7.1 Software Composition
This section includes the following:
Microprogram
System parameters
Configuration information
SNMP information
Storage for parameters
7.1.1 Microprogram
A microprogram controls basic hardware operations which accompany the execution of given
instructions performed by a CPU. The version of the microprogram is controlled by the
following numerical format: xxxxx/xx.
The microprogram 07xxx/xx (x is optional), is available. However, /x may not be included in
the microprogram version number or another control system may control the microprograms.
NAS model has NAS OS and BIOS. NAS OS controls file service and NAS management function.
The version is managed by the following numerical format: xx-xx-xx (x is optional).
BIOS controls RKNAS initialization and NAS unit full memory dump (hereinafter referred to as
NAS dump) collection function. The version is managed by the following numerical format:
xxxxxxxx (x is optional).
7.1.2 System Parameters
System parameters are necessary to start the subsystem (from turning on the main switch of
RKS to generation of the RDY LED (green) of RKS. System parameters are stored in flash
memory. They can be backed up to a disk drive. When the system parameter changes, make
a backup copy on the disk drive.
7.1.3 Configuration Information
The configuration information is a record of customer data on the subsystem, such as the
RAID configuration and LU capacity. The configuration information exists in the disk drive
when the main switch is turned off; it is transmitted onto the main memory of the controller
when the main switch is turned on. When configuration information is changed, the
information on the disk drive is updated simultaneously.
7.1.4 SNMP Information
The SNMP parameter enables the SNMP function to operate effectively. When SNMP
information activates the SNMP function, the template contained in the SNMP information
(in the SNMP directory on the provided CD-R) is edited and registered in the subsystem.
