In one embodiment, a first VIOS receives an I/O request from the client LPAR. The first VIOS detects that a problem exists with a fabric connection to the block storage, and the first VIOS responds to the detected connection problem by autonomously propagating the I/O request to a second VIOS to which the first VIOS is connected. Forwarding of the I/O request to the block storage is subsequently completed by the second VIOS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Autonomous propagation of virtual input/output (VIO) operation(s) to second VIO server (VIOS) due to a detected error condition at a first VIOS","description":"A method provides input/output (I/O) redundancy within a data processing system having (a) a client logical partition (LPAR) that generates and consumes I/O requests, (b) a plurality of virtual input/","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8495412","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.
