Subcommand Options
- config -i HAINFO_FILENAME -s SMN_NAME
- Specifies high availability settings to be used to enable high availability between the primary management node and the secondary management node, where HAINFO_FILENAME is the high availability definition file and SMN_NAME is the name of the secondary management node.
- -i|--import HAINFO_FILENAME
- Specifies the import file name of the high availability definition file, where HAINFO_FILENAME is the name of the high availability definition file.
- -s|--secondary SMN_NAME
- Specifies the secondary management node name, where SMN_NAME is the name of the secondary management node.
