Monitoring-target-apparatus management system, management server, and monitoring-target-apparatus management method

A management server which is an apparatus for managing storage apparatuses and host apparatuses,

• wherein said storage apparatuses and said host apparatuses being coupled to each other via a network, said storage apparatuses which have volumes that are memory areas, said host apparatuses which use said volumes of said storage apparatuses via iSCSI (:
• Internet Small Computer System Interface) protocol,
• said management server comprising:
• a processor;
• and
• a memory storing an apparatus discovery program, information acquisition program, and a monitoring-target program,
• wherein said apparatus discovery program makes said processor to:
• make reference to discovery target address management information memorized in a memory unit and describing IP addresses of discovery targets;
• issue a transmission instruction for constitution information on said apparatuses with respect to said IP addresses of said discovery targets, and, if a response is given to said transmission instruction;
• and
• memorize, as said apparatus of said monitoring target, said IP address of an apparatus which has returned said response into discovered apparatus management information of said memory,
• wherein said information acquisition program makes said processor to:
• acquire constitution information on said apparatus of said monitoring target;
• and
• memorize said constitution information into device-coupling management information of said memory unit in such a manner that iSCSI target names coupled to said volumes, iSCSI initiator names permitted to access said volumes, and coupling-destination host IDs corresponding to said iSCSI target names are made related with each other, and
• wherein said monitoring-target program makes said processor to:
• make reference to said device-coupling management information if an iSNS (:
• Internet Storage Name Service) server has been registered into said discovered apparatus management information, and detect a volume for which said coupling-destination host corresponding to said iSCSI target name is unknown;
• acquire an access-permitted iSCSI initiator name corresponding to said volume for which said coupling-destination host is unknown;
• request said registered iSNS server to acquire said IP address corresponding thereto;
• and
• memorize said acquired IP address into said discovery target address management information and said discovered apparatus management information.

A monitoring-target-apparatus management method for detecting an apparatus coupled to a network, and monitoring said detected apparatus as said apparatus of a monitoring target,

• wherein said monitoring-target-apparatus management method being implemented in an information processing system where storage apparatuses, host apparatuses, and a management server are coupled to each other via said network, said storage apparatuses which have volumes that are memory areas, said host apparatuses which use said volumes of said storage apparatuses via iSCSI (:
• Internet Small Computer System Interface) protocol, said management server for managing said storage apparatuses and said host apparatuses, wherein
• said management server, comprising and executing:
• an apparatus discover step of
• making reference to discovery target address management information memorized in a memory unit and describing IP addresses of discovery targets,
• issuing a transmission instruction for constitution information on said apparatuses with respect to said IP addresses of said discovery targets, and, if a response is given to said transmission instruction,
• memorizing, as said apparatus of said monitoring target, said IP address of an apparatus which has returned said response into discovered apparatus management information of said memory unit;
• an information acquisition step of
• acquiring constitution information on said apparatus of said monitoring target, and
• memorizing said constitution information into device-coupling management information of said memory unit in such a manner that iSCSI target names coupled to said volumes, iSCSI initiator names permitted to access said volumes, and coupling-destination host IDs corresponding to said iSCSI target names are made related with each other;
• and
• a monitoring-target control step of
• making reference to said device-coupling management information if an iSNS (:
• Internet Storage Name Service) server has been registered into said discovered apparatus management information, and detecting a volume for which said coupling-destination host corresponding to said iSCSI target name is unknown,
• acquiring an access-permitted iSCSI initiator name corresponding to said volume for which said coupling-destination host is unknown,
• requesting said registered iSNS server to acquire said IP address corresponding thereto, and
• memorizing said acquired IP address into said discovery target address management information and said discovered apparatus management information.
