ib sm db-sync
To configure the database synchronize feature between the master subnet manager and one or more
standby (slave) subnet managers, enter the ib sm db-sync command in Global Configuration mode. To
disable database synchronization features, use the no form of this command.
Note
With database sync enabled on all chassis, only the chassis running the master SM will accept partition
configuration from the user.

Specifies the subnet prefix of the IB subnet on which you want to configure
performance monitoring.
Subnet prefix of the IB subnet on which you want to configure performance
monitoring
Enables database synchronization on your IB fabric.
Specifies the maximum number of backup subnet managers that will
synchronize with the master SM.
Note
Maximum number of backup subnet managers that will synchronize with
the master SM. This value defaults to 1.
Specifies the interval, in seconds, during which a synchronization session
status MAD packet must arrive at the master SM to maintain
synchronization. This value should be greater than the poll-interval value.
Timeout interval, in seconds. This value defaults to 10 seconds.
Interval at which the master SM polls an active slave SM to verify
synchronization.
Poll interval, in seconds. This value defaults to 3 seconds.
Allots a maximum amount of time in which to perform a cold sync. During
the cold sync, the master SM copies all out-of-sync tables to the standby.
Cold sync interval, in seconds. This value defaults to 10 seconds.
Specifies the maximum number of cold syncs that may take place during the
cold sync period. This value defaults to 2.
Maximum number of cold syncs per cold sync period (integer).
Specifies the length of the interval during which cold syncs may occur.
Duration, in seconds, of the cold sync period. This value defaults to 900
seconds.
Although we offer this configuration option, the master SM
currently only supports one standby.
