一Sun Blade X6270 M2 服务器模块有四个146GB 磁盘，但正在运行的 RHEL5-x64 OS 只找到一个 146GB 的磁盘。我猜这四个磁盘中有两个是 RAID 1 卷（即 OS 找到的那个）；其余两个磁盘未使用。
我需要一个工具（至少）显示当前 RAID 配置并配置其他两个磁盘以创建新的 RAID 卷并使其可供操作系统使用。
您知道有什么工具可以实现这一目标吗？
我尝试使用 ILOM-CMM，但找不到磁盘驱动器信息。
提前感谢

sas2ircu是一个安华高科技工具来获取该信息。无需安装 - 该工具是一个二进制文件（点击此处浏览其下载页面）。
# ./sas2ircu

SAS2IRCU: No command specified.
sas2ircu <controller #> <command> <parameters> ...
where <controller #> is:
Number between 0 and 255
where <command> is:
DISPLAY - display controller, volume and physical device info
LIST - Lists all available LSI adapters (does not need ctlr #>
CREATE - create an IR volume
DELETE - Delete entire RAID configuration on the selected controller
DELETEVOLUME - Delete a specific RAID Volume on the selected controller
HOTSPARE - make drive a hot spare
STATUS - display current volume status info
CONSTCHK - Start Consistency Check operation on the specified IR Volume
ACTIVATE - Activate an Inactive IR volume
LOCATE - Locate a disk drive on an enclosure
LOGIR - Upload or Clear IR Log data
BOOTIR - Select an IR Boot Volume as primary boot device
BOOTENCL - Select an Enclosure/Bay as primary boot device
HELP - Display help information
where <parameters> are:
Command specific values; enter "sas2ircu <controller #> <command>"
to get command specific help
sas2ircu命令需要控制器编号（或索引）。该控制器编号由列表命令：
# ./sas2ircu list

一旦您知道控制器 ID，就可以使用地位命令获取有关 RAID 卷的信息：
# ./sas2ircu 0 status
