ディスクに取得したAIXのmksysbファイルから、bootableなDVDメディアを作成

Posted at

ディスクに取得したAIXのmksysbファイル(システムバックアップ)から、bootableなDVDメディアを作成してみました。

mksysbファイルを作成した後で、bootableなDVDメディアを作成できるとは思っていたけれど、自分でやるのは初めてだったので、"はじめてのおつかい" 気分です。

参考にしたマニュアルはこちらです。
ISO9660 フォーマットによる CD または DVD のルート・ボリューム・グループ・バックアップの作成:
https://www.ibm.com/docs/ja/aix/7.3?topic=csbcrdrdr-creating-root-volume-group-backup-cd-dvd-iso9660-format

少し試行錯誤がありましたが、結果として分かった環境に関する注意点は以下の部分のみでした。

IBM DVDドライブを使用する場合の注意覚え書き:
IBM スタンドアロンDVDドライブ (#EUA5)を使用する場合、DVD-RAMメディアが必要でした。
複数種のDVD-RやDVD-RWメディアも試しましたが、上手くいったのはDVD-RAMメディアのみ。
しばらく試行錯誤してから気がついたのですが、以下のREADMEに記述がありました。
IBM DVD Drive(#EUA5) を使用する場合は、READMEを読みましょう。
/usr/lpp/bos.sysmgt/mkcd.README.txt

What you'll need - other than your machine

You'll need a recordable CD drive (CD-R or CD-RW) or DVD drive (DVD-RAM).
Note: We currently test using 5X speed DVD-RAM media in IBM DVD-RAM drives.
Additionally, the IBM DVD-RAM drives only support writing to DVD-RAM
media (cannot write to DVD-R/RW, DVD+R/RW or CD media).

環境説明

環境は以下の通りです。
この環境では意図的に、roovgに /workを作成し、そこに100MBのファイルを60個配置しているので、mksysbファイルサイズも大きくなります。
また、 bkupvgに /bkupを作成し、そこにシステムバックアップ(mksysbファイル)を取得することにしました。

  • Power9 S914
  • AIX 7.3 TL2 SP2
  • IBM DVD Drive (機構番号:#EUA5)
  • 松下電器産業 DVD-RAM4.7GB(120分)カートリッジタイプ3枚パック LM-AB120LS3
    • アマ◯ンで3枚1,000円で買ってみました。
    • 届いてからカートリッジタイプだったことに気づき(汗)、カートリッジの中からディスクを抜いて使用しました。

以上でリストアができました。

あとがき

今回意図的に大きなmksysbファイルにしていて、mksysbファイルは約8GB、そのmksysbファイルからbootableなDVDを作成するのに約80分ほどかかりました。
新規AIXを導入(Server/App/CDEバンドル含む)しただけのrootvgであれば、2GB以下のmksysbファイルで、bootable DVDの作成も20分くらいで終わりました。
何かの参考になれば幸いです。
