はじめに
NetApp StorageであるAFFではAdvanced Disk Partitioning（ADP）v2という機能を使ってActive-Activeのストレージノード（ストレージコントローラ）が高い性能を発揮できるように工夫がされています。
性能面では工場出荷時の状態でストレージノードごとに一つずつ、合計2つのAggregateを作成する方がベターですが運用利便性を考えて1つのAggregateとして運用したい場合があるかと思います。
本記事ではこの場合の1Aggregateにまとめる手順を記載しております。
なおこの手順はSystem Manager（GUI）で対応していないためCLIを用いて行います。
ADP（v1、v2）のルールや制約については以下のKBを参考にしてください。
何ができる？
- NetApp AFFシリーズのADP2環境でData1パーティションとData2パーティションを一つのAggregateとして作成
既存のAggregateにパーティションやディスクを追加する場合はSpareの状態である必要があります。利用予定のパーティション、ディスクで既にAggregateを作成済みの場合は事前に削除する必要があります
Aggregateへのパーティション、ディスクなどの追加作業はシステムへの影響なくオンラインで実施可能です
ADPv2でdata1パーティションとdata2パーティションを同一RaidGroupにする事はできません。別のRaidGroupとして同一Aggregateに追加する事が可能です。
設定手順
以下のステップで作業を実施します。
- 所有権情報の確認
- 権限レベルをadvancedに変更
- 所有権の変更
- 既存Aggregateへの追加シミュレーション
- 既存Aggregateへの追加
所有権情報の確認
::> storage disk show -disk <disk_name> -partition-ownership
権限レベルをadvancedに変更
set -privilege advanced
所有権の変更
工場出荷時にデフォルトでいずれかのノードが所有者となっているためほとんどの場合-forceオプションが必要となります。
data1パーティションの操作は-data1、data2パーティションの操作は-data2オプションを利用します。
data3パーティションはシステム領域となるため所有者を変更する事はできず必要もありません。
::> storage disk assign -disk <disk_name> -owner <owner_name> -data1 true -force true
既存Aggregateへの追加シミュレーション
::> aggregate add-disks -aggregate <aggregate_name> -diskcount <disk数> -simulate true
既存Aggregateへの追加
::> aggregate add-disks -aggregate <aggregate_name> -diskcount <disk数>
実行サンプル
C250 15.3TB SSDが10本搭載されたADPv2の環境でData1パーティションのOwnerをcluster-02に変更しcluster_02_SSD_CAP_1 Aggregateにパーティションを追加した際のログ
##diagユーザーに権限変更

##現在のパーティション情報を確認（記事の手順と違いdiag権限で実行可能なコマンドで確認を実施しています）
##記事の手順通りadminユーザー権限で以下コマンドを実行した場合でも類似の情報が得られます
##storage disk show -disk * -partition-ownership
