You can modify the partition’s configuration or the port(s) membership with the smpartition modify command.
# smpartition start #
# smpartition modify -n partition_name|-pkey p_key[-flag [ipoib, mtu mtu, rate rate, sl sl, scope scope]]|[-port port|ALL|ALL_CAS|ALL_SWITCHES|ALL_ROUTERS|SELF [-m member]
partition_name is the identifier of the InfiniBand partition.
p_key is the partition key (1 – 7fff).
mtu is the value of the MTU.
rate is the throughput of a link (link width + link speed) in Gbps from 2.5, 5, 10, 20, 30 to a maximum of 40.
sl is the service level.
scope is the multicast address scope value (0 – F).
Note - The mtu, rate, sl, and scope parameters are for the multicast group created when ipoib (IP over InfiniBand) is configured for the partition.
port is the GUID of the port, or the special parameter, to modify:
ALL – All of the CAs, switches, and routers in the InfiniBand fabric.
ALL_CAS – All CAs in the InfiniBand fabric.
ALL_SWITCHES – All switches.
ALL_ROUTERS – All routers.
SELF – The Master Subnet Manager.
member is the membership type (full, limited, or both) for the port.
For example, to configure the default partition for limited membership for CAs and no IP over InfiniBand support:
# smpartition modify -pkey 0x7fff -port ALL_CAS -flag -m limited #
# smpartition list modified # Sun DCS IB partition config file # This file is generated, do not edit #! version_number : 13 Default=0x7fff, ipoib : ALL_CAS=full, ALL_SWITCHES=full, SELF=full; SUN_DCS=0x0001, ipoib : ALL_SWITCHES=full; testpartition = 0x0005,defmember=full,ipoib: 0x00212800013e9313, 0x00212800013e93f7; #
