Sets the readable M_Key for the Subnet Manager.
setsmmkey m_key|none|list
where m_key is a 12-digit hexadecimal number
This hardware command adds an extra layer of security to administering the Subnet Managers of the InfiniBand fabric. The Management Key (M_Key) is a 48-bit value that is used like a password to authorize access to the Subnet Manager Agent, thereby regulating control of the HCAs, switches, and other InfiniBand devices within the fabric. Any attempt to initialize or configure an InfiniBand node without the correct readable M_Key will fail.
The readable M_Key provides for two specific security features:
Any unauthorized host-based Subnet Manager cannot assume control of the InfiniBand fabric.
Prevents unauthorized modification of the Subnet Manager Agent from outside of the Subnet Manager.
The none and list arguments of the setsmmkey command disable the readable M_Key functionality or display the current readable M_Key value respectively.
Note - The same readable M_Key value must be configured on all Subnet Managers in the InfiniBand fabric. Additionally, you must disable the Subnet Manager before setting the readable M_Key value, and re-enable the Subnet Manager after setting the readable M_Key value.
Note - Once the readable M_Key is configured, the ibportstate command can no longer enable, disable, or reset a port. However, the enableswitchport and disableswitchport commands are still functional.
Note - Enabling secret M_Key functionality overrides any readable M_Key configured.
The setsmmkey command is available from the /SYS/Fabric_Mgmt Linux shell target of the Oracle ILOM CLI interface.
This example shows how to set the readable M_Key for the Subnet Manager with the setsmmkey command.
