【七転び八起き】PowerStore3.0でAnsibleを使うときの注意

PowerStore3.0でAnsibleを使おうとしてはまった話です。

七転び八起きなので結構余計なつまづきがありますが備忘録もかねてそのまま書きます。

 

問題：今まで使えていたYmlファイルがエラーで使えない・・・

TASK [Create multiple volumes] *************************************************

failed: [localhost] (item=1) => {"ansible_loop_var": "item", "changed": false, "error_code": 1, "item": 1, "msg": "Got error HTTP code: 400, Bad Request [{'messages': [{'code': '0xE04040020008', 'severity': 'Error', 'message_l10n': 'Unable to parse passed url.'}]}] while getting details of volume", "status_code": "400"}

 

原因：インストールしていたAnsible Collectionが古かった！　（最新版は1.6）

参考サイト：https://github.com/dell/ansible-powerstore　

/ansible_collections/dellemc/powerstore/MANIFEST.jsonにて確認すると以下で1.4でした。

MANIFEST.jsonからの抜粋＞

"collection_info": {

  "namespace": "dellemc",

  "name": "powerstore",

  "version": "1.4.0",

 

対応策：最新版のAnsible Collectionを入れる！　

参考サイト：https://github.com/dell/ansible-powersto

①ansible_collectionsのあるDirectory にて以下実行

 # pip install PyPowerStore

# ansible-galaxy collection install dellemc.powerstore -p ＜インストール場所＞

中略＞

All requested collections are already installed. If you want to reinstall them, consider using `--force`.　

⇒エラーが出た！

なので言う通りに--forceつけて再度実行

# ansible-galaxy collection install dellemc.powerstore -p /home/ayasaito --force

中略＞

Installing 'dellemc.powerstore:1.6.0' to '/home/ayasaito/ansible_collections/dellemc/powerstore'

dellemc.powerstore:1.6.0 was installed successfully　

⇒成功！

②テストYmlを実行したらまたエラー！PyPowerStore 1.5.0.0ではだめらしい・・・

TASK [Create multiple volumes] *************************************************

failed: [localhost] (item=1) => {"ansible_loop_var": "item", "changed": false, "item": 1, "msg": "PyPowerStore 1.5.0.0 is not supported by this module. Minimum supported version is : 1.7.0 "}

③PyPowerStore1.7を入れる。　（参考：https://github.com/dell/python-powerstore　）

# pip install PyPowerStore==1.7.0.0

Collecting PyPowerStore==1.7.0.0

③再びテストYmlを実行　

# ansible-playbook test.yml
