一个Sun Blade X6270 M2服务器模块有四个146GB磁盘 ，但正在运行的RHEL5-x64操作系统只能find一个146GB的磁盘。 我猜想四个磁盘中有两个是RAID 1卷 – 一个是操作系统发现的。 剩下的两个磁盘未使用。
我需要一个工具来（至less） 显示当前的RAIDconfiguration，并configuration另外两个磁盘来创build一个新的RAIDfunction，并将其提供给操作系统 。
你知道有什么工具可以实现吗？
我尝试使用ILOM-CMM，但没有find磁盘驱动器信息。
提前感谢
sas2ircu是获取该信息的Avago技术工具。 不需要安装 – 该工具是一个单一的二进制文件（ 点击此处浏览下载页面 ）。

# ./sas2ircu list LSI Corporation SAS2 IR Configuration Utility. Version 11.00.00.03 (2011.10.14) Copyright (c) 2009-2011 LSI Corporation. All rights reserved.

您知道控制器ID，您可以使用status命令获取有关RAID卷的信息：
# ./sas2ircu 0 status LSI Corporation SAS2 IR Configuration Utility. Version 11.00.00.03 (2011.10.14) Copyright (c) 2009-2011 LSI Corporation. All rights reserved.

SAS2IRCU: Utility Completed Successfully.
或者使用display命令获取所有的细节：

在这里您可以看到内部SAS磁盘的RAIDconfiguration：2个磁盘用于RAID-1卷和2个热备用磁盘。
