Understanding how P_Keys are Saved

Partition information is saved persistently by the master subnet manager. P_key information can be
synchronized between the master subnet manager and a slave subnet manager. The synchronization of
the subnet mangers means that the partition configuration (as well as other information) is exchanged
between the active and standby subnet managers. Therefore, the partition configuration will be
transferred in the event that an InfiniBand should fail.
The partition configuration is not saved persistently on a slave subnet manager.
If you have more than one InfiniBand switch in your fabric, refer to
Synchronization" on page
If you are configuring one InfiniBand switch, it will automatically be the master, and the partition
configuration is saved persistently on the switch.
Partitions are described in detail in
