はじめに

Power Systems の RMC 通信 (HMC が管理用通信)では、Linux では IBM Power Systems service and productivity tools の ibm-power-managed パッケージの導入が必要になります。
RMC通信は、リソースの動的変更(Dynamic Logical Partition (DLPAR))、稼働中 VM の筐体間移動(Live Partition Mobility(LPM))などに必要です。

ibm-power-managed が導入されていない場合では、HMC が VM に管理のための通信ができないため、以下のように、VM の Health で接続されていないことを示す Warning 状態となります。

なお、AIX では最初から導入されているので別途導入の必要はありません。

当記事は RHEL 8.4 に ibm-power-managed パッケージを導入したログです。

環境

HW : PowerSystems S824
OS : RHEL 8.4 (ppc64le)　　（オフライン = インターネット非接続)

-> 11 の rpm が導入されました。ibm-power-managed のリポジトリ内モジュールの他、BaseOS から mksh が導入されています。

確認

導入から数分後、PowerVC 上で対象サーバーの Health が OK となっていることを確認しました。

これで RHEL サーバーも RMC 通信がつながり、DLPAR や LPM 操作が可能な状態になりました。

以上です。
