An NPIV client recovery component of a virtualization management component, such as a Power Hypervisor (pHYP), provides the emulation mapping between server and client virtual fibre channel adapters. The pHYP also provides a mechanism that prevents client partition crashes when the NPIV server (e.g., a VIOS logical partition) goes down. When the NPIV server is rebooted or powers down, the pHYP handles the client LPARs to avoid a crash by removing processing resources from the client logical partition. Thereby, the client logical partition is prevented from attempting to access a root volume group in physical storage via the NPIV server. The pHYP allocates processor resources to the client LPAR when the NPIV server is again available for I/O processing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mechanism for preventing client partition crashes by removing processing resources from the client logical partition when an NPIV server goes down","description":"With N_Port ID Virtualization (NPIV), a managed system can be configured so that multiple logical partitions (LPARs) can access independent physical storage through the same physical fibre channel ada","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8495217","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.
