2.3.2 DESCRIPTION

COMMON USAGE The fsebak command affects core FSE components. It

should be used with a maximum care as its usage can lead to improper FSE system

operation or no operation at all. FSE administrator has to know exactly what he

is doing when using this command. fsebak is primarily meant to be used by the

FSE support personnel.

INTERNAL COMMAND OPERATION fsebak prepares Hierarchical Stor-

age Management Databases (HSMDBs) and File System Catalogs (FSCs) of all

conﬁgured FSE partitions for an eventual copying. To achieve database consis-

tency, operation of all currently running Partition Managers has to be temporarily

suspended. Duplicate copies of HSMDBs and FSCs can then be created using

other system commands. After copying Partition Managers are unblocked using

fsebak once again. This action restores the normal FSE system operation.

Each FSE command communicates with the FSE system components through the

Management Interface (fse–mif). To execute an FSE command, the Management

Interface must be running. If the connection to the Management Interface fails,

check its status by running the fse status command. In case the Management

Interface is not running, start it with the fse start command. Additionally, the
