本次由于需要搭建一套环境，但是所需硬件配置不足，需要进行统计采购。那么就需要得知服务器现有配置，所以这次会介绍些常用的命令和工具来查询硬件信息。其实也可以通过像DELL厂商的IDRAC控制台来获取这些信息，但是比较尴尬的是IBM在获取硬盘信息方面支持比较差，仅显示物理磁盘数量，能够获取的信息很少，这时就需要像storcli这种专业工具来收集。本章使用的命令查询需求比较单一，后续会在实际使用中慢慢补充上来。
一、查看服务器对应 IPMI 地址
[root@node-1 ~]# ipmitool lan print

[root@node-1 ~]# lspci | grep Ethernet #列出每个pci总线上的设备，通过grep过滤可得到网卡设备列表，这里看到总计8个网卡
06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

[root@node-1 ~]# cat /proc/meminfo
[root@node-1 ~]# dmidecode -t memory #此命令会列出每条内存的型号、频率等详细信息
Handle 0x000A, DMI type 17, 34 bytes

[root@node-1 ~]# rpm -ivh storcli-1.18.05-1.noarch.rpm #安装包请见文章末尾
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 show all #查询所有信息并show，在system overview下看到controller（缩写ctl）列数字就是controller号，得知node-1这台机器的controller号是0
System Overview :

如果不需要其他信息，和我一样只需要知道物理磁盘信息的话可以使用如下命令
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 /c0/eall/sall show
Controller = 0

-------------------------------------------------------------------------五、不想安装 storcli 的情况下查看硬盘型号信息
[root@node-1 ~]# cat /proc/scsi/scsi|grep 'Model:' #node-1 是 IBM X3650 M4
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM SATA Model: DEVICE 81Y3682 Rev: D001[root@node-5 ~]# cat /proc/scsi/scsi|grep 'Model:' #node-5 是 DELL R720，ST1000NM0023就是硬盘的型号
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0F
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D这种方式在硬盘做 raid 后不便于查看，例如下面查看我另一台服务器所看到到的，显示只有一块磁盘设备
[root@node-1 ~]# cat /proc/scsi/scsi|grep 'Model:'
Vendor: DELL Model: PERC H710 Rev: 3.13
Vendor: TSSTcorp Model: DVD-ROM SN-108FB Rev: D150接下来通过 lsblk 查看设备情况，发现这块盘总容量2.7T（我这里使用的盘是1T的SAS盘，可以倒推出是4块1T盘组成的raid5）正好对应上我在IDRAC界面中看到的四块物理磁盘
[root@node-1 ~]# lsblk
