Introduction to 11.5.1.13900-57-recovery.iso Software
This SHA-512 signed recovery ISO (4.3GB) enables full system restoration for Cisco MDS 9000 Series Multilayer Fabric Switches running NX-OS 11.5(1) software. Released through Cisco’s Storage Networking Software Center in Q3 2025, it addresses critical system failures requiring bare-metal recovery while maintaining FC-SP-2 security compliance for enterprise SAN environments.
The package supports Cisco MDS 9706 Directors and 9148S Fabric Switches, featuring embedded diagnostic tools for root cause analysis of firmware corruption incidents. It preserves Fibre Channel zoning configurations during restoration processes through integrated zone database migration utilities.
