 available capacities. The specified DCPMM(s) must be manageable by the
66 host software.
67
69 The default behavior is to display a table with the default attributes
70 listed below; applying options changes the output to a more detailed
71 format.
72
73 ISetID
74 (Default) The region unique identifier. Also known as interleave
75 set cookie.
76
77 PersistentMemoryType
78 (Default) A comma-separated list of the underlying type(s) of
79 persistent memory capacity in the region. One or more of:
80
81 · AppDirect: App Direct capacity interleaved across two or more
82 DCPMMs that is fully mapped into the system physical address
83 space.
84
85 · AppDirectNotInterleaved: App Direct capacity wholly contained
86 on a single DCPMMs that is fully mapped into the system
87 physical address space.
88
89 Capacity
90 (Default) Total usable capacity, both allocated and unallocated
91
92 FreeCapacity
93 (Default) Remaining usable capacity
94
95 SocketID
96 (Default) Socket ID to which the region belongs
97
98 HealthState
99 The rolled up health of the underlying DCPMMs. One of:
100
101 · Unknown: The region health cannot be determined.
102
103 · Healthy: All underlying DCPMM persistent memory capacity is
104 available.
105
106 · Pending: A new memory allocation goal has been created but not
107 applied. Reboot or delete any existing memory allocation goals
108 before creating namespaces on the region.
109
110 · Error: There is an issue with some or all of the underlying
111 DCPMM capacity because the interleave set has failed.
112
113 · Locked: One or more of the of the underlying DCPMMs are locked.
114
115 DimmID
116 A list of all the DIMMs that are part of this reg.
