環境

  • Active IQ Unified Manager 9.18P3 (AIQUM)
  • Cloud Agent を介した REST ベースの取得
  • ONTAP MetroCluster
  • FabricPool またはアグリゲートオブジェクトストアの構成

問題

  • AIQUMは、1つまたは両方のMetroClusterクラスタの取得に失敗します。
  • ベースライン収集が完了したあと、Gモード変換が失敗します。
  • au.logに次のシグネチャが記録されます:
GModeAggregateObjectstoreConfigMapping - can't find aggregate uuid <partner_aggregate_uuid> on cluster name <cluster_name>

GClusterBuilder - ExecutionException encountered on Builder
java.util.concurrent.ExecutionException:
java.lang.NullPointerException:
Cannot invoke "java.lang.Comparable.compareTo(Object)" because "k1" is null

    at java.util.TreeMap.compare(TreeMap.java:1569)
    at java.util.TreeMap.addEntryToEmptyMap(TreeMap.java:776)

    at com.onaro.sanscreen.acquisition.datasource.netapp_ocie.builders.rest.gmode.netappfoundation.GAggregateBuilder.buildModel(GAggregateBuilder.java:221)

NetAppOCIEDataSource - GMode Conversion exception:
0 out of 1 devices acquired successfully.

アグリゲートの処理順序によっては、NPEは代わりに次のように始まる可能性があります:

java.lang.NullPointerException
    at java.util.Objects.requireNonNull(Objects.java:209)
    at java.util.TreeMap.put(TreeMap.java:809)
