[[ SATA box の設定 (公開)]]

2008.10 現在 flex に接続している SATA HDD Box の設定方法を記録。

2008.10.25 by R. Saito

SATA box でハードディスクを認識するには、 sata_sil24 というドライバーを除き si3132r5.ko というドライバーをインストールする必要がある。 以下はその手順と、その後のフォーマットの方法を示したもの。

機種名

PCIe interface カードに対する driver の作製。

Linux Kernel に driver module の組み込み

cd /lib/modules/2.6.9-67.0.7.ELsmp/kernel/drivers/scsi
lsmod
rmmod sata_sil24
insmod si3132r5.ko
alias scsi_hostadapter1 sata_sil24 <- あったら削除
alias scsi_hostadapter1 si3132r5 <- 追加

電源を入れ、device の認識の確認。

flex48:scsi% cat /proc/scsi/scsi

 Partition の作製

[root@flex scsi]# tcsh
[rsaito@flex scsi]$ setenv LANG C
[rsaito@flex scsi]$ fdisk /dev/sdf
Device contains neither a valid DOS partition table, nor Sun, 
SGI or OSF  disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 121601.
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)

 今後の方針

/dev/sde -> /misc/sata1

 tube の /home1 など、ファイルサーバーをこの SATA BOX にまとめる。

FLEXからmountで見ると
172.17.4.129:/pmphdd1 on /pmphdd type nfs (rw,addr=172.17.4.129) 
となっているHDDです。

 RAID の設定を考える。RAIDの勉強が必要。安全性を重視。
