LU パスを有効にする方法

LU へのパスが無効な場合、enable コマンドによってパスは元の有効な状態に変更されます。イニシエータポート名、ターゲットポート名、および LU を使用して、完全なパスを指定する必要があります。変更を確認するには、論理ユニットに対して show コマンドを実行します。

1. マルチパス化された LU のリストを表示します。

   # mpathadm list lu
           /dev/rdsk/c0t600144F08069703400004E828EE10004d0s2

3. LU パスを有効にします。

   # mpathadm enable path -i 210000e08b841feb -t 200900a0b826d63b \ 
              -l /dev/rdsk/c0t600A0B800026D63A0000A4984E234298d0s2
