# 磁碟管理-StorCLI

這款機器的 Local Disks 都連結在內建的 MegaRAID (MegaRAID SAS-3 3108) 介面上，如果系統已經安裝好 Linux，可以透過指令 lshw 確認這個裝置存在。

> 雖然有 Raid 卡，卻無法建立 Raid，從 Petitboot 指令模式下，使用 storcli 指令新增 Raid 失敗。  
> 錯誤訊息: Resources already in use

##### 下載安裝 StorCLI

下載網址：https://www.broadcom.com/support/download-search/?pg=&pf=&pn=&po=&pa=&dk=storcli

StorCLI for Linux 其實只是一個編譯過的指令 storcli (storcli64 for 64-bit)，官方只是將這指令包裝成 RPM 或 DEB 方便用戶在可以在不同的作業系統版本做安裝；只是筆者從連結下載的壓縮包，解開後找不到 PPC64LE for RedHat，但有看到 PPC64LE for Ubuntu (\*.deb)，所以只要用另一部 Windows 或 Linux 電腦將 \*.deb 解開就會看到一個檔案 `storcli64` 。

將這個檔案複製到已經安裝好的 RedHat Linux 即可使用。

> storcli64 也能用在 Petitboot，直接用 scp 或 wget 從外部電腦複製。
