阿里云更换 License 后无法增加 CPU

问题现象

1. 某用户将运行在云上的 FortiGate HA 两台虚机的 License 由评估 License 更换为正式 License，如 FortiGate-VM04 替换为 FortiGate-VM04-S。

2. 更换后，备机 VM 的 CPU 变为 1 个。

3. 无法通过exe cpu add添加 CPU。

   FGT-VM64-KVM-1502 # exe cpu add 3
   CPU number exceeds license limit.
   Command fail. Return code -61

解决办法

1. 将 FortiGate HA 主备切换后，在新主机（原备机）执行execute update-now手动触发更新，之后可以正常添加 CPU Core。

   FGT-VM64-KVM-1502 # exe update-now
   ......
   FGT-VM64-KVM-1502 # exe cpu add 3
   Active CPU number: 4
   Total CPU number: 4
   
   FGT-VM64-KVM-1502 # exe cpu show
   Active CPU number: 4
   Total CPU number: 4

2. 查看该 VM 相关参数均显示为新 License 的 CPU 信息。

   FGT-VM64-KVM-1502 # get system status
   ......
   Serial-Number: FGVMSLTM23007738
   License Status: Valid
   VM Resources: 4 CPU/4 allowed, 7735 MB RAM
