    Upgrade Procedure

    • Download image from https://software.cisco.com
    • Check Upgrade Preparation (next section)
    • Upload Image to ACI
      • Admin > Firmware > Firmware Repository
    • Create Firmware Group
      • Fabric Node Firmware > Firmware Groups
    • Create Maintenance Group
      • Fabric Node Firmware > Maintenance Groups
    • Perform APIC Upgrade
      • Controller Firmware
    • Perform Fabric Node Upgrade
      • Fabric Node Firmware > Maintenance Groups
    • Upgrade status check
      • From APIC "show firmware upgrade status"

     

    Upgrade Common Issues

    • CIMC
      • TPM may get disabled after CIMC upgrade
        • Upgrade from 2.0(3i) > 2.0(9c)
        • Bug ID: CSCvc93090
        • Workaround: Access BIOS and change TPM setting
      • Memory Leak
        • CIMC running earlier than 1.5(4g) or 2.0(3i)
        • Bug ID: CSCun88303
        • Workaround: Powercycle by un-plugging the power
        • Fix: Upgrade CIMC to 2.0(3i) and above
    • APIC
      • APIC does not start upgrade (IPMI Hang)
      • APIC2/3 stuck at 75%
        • APIC 1 stuck on upgrade
        • Bug ID: CSCuv45740
        • Workaround:
          • Access APIC1 via KVM as "rescue-user" using last known admin password
          • Perform "acidiag restart mgmt"
        • APIC 2/3 does not recognize APIC1 finished upgrade
        • Bug ID: CSCvb94260 (more common than above)
        • Workaround:
          • "acidiag avread" to check version timestamp on each APIC1 and APIC2/3
          • acidiag restart mgmt
