MegaRAIDで構成していたサーバから、エラーが上がり、デグレートしたので、取り外し調査をしてみた。

うーん。。。

やっぱり、死んだ。抜き差ししても認識しないので、マシンごと再起動。
認識したので、Smartをたたいてみた。

SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 12 occurred at disk power-on lifetime: 153 hours (6 days + 9 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
