Storage system, management host, method for restricting storage access, access restriction method performed by management host, and program for executing access restriction method

摘要

After a host creates a memory area in an external storage device, a setting is made such that the host can manage the memory area in the external storage device, so as to prevent an access to the storage device by another host to protect data therein. A second storage device creates a memory area therein, an iSNS server registers a lower DD between first and second storage devices, the first storage device makes a mapping-setting registration for names of a memory area for use and an external memory area, and the iSNS server registers an upper DD between the host and the first storage device, and the host mounts a memory area of the first storage device.
