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.
7.1.2 System Parameters
System parameters are necessary to start the subsystem (from turning on the main switch to
generation of the READY LED (green). 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.
