LinuxにSCSIドライブを完全に無視させる方法は？

〜のようにこの問題私はドライブを完全に無視したいのですが、私の場合はシステムにSCSIドライブとして公開されています。私のサーバーの21台のドライブのうち2台が失敗しました。

私たちの場合、これは古いサーバーであり、アップグレード/修正しないことにしました。今、既存のドライブを取り外さずにそのままにして、アレイを縮小して無効にすることを検討しています。アレイがいっぱいになっていないため、他のサーバーの追加のバックアップ場所としてのみ使用してください。

だから私は怠惰でサーバールームに行きたくありません。このドライブを無効にして続行する方法はありますか？ :-)

答え1

非常に高いSCSIデバイス番号（scsi 0:0:90903:0）は、ハードウェアが絶えず欠落してドライブを再初期化する状況で問題があることを示します。

MPT SASハードウェアはここでほとんどの再初期化を実行するため、カーネルはそれを完全に制御できません。また、21台のドライブがあると言われました。したがって、1つ以上のSASエクスパンダの背後にある可能性があります。

問題は、ソフトウェアを介してSASエクスパンダのポートを無効にできるかどうかです。

エキスパンダーがこれをサポートしている場合（標準ではオプションだと思います）はい！

問題のパッケージはsmp_utils。sg3_utilsも役に立ちます）。

あなたが望むもの：

  1. 上記のマンページに従って拡張デバイスを見つけます（おそらくls /dev/bsg/expand*）。

  2. dmesgによる確認：障害のあるディスクがphyに接続されていることを確認してくださいsmp_discover /dev/bsg/expander-...。

  3. フォームでPHYを無効にします。smp_phy_control --phy=NN --op=di /dev/bsg/expander-...。あなたのケースに合わせて拡張されました。 smp_phy_control --phy=13 --op=di /dev/bsg/expander-0:0 smp_phy_control --phy=15 --op=di /dev/bsg/expander-0:0

phy番号はすでに出力にあります（13、、）。15ただし、を使用して確認する必要がありますsmp_discover。

あなたがやろうとしているのは、Oracleがブロックに直接アクセスするOracle ASMディスクの設定と同じように聞こえます。
