====== Solaris 10 設定 svm RAID 5編 ======
===== 準備 =====
VMにSCSI HDD 1.5G x 20 を追加する。
{{ :solaris:sun01_raid5_01.png?700 |}}
  * RAID 5のボリュームはディスク名d8で作成
  * 作成したボリュームはソフトパーティションで使用する

===== 手順 =====
追加したHDDの確認をformatにて行う。SCSI HDDの場合、devfsadm実行前に認識されていた。

領域の確保を行う。/var/tmp/04_fdisk.shを作成して実行する。
<code>
#!/bin/sh

04_fidisk.shによるfdiskの実行
<code>
# sh /var/tmp/04_fdisk.sh
#
</code>

RAID 5ボリュームを作成するために/var/tmp/05_raid5.shを作成する。
<code>
#!/bin/sh

metainit -f d8 -r c2t0d0s2 c2t1d0s2 c2t2d0s2 c2t3d0s2 c2t4d0s2 c2t5d0s2 c2t6d0s2 c2t8d0s2 c2t9d0s2 c2t10d0s2 c2t11d0s2 c2t12d0s2 c2t13d0s2 c2t14d0s2 c2t15d0s2 c3t0d0s2 c3t1d0s2 c3t2d0s2 c3t3d0s2 c3t4d0s2
</code>

05_raid5.shの実行
<code>
# sh /var/tmp/05_raid.sh
d8: RAID is setup
#
</code>

metainit実行後、状態の確認を行う。
