  • Storage subsystem and its logical unit processing method
    Patent number: 8539156
    Abstract: When a command to restore a logical unit is issued after a command to delete the logical unit, the logical unit is restored easily. When a controller receives an LU deletion command from a management terminal and if the relevant LU is a normal LU, it retains information about the deletion target LU, from among information in an LU management table, as reset information; and if the relevant LU is a virtual LU, the controller retains information about the deletion target LU, from among information in a virtual address table, as the reset information. If the controller receives an LU restoration command to restore the deletion target LU as an access target LU, from the management terminal, it restores the retained reset information as setting information corresponding to the access target LU and manages the restored setting information by using the LU management table or the virtual address table, thereby processing an access request from a host computer.
