Sets the default pkey for the BridgeX Manager.
where p_key is the partition key (1 – 7fff or default).
This hardware command changes the default PKey used by the BridgeX Manager to control traffic. By default, hosts are configured with the PKey default. If a different discovery PKey value is configured with the setdefaultgwdiscpkey command for the BridgeX Manager, hosts using the gateway resources must be configured with identical discovery PKeys, otherwise the VNICs will not become active. This condition requires the /etc/modprobe.conf file on a Linux host to be edited, where the options for the mlx4_vnic driver is to use discovery Pkeys. The entry into the /etc/modprobe.conf file would have this format:
options mlx4_vnic discovery_pkeys=comma_delimited_list_of_pkeys
options mlx4_vnic discovery_pkeys=0xffff,0xfff1,0x3
Note - If you have used the setdefaultgwdiscpkey command before creating a LAG, after creating the LAG, you must use the setdefaultgwdiscpkey command again to force the LAG to use the PKey.
The setdefaultgwdiscpkey command is available from the /SYS/Gateway_Mgmt and /SYS/Fabric_Mgmt Linux shell targets of the Oracle ILOM CLI interface.
This example shows how to set the default gateway discovery PKey with the setdefaultgwdiscpkey command.
