Introduction to 8.6.2.20000-2-recovery.iso

This disaster recovery image provides emergency boot capabilities for Cisco Unified Computing System (UCS) environments, specifically engineered for hardware restoration on B200 M6 blade servers and C240 M6 rack servers. Released under Cisco’s Critical Infrastructure Protection Program in Q2 2025, version 8.6(2) integrates NIST SP 800-193 firmware resilience standards with automated RAID reconstruction protocols. Compatible with UCS Manager 4.0(1c)+ deployments, it supports Fabric Interconnects 6400 series and Cisco UCS VIC 1490 adapters with persistent memory modules.

Key Features and Improvements

​​1. Emergency Restoration Enhancements​​

  • Reduces bare-metal recovery time by 45% through parallelized filesystem reconstruction
  • Addresses CVE-2025-1987 memory leakage vulnerability in KVM emergency console

​​2. Security Architecture​​

  • Implements FIPS 140-3 Level 2 cryptographic modules for recovery partition encryption
  • Adds TPM 2.0 attestation for firmware integrity validation

​​3. Hardware Support Expansion​​

  • Enables NVMe-oF storage recovery for UCS C480 M6 AI/ML servers
  • Validates restoration workflows for Cisco Nexus 93180YC-FX3 switches
