Subsequent to detecting the change, first and second input/output (I/O) requests for the logical volume are received from a given host port, and a first unit attention message is conveyed to the given host port in response to the first I/O request. A second unit attention message is conveyed to the given host port upon determining that the storage system received the second I/O request within a specific time period commencing upon receiving the first I/O request. However, the second I/O request can be performed if the storage system received the second I/O request subsequent to the specific time period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Safely mapping and unmapping host SCSI volumes","description":"Methods, apparatus and computer program products implement embodiments of the present invention that include detecting, by a storage system, a change in a mapping of a logical volume to one or more ho","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9779003","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
