[21.03][Victoria][Ironic] "deploying"阶段'No suitable device was found for deployment'

【标题描述】baremetal node进入"deploying"阶段后，/var/log/ironic/ironic-conductor.log出现'No suitable device was found for deployment'报错
【环境信息】
硬件信息：
1） Ironic服务部署于清华同方超越E500-15170台式机,台式机为OpenStack ALL-in-one节点，用于测试Victoria Ironic。
    (intel i7-10700 2.9GHz; 16G DDR4 2666)
2） 裸金属目标机为清华同方服务器

软件信息(部署OpenStack服务物理机上的软件信息)：
1）	OS版本及分支:  openEuler 21.03
2）	内核信息:  5.10.0-4.17.0.28.oe1.x86_64
3）	发现问题的组件版本信息: OpenStack Victoria
【问题复现步骤】
**具体操作步骤**
参照 https://docs.openeuler.org/zh/docs/21.03/docs/thirdparty_migration/OpenStack-victoria.html 及 https://docs.openeuler.org/zh/docs/21.09/docs/thirdparty_migration/OpenStack-wallaby.html，在OpenEuler 21.03上部署OpenStack
All-in-one节点。（部署服务包括：Keystone、Glance、Placement、Nova、Neutron、Ironic）
因Ironic-inspector服务运行出现问题，希望首先走通流程，未纠结此。关闭inspector服务，回退相应配置。参照上述文档及OpenStack官方文档，手动设置硬件参数。裸金属服务只运行openstack-ironic-api.service和openstack-ironic-conductor.service。

设置硬件参数等配置操作如下
```shell
openstack baremetal node set $NODE_UUID \
    --property cpus=$CPU_COUNT \
    --property memory_mb=$RAM_MB \
    --property local_gb=$DISK_GB
openstack baremetal node set $NODE_UUID \
--property capabilities='boot_mode:bios'
# 此处因为未配置swift等,在测试环境中,使用iscsi部署接口,配置文件已对应配置(按自己目前理解,当前报错的点,还未走到此环节,未涉及user images的传输，deploy images运行就已出现无法找到磁盘的报错；如理解有误，希望社区的同学见谅，指点)
openstack baremetal --os-baremetal-api-version 1.31 node set $NODE_UUID \
    --deploy-interface iscsi \
    --raid-interface agent
```

配置好baremetal节点信息后
```shell
# Making node available for deployment
openstack baremetal --os-baremetal-api-version 1.11 node manage $NODE_UUID
# provide命令会自动执行clean，clean执行状态为success
openstack baremetal --os-baremetal-api-version 1.11 node provide $NODE_UUID

# 创建用于 Bare Metal 服务的 Flavor
openstack flavor create --ram $RAM_MB --vcpus $CPU_COUNT --disk $DISK_GB my-baremetal-flavor
openstack flavor set --property resources:CUSTOM_$CLASS_NAME=1 my-baremetal-flavor
openstack flavor set --property resources:VCPU=0 my-baremetal-flavor
openstack flavor set --property resources:MEMORY_MB=0 my-baremetal-flavor
openstack flavor set --property resources:DISK_GB=0 my-baremetal-flavor

net_id=687e31ee-72b5-469c-bcd8-e3e3e19c26a7
# create server boot disk from this image
image=004b2e75-4309-4ba0-8b40-c9624dd9c0e8
# 执行完下句后，进入deploying阶段，出现报错
openstack server create --flavor my-baremetal-flavor --nic net-id=$net_id --image $image testing
```

出现概率： 必现
【预期结果】
能够正常识别硬盘，完成裸金属部署。
【实际结果】
openstack-ironic-conductor日志如下
