The hadbm startnode command has one special option, --startlevel (short form -l), that specifies the level at which to start the node.
Node start levels are:
normal (default): starts the node with the data found locally on the node (in the memory and in the data device file on the disk) and synchronizes it with the mirror for recent updates it missed.
repair: forces the node to discard local data and copy it from its mirror.
clear: reinitializes the devices for the node and forces a repair of data from its mirror node. Use when the device files need to be initialized, necessary if they are damaged or the disk that contained the device files is replaced.
See General Options for a description of other command options.
