実行中の Alpha コンピュータを Alpha 共通システム・ディスクに追加する操作や,実行中の VAX コンピュータを VAX 共通システム・ディスクに追加する操作を続行すると,最終的にディスクのストレージまたは I/O キャパシティが満杯になります。その場合,増加した負荷に対応するために 1 つ以上の共通システム・ディスクを追加できます。
メモ: システム・ディスクを VAX コンピュータと Alpha コンピュータの間で共用することはできません。Alpha システムを VAX システム・ディスクから作成することはできず, VAX システムを Alpha システム・ディスクから作成することもできません。

ボーツ・メンバの追加や削除,あるいはクォーラム・ディスクの有効化や無効化など,一部の構成機能では,1 つ以上の追加操作が必要です。
これらの操作は 表 8-10 に示すとおりであり,クラスタ全体の整合性に影響します。 CLUSTER_CONFIG_LAN.COM または CLUSTER_CONFIG.COM を実行して構成を大きく変更した後,実行しなければならない操作については,表の説明を参照してください。
クラスタ構成プロシージャを実行する目的 | 必要な後処理 | ||||||||
---|---|---|---|---|---|---|---|---|---|
ボーツ・メンバを追加または削除する。 | 第 8.6.1 項 の説明に従って,クラスタ内のすべてのノードの AUTOGEN パラメータ・ファイルと現在のシステム・パラメータ・ファイルを更新する。 | ||||||||
クォーラム・ディスクを有効にする。 | 以下の操作を実行する。
関連項目: クォーラム・ディスクの追加の詳細については, 第 8.2.4 項 も参照。 |
||||||||
クォーラム・ディスクを無効にする。 | 以下の操作を実行する。
警告: これらの操作は,OpenVMS Cluster システム全体をリブートできる状態になるまで実行してはならない。この操作ではクラスタのクォーラムが削減されるため,削除されるクォーラム・ディスクによって行われるボーツの結果,クラスタがパーティションに分割される可能性がある。
関連項目: クォーラム・ディスクの削除の詳細については, 第 8.3.2 項 も参照。 |
||||||||
サテライト・ノードを追加する。 | 以下の操作を実行する。
|
