hp Proliant ML110G5 続き

SATAケーブルを買ってきて HDD を追加。一応 diagnostics toolsでテストしたが、すごい時間かかるな。diagnostics toolsをいろいろみていたら BIOS characteristics の中に NEC PC-98 とかいう項目があることに気付いた。まだあるのかー。

cfdisk で Linux auto raid detect type な partition を作成。

serial consoleの設定はこうしておけばOKかな。 まず BIOS の Advanced Console Redirection で

• Console Redirection: Enabled
• EMS Console: Enabled
• Baud rate: 115.2K
• Console Type: VT100
• FLow Control: CTS/RTS
• Continue C.R After POST: Disabled

なんか「Continue C.R. After POST」をEnabledにしておくと grub の serial設定でささった。罠ぽい。 で GRUB の設定は次を追加

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=3 serial console

さらに/etc/inittabを

T0:23:respawn:/sbin/getty -L ttyS0 115200 vt102

こうしておくと Lights-Out 100 に telnet で login して、このserial経由でオペレーションできる。

% telnet aaa.bbb.ccc.ddd
Trying aaa.bbb.ccc.ddd...
Connected to aaa.bbb.ccc.ddd.
Escape character is '^]'.

ここで cd system1してresetで電源リセット、startで電源オン、stopで電源オフ など。 ESC-Q で serial consoleに attach。抜ける時は ESC-(。
