  • Publication number: 20110099260
    Abstract: If both of LUN security information on storage apparatuses and configuration information on an iSNS server are acquirable, a management server makes reference to configuration situation of the LUN security acquired from a monitoring-target storage apparatus, thereby acquiring iSCSI initiator names which are permitted to access the storage apparatus. Moreover, the management server acquires, from the iSNS server, IP address of an iSCSI initiator name which does not exist on a monitoring-target host out of the iSCSI initiator names, then adding the IP address into monitoring-target nodes. Meanwhile, when an access from the management server to a monitoring-target node becomes impossible for a certain constant time-period due to a reason such that the monitoring-target node has been excluded from the network, the management server is capable of excluding the monitoring-target node from the monitoring targets on a GUI.

  • Publication number: 20100274883
    Abstract: Responsive to a manipulation a storage administrator performs, the authority to manage the physical configuration of a storage system is either given or not given to the storage administrator. Specifically, a volume allocation program installed in a management computer gives the storage administrator the authority to manage the physical configuration of a storage system including a created volume, responsive to creation of a volume. A volume un-allocation program installed in the management computer verifies responsive to un-allocation of a volume whether the storage administrator is not given the authority to manage the physical configuration of the storage system including the un-allocated volume. Thus, by use of the two programs, the storage administrator can manage both a physical configuration and a logical configuration exclusive of other storage administrators.
