|
|

default, the output is displayed one page at a time,
advanced by pressing the spacebar. The –no-page option enables a
continuous stream of output without page breaks.
|
|
listcurrenttid
|
Lists the current transaction ID.
|
|
commit [–tid
tid]
|
Commits the modified configuration to become the
active configuration.
|
|
abort [–tid
tid]
|
Abruptly ends the configuration session. All modified
configuration information is lost and the active
configuration remains unchanged.
|
|
where:
-
tid is the transaction ID
(0 to 4294967295).
-
partition_name is an alphanumeric tag
to the InfiniBand partition (optional).
-
p_key is the partition key
(1 to 7fff or
default).
Note -
You cannot delete the pre-defined partitions with P_Keys
1 and
7fff.
-
defmember is the default membership
type (full, limited, or
both) for the partition.
Note -
If ports are added to the partition without specifying the
membership type, the default membership type is applied to the
port.
-
mtu is the number that maps to the
actual MTU (1 to 5).

rate is the number that maps to the
actual throughput of a link (link width + link speed)
(2 to 10).

-
sl is the service level
(0 to 15).
Note -
Use service level 1 (sl 1) only for
low-latency, high-priority, small-message, low-bandwidth
traffic. Use other service levels for regular, high-bandwidth
traffic.
-
scope is the multicast address scope
value (1 to 14).
Note -
The mtu, rate,
sl, and scope
parameters are for the multicast group created when
ipoib (IP over InfiniBand) is configured
for the partition. Typically, these values are not specified as
the defaults are sufficient for the fabric configuration.
-
port is the GUID of the port, or the
special parameter, to add, remove, or modify:
-
ALL_CAS – All CAs in the
InfiniBand fabric.
-
ALL_SWITCHES – All
switches.
-
ALL_ROUTERS – All
routers.
-
member is the membership type
(full, limited, or
both) for the port.
Description
This hardware command is used to manage the InfiniBand partitions and is
available only on management controllers that are hosting the primary (or
master) Subnet Manager. There are two configurations for the InfiniBand
partition, the active configuration and the modified configuration. When
configuring a partition, you must initiate the configuration session with
the smpartition start command. During the session, you
create a modified copy of the active configuration. To end the session, you
must use the smpartition commit command to make the
modified configuration the active configuration. Once committed, the active
configuration is distributed to all Subnet Managers in the InfiniBand fabric
where the management controller's IP addresses are listed in the Subnet
Manager nodes file.
The Subnet Manager nodes file must exist in every management controller
file system. The file contains a list of IP addresses of all active
management controllers hosting a Subnet Manager in your fabric. The file
should have an entry for every Sun Datacenter InfiniBand Switch 36 and Sun
Network QDR InfiniBand Gateway Switch that runs a Subnet Manager in your
InfiniBand fabric.
Options
This table describes the options to the smpartition
command and their purposes.
|
|
|
–tid
|
Specifies the transaction ID. The transaction ID adds
an additional layer of security to the
smpartition command. The
identifier is a 32-bit unsigned integer, returned when
the partition configuration session is started with the
smpartition start tid command.
This identifier is then required for all subsequent
actions to the particular partition. Use of the
transaction ID mediates changes to the partition by
multiple users.
|
|
–n
|
Specifies the partition name.
|
|
–pkey
|
Specifies the partition key.
|
|
–use_grh
|
If the –use_grh option
is used in the smpartition create
command, a requirement of the partition is that Global
Route Headers (GRH) are attached to InfiniBand messages
and are used for path resolution requests made to the
Subnet Manager. This option provides additional security
for Engineered Systems.
|
|
–m
|
Specifies the membership type.
If the –m option is used in the
smpartition create command, the
default membership type of the partition is specified.
If the –m option is used with the
smpartition add command or
smpartition modify command, the
membership type of the port is specified.
If ports are added to the partition without specifying
the membership type, the default membership type for the
partition is applied to the port.
|
|
–port
|
Specifies the port or ports to be acted upon:
Alternatively, one these special parameters is
specified instead of a GUID.
-
ALL_CAS – All
CAs in the InfiniBand fabric.
-
ALL_SWITCHES –
All switches.
-
ALL_ROUTERS –
All routers.
|
|
–flag
|
Specifies:
-
ipoib – If present,
IP over InfiniBand is to be supported.
-
mtu – Sets the
MTU.
-
rate – Sets the
throughput of a link (link width + link
speed).
-
sl – Sets the service
level.
-
scope – Sets the
multicast address scope.
Note -
The –flag option by itself
disables IPoIB.
If you use the –flag option in the
smpartition modify command, you
must restart the master Subnet Manager or perform a
Subnet Manager handover after the smpartition
commit command. Because this causes an
interruption of service, if you want flag parameters
different than the default, consider setting partition
flags at the time of partition creation.
