Isilon On-Cluster Analysis (IOCA)ツールは、実行中のPowerScale Clusterの正常性を分析し、アップグレードの計画を支援*します。
* IOCAは、アップグレード作業の準備としてアップグレード関連ドキュメントのレビューに代わるようには設計されていません。『OneFS Upgrade Planning and Process Guides』を参照してください。
IOCAツールの最新リリースは、Lightningからダウンロードできます。
メモ: ダウンロードの日付が古い場合でも、最新リリースがダウンロードされます。
メモ: ダウンロードしてクラスターに転送したら、次のコマンドを使用してIOCAとIOCA.sha256を解凍する必要があります：
# tar -xvf IOCA.tar IOCA IOCA.sha256
IOCAの整合性を検証するには、前掲のtarパッケージ内のSHA256ファイルを使用するか、またはダウンロード用にここにホストされている独立したIOCA.SHA256ファイルを使用することができます。
ダウンロードしたら、IOCAスクリプトと同じ場所に転送します（既存のIOCA.SHA256を必ず上書きしてください）。
sha256sumを使用する場合：
# sha256sum -c /home/nyhanj1/IOCA.sha256 ./IOCA: OK
前掲の太字の結果を観察し、問題がないことを確認します。
sha256sumがない場合：
# cat IOCA.sha256 a55c9efcea29776317d3b3ed36c504dcab08d1f945161f6ac6c8bbb315f31bb0 ./IOCA
# sha256 IOCA SHA256 (IOCA) = a55c9efcea29776317d3b3ed36c504dcab08d1f945161f6ac6c8bbb315f31bb0
両方のチェックサムが一致することを手動で確認します。
isi_for_array cat /etc/isilon_serial_number
mkdir -pv /ifs/data/Isilon_Support
cd /ifs/data/Isilon_Support
IOCAの最新バージョンをクラスター上の/ifs/data/Isilon_Support/ディレクトリーにステージングします。
perl IOCA -v引数を追加して、IOCAツールを実行します。次の例には、アップグレード前チェックに9.5.1.0へのアップグレードのチェックが含まれ、ヘルス チェックの結果の後にアップグレード計画の推奨事項が表示されます。
perl IOCA -u 9.5.1.0
BMC/CMC Hardware Monitoring FAIL
FAIL: Hardware monitoring issues detected on nodes: 2
INFO: 3 nodes have out of date CMC firmware versions: 1-3
INFO: Refer to KB489050 (https://support.emc.com/kb/489050) for details.
この例では、ハードウェア モニタリングの問題があるノード2の障害を示しています。また、ノード1～3のCMCファームウェア バージョンが古いことを示す情報も含まれています。最後に、解決手順を含むKB記事が含まれています。
IOCAは、非コンプライアンス モード クラスターと同じ方法で、コンプライアンス モードが有効になっているクラスターで実行されます。sudoで実行する必要はありません。ただし、compadminユーザーがIOCAスクリプトを実行するには、その所有者である必要があります。
