查看服务器是否配置RAID以及HP RAID详情

有时候新接手维护服务器，或者在考虑当前服务器容灾备份机制时，首先得知道服务器到底是否存在RAID卡，是否已经配置RAID。最简单的方式就是重启服务器，然后根据提示查看相关信息。但很多情况下不能随便重启机器，那么我们可以通过特定的操作系统命令，或者查看相关日志得到该信息。注：此处讨论的是硬件RAID，不包括软件RAID

1、查看硬件是否支持RAID：

# lspci | grep RAID
02:00.0 RAID bus controller: Hewlett-Packard Company Smart Array Gen8 Controllers (rev 01)

该命令查看了当前服务器是否存在RAID控制器，如果输出类似上面的信息，则表示硬件支持RAID，但实际是否配置以及如何配置还得进一步确定。

2、查看系统是否配置RAID

# dmesg |grep -i raid
dracut: rd_NO_DM: removing DM RAID activation
dracut: rd_NO_MD: removing MD RAID activation
hpsa 0000:02:00.0: RAID              device c2b3t0l0 added.
scsi 2:3:0:0: RAID              HP       P420i            3.42 PQ: 0 ANSI: 5

如上所示，在系统日志中可以看到存在RAID设备，以及设备型号等信息。或者通过以下命令查看:

# cat /proc/scsi/scsi
Attached devices:
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: hp       Model: DVDRAM GT80N     Rev: EA02

Vendor: HP       Model: P420i            Rev: 3.42
Type:   RAID                             ANSI  SCSI revision: 05
Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: HP       Model: LOGICAL VOLUME   Rev: 3.42
Type:   Direct-Access                    ANSI  SCSI revision: 05
Host: scsi2 Channel: 00 Id: 00 Lun: 01
Vendor: HP       Model: LOGICAL VOLUME   Rev: 3.42
Type:   Direct-Access                    ANSI  SCSI revision: 05

该命令显示了当前系统做完RAID后的磁盘个数，其中第二项显示为RAID磁盘，但没有显示RAID级别。

3、查看服务器RAID磁盘详情

该部分内容通常无法通过系统自带命令或日志进行查询，需要使用RAID设备厂商提供的专用软件查看，此处以HP（惠普）服务器为例，进行演示。

上图所示，服务器做了两个RAID，分别是Array A 和 Array B，前者由两块硬盘组建了RAID 1，后者由四块硬盘组建了RAID 0。
