HDDに使用している電源ケーブルの不良で稼働中にHDDの電源が落ちてしまい、
自動では復旧してくれなかったので手動修正することにします。
先ずは下記コマンドで全体の状況を確認してみます。（長いので一部のみ記載します）

この段階で確認出来るのが、
DG0、Arr0、Row7のDiskがFailed
RAID5構成のVirtual DrivesがDegraded
Enclosure Device ID 252番、Slotが7番がUnconfigured Bad
このDiskが完全にお亡くなり（というか途中でRAIDから外れてしまっただけ）ということですね。
私の方では、SNで搭載HDDを管理しているのでDiskSerialを確認します。
[root@nas GomenneGomenne-]# storcli /c0/e252/s7 show all Drive /c0/e252/s7 Device attributes : =================================== SN = ******** ←ここにSNが出ます Manufacturer Id = ATA Model Number = TOSHIBA DT01ACA200 NAND Vendor = NA WWN = ******** Firmware Revision = MX4OABB0 Raw size = 1.819 TB [0xe8e088b0 Sectors] Coerced size = 1.818 TB [0xe8d00000 Sectors] Non Coerced size = 1.818 TB [0xe8d088b0 Sectors] Device Speed = 6.0Gb/s Link Speed = 6.0Gb/s NCQ setting = N/A Write cache = N/A Sector Size = 512B
元に戻したいHDDである事を再確認しました。（それ以外には無いんですけどね。複数アレイ作業時には重要に・・・）
では早速戻していきます。
まず、UBad となっているHDDをUGoodへ変更し、異常が無いDiskとしてフラグを立てます。
[root@nas GomenneGomenne-]# storcli /c0/e252/s7 set good Controller = 0 Status = Success Description = Set Drive Good Succeeded.

次はRAIDから外れてしまったこのHDDをRAIDアレイへぶち込みます。
/c0/e252/s7 で対象のDiskを名指しします。
そして、DG0、Arr0、Row7のDiskがFailedになってる（何もアサインされてない）状態なので、この場所へDiskをInsertします。
ヘルプを見ると、storcli /cx[/ex]/sx insert dg=A array=B row=C のように指定してほちぃと言われているので、
下記のようにコマンドを投げます。
[root@nas GomenneGomenne-]# storcli /c0/e252/s7 insert dg=0 array=0 row=7 Controller = 0 Status = Success Description = Insert Drive Succeeded.

UGoodからOfflineにステータスが変わりましたが、RAIDアレイ自体はDgrdのままです。
まだ対象のDisk自体にデータの書き戻し（この1本だけ最新の状態に）更新されていない状態なので・・・
早速Rebuildを掛けます！
RAIDに参加させたHDDに対してReBuildを掛けたいので、下記のように指定します。

これで対象のHDDに対してデータの書き戻し処理が開始されました。
あとは終わるまで待つだけですね。
