Note - Unless the system has a redundant configuration, data on the hard disk drive will be
lost. Thus, perform this operation only after backing up the data on the hard disk drive. In
addition, active/hot maintenance of the boot device cannot be performed in a non-redundant
configuration.
Before performing maintenance, check the hardware configuration and software
configuration. For details, see
