摘要：
A storage system which has flash memories constituting a storage area and a function of placing and handling the flash memories in on-line mode and off-line mode, and which stores and manages management information of the flash memories in on-line mode. The storage system includes: when some or all of flash memory in on-line mode is placed in off-line mode, creating a management area in off-line mode in the flash memories by moving existing data in an area used as the management area to an area other than the management area; writing the management information of the flash memories to the created management area; and placing the flash memories in off-line mode.
