主題: [問題]請問Linux+Raid Card(已解決)

[andyj]

問個笨問題
我的系統是Redhat 7.3
安裝在SCSI上
我額外安裝一塊Promise的SX4000 Raid卡
上面一顆IDE
在/proc/module.conf自己有抓到那塊卡
請問那個IDE硬碟應該是/dev/hda1嗎?
直接Mount上去就可以了?
還是有其他作法??
不好意思沒做過這樣的事情....

[uck]

應該是/dev/hda .
您可以下 # fdisk /dev/hda  去看看.

除非您有分割 才有 /dev/hda1 .. /dev/hda2 等等的分割區.

[andyj]

#fdisk /dev/hda

Unable to Open dev/hda

這......
看了一下#vi /prco/pci
 Bus  0, device  17, function  0:
    RAID bus controller: PCI device 105a:6621 (Promise Technology, Inc.) (rev 1).
      IRQ 9.
      Master Capable.  Latency=96.  Min Gnt=6.Max Lat=18.
      I/O at 0xbc00 [0xbcff].
      I/O at 0xb800 [0xb8ff].
      I/O at 0xb400 [0xb4ff].
這應該代表有抓到卡....可是不曉得該怎麼看卡上的那個硬碟在哪邊怎麼mount與fdisk

[uck]

這樣說好了!!

例如:

您的Server上原本有 2顆 HD 分別是 hda 及 hdb .
       這一顆應該是 hdc .

1. 先將您的 Raid Card 卡設好. (不使用Raid 功能)
2. 將您要加上去的HD, Jump 調成 Master .
3. HD裝進您的Server. 排線,電源插好. 開機.
4. 其實在開機的過程中您就可以看到沒有沒抓到. 因為 Raid Card Bios 會秀出來它抓到的hd.
5. 開機後.看 dmesg 資訊. 看有沒有抓到.
6. fdisk /dev/hdc  ---> 不一定 hdc 哦..要看您的 hd 數量. 以此類推.
7. fdisk 做完後. 並 format hd
8. #mkdir /mnt/hdc
9. mount -t ext3 /dev/hdc /mnt/hdc
10.試試看.

為何不能使用raid 功能呢 ?
不啟動raid 卡如何 detect 那顆新增的 HD 呢 ?

我的Linux主系統在SCSI HD也就是sda
而上面再裝一塊ide raid卡(Promise SX4000/上有一顆250G的IDE HDD)
在開機有raid卡有抓到hd

The number of cylinders for this disk is set to 4462.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

剛剛致電給Promise這家公司的技術克服
答案因此出爐了...
因為使用yum去升級系統
導致Kernel跟著升級去了...
而她們的卡只有支援標準的7.3 Kernel
所以用這張卡以後就不能升級Kernel除非她們出新的Driver
原來的種種問題都在這上面
也謝謝各位的回應^_^
