PowerFlex 3.6：Red Hat OpenStack 组件部署暂停

情况说明

使用 Ansible 脚本部署新的 RHOSP 环境，从而安装新的 PowerFlex 3.6.x SDC。

neutron-cleanup 守护程序无法启动。故障时间与端口摆动功能事件相关。

影响

RHOSP 部署已暂停，必须重试才能继续。

未知

可以使用以下任一解决方法来解决暂停状态：

1. 请继续重试。
2. 在 PowerFlex 中注册 SDC 后，通过运行以下命令禁用端口摆动（作为自动化过程的一部分）。

禁用特定 SDC 的端口摆动：

 scli --set_performance_parameters --sdc_id  --tech --sdc_port_flap_feature_enabled 0

禁用所有 SDC 的端口摆动：

 scli --set_performance_parameters --all_sdc --tech --sdc_port_flap_feature_enabled 0

受影响的版本

PowerFlex 3.6 及更高版本
