ミラーディスク片系交換後、データ消失

ミラー構成のディスクで、片系のディスクを交換後、データが消失してしまいました。
手順のミスだったのか、原因教えて頂きたく、お願いします。
/dev/dsk/c6t0d0が交換したディスクです。
/dev/dsk/c4t0d0がミラーディスクです。

以下、実行コマンドです。

ミラーディスク片系交換後、データ消失

VxFS ファイルシステムじゃないって、メッセージがでてますから、LVMの不具合や手順のミス等で交換したディスクから同期が取られてしまったのか、元々故障時に壊れてしまっていたのか、どちらかなのですが、わかりませんね。

ディアクティベートされていたようですけれど、オンライン交換ができれば、もしかしたら何かわかったかもしれません。

http://docs.hp.com/en/oshpux11iv2.html#LVM%20Volume%20Manager

ここに、”When Good Disks Go Bad: Dealing with Disk Failures under LVM”というディスク故障にどう対応するかと言うマニュアルがあるのですが、結構11v3寄りの記述が多いです。また、パッチが色々紹介されていて、使っている環境にインストールされていない場合、有効ではない場合もあります。
ソフトウエアミラーの修理は、Know-Howもあるのでエンジニアに任せてしまった方がよい場合もあるとは思います。

良い情報ではなくてすみません。バックアップがあったと思いたいです。
