ここ最近Unity VSAを色々いじくり回してるんだけど、実は古い方のUnity VSAに問題が起きていて、プール一覧が全く表示できずに居る。実は検証の状況が変わり、ファイルシステムやLUNを削除した結果、全く使われてないプールが2つほどあるんだけど、GUI上からこれらを削除できずに居るという話で。やりたいこととしては

• 使われなくなったプールを削除したい
• 削除したぶんを活用してCIFS用のプールを増やしたい
• 増やしたCIFS用プールの領域を使ってファイルサーバとして使ってるファイルシステムの容量を拡張したい

というところ。

というわけで、仕方なくCLIを使ってこれらを実現することにしたのですよ。

• まず、UEMCLIをダウンロードする。(ダウンロードはEMCアカウントが必要ですよ)
• UEMCLIをインストールする。
  • インストール中、SSLを使うかどうかについて設定確認を求められるが、SSLを使う場合、証明書の組み込み等が必要になる。バッチスクリプト等の実行で恒久的に動かす場合、Low(SSL使わない)にしたほうが良い場合もあるので、業務用途に使う場合はちょっと考えたほうがいいかも。
• コマンドプロンプトでUEMCLIを実行する

取り敢えず、使われない2つのプールを削除するために、プール一覧を出力する。

あ、いらないプールは実際には3つほどあったのか。取り敢えずこれらを削除することにする。

これでプールを削除できた。どのプールにもバインドされてないディスクはVMware上の「設定の編集」で仮想ディスクを削除することにより、ディスクを外すことが可能となる。

ディスク外した後、必要容量を持ったディスクを再度作成し、装填する。その後、該当ディスクのTier設定を行い、プールに組み込めるようにする。搭載した仮想ディスクは、Tier設定をしないとプールに組み込めないので注意が必要である。

C:\WINDOWS\system32>uemcli -d 192.168.100.219 -u local/admin -p ******** /env/disk -id vdisk_14 set -tier performance
Storage system address: 192.168.100.219
Storage system port: 443
HTTPS connection

ID = vdisk_14
Operation completed successfully.

Tier設定後、既存プールにディスクを組み込んで、プール容量を拡張する。

C:\WINDOWS\system32>uemcli -d 192.168.100.219 -u local/admin -p ******** /stor/config/pool -id pool_3 extend -disk vdisk_14
Storage system address: 192.168.100.219
Storage system port: 443
HTTPS connection

Operation completed successfully.

容量は以下のようになりまして。

拡張前：Total space                                       = 2618051002368 (2.3T)

拡張後：Total space                                       = 2938562936832 (2.6T)

300GBほど容量拡張ができました。あとはGUIでファイルシステムの容量を300GB広げればOK。というわけで、無事に容量追加できました。よかったよかった。

なお、ファイルシステムは筐体間レプリケーションをしてるわけですが、相手方に対するファイルシステムの拡張は、レプリケーションをSyncさせた時点で自動的に相手方に対して反映されます。このあたりはVNXと同様の動きをしてくれるようですな。
