檢視伺服器硬體配置資訊
本次由於需要搭建一套環境，但是所需硬體配置不足，需要進行統計採購。那麼就需要得知伺服器現有配置，所以這次會介紹些常用的命令和工具來查詢硬體資訊。其實也可以通過像DELL廠商的IDRAC控制檯來獲取這些資訊，但是比較尷尬的是IBM在獲取硬碟資訊方面支援比較差，僅顯示物理磁碟數量，能夠獲取的資訊很少，這時就需要像storcli這種專業工具來收集。本章使用的命令查詢需求比較單一，後續會在實際使用中慢慢補充上來。
一、檢視伺服器對應 IPMI 地址
[[email protected] ~]# ipmitool lan print
Set in Progress : Set Complete Auth Type Support : NONE MD2 MD5 PASSWORD Auth Type Enable : Callback : : User : MD2 MD5 PASSWORD : Operator : MD2 MD5 PASSWORD : Admin : MD2 MD5 PASSWORD : OEM : IP Address Source : Static Address IP Address : 10.100.0.40 Subnet Mask : 255.255.255.0 MAC Address : 40:f2:e9:da:53:fe SNMP Community String : public IP Header : TTL=0x40 Flags=0x40 Precedence=0x00 TOS=0x10 BMC ARP Control : ARP Responses Enabled, Gratuitous ARP Disabled Gratituous ARP Intrvl : 2.0 seconds Default Gateway IP : 10.100.0.1 Default Gateway MAC : 00:00:00:00:00:00 Backup Gateway IP : 0.0.0.0 Backup Gateway MAC : 00:00:00:00:00:00 802.1q VLAN ID : Disabled 802.1q VLAN Priority : 0 RMCP+ Cipher Suites : 1,2,3,4,5,6,7,8,9,10,11,12,13,14 Cipher Suite Priv Max : aaaaaaaaaaaaaaX : X=Cipher Suite Unused : c=CALLBACK : u=USER : o=OPERATOR : a=ADMIN : O=OEM
二、檢視網絡卡速率
[[email protected] ~]# lspci | grep Ethernet #列出每個pci總線上的裝置，通過grep過濾可得到網絡卡裝置列表，這裡看到總計8個網絡卡
06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 11:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10) 11:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10) 20:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10) 20:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
[[email protected] ~]# ethtool eth0 #檢視單塊網絡卡的詳細資訊

[[email protected] ~]# cat /proc/meminfo
[[email protected] ~]# dmidecode -t memory #此命令會列出每條記憶體的型號、頻率等詳細資訊

[[email protected] ~]# rpm -ivh storcli-1.18.05-1.noarch.rpm #安裝包請見文章末尾
[[email protected] ~]# /opt/MegaRAID/storcli/storcli64 show all #查詢所有資訊並show，在system overview下看到controller（縮寫ctl）列數字就是controller號，得知node-1這臺機器的controller號是0
System Overview :

如果不需要其他資訊，和我一樣只需要知道物理磁碟資訊的話可以使用如下命令
[[email protected] ~]# /opt/MegaRAID/storcli/storcli64 /c0/eall/sall show

-------------------------------------------------------------------------五、不想安裝 storcli 的情況下檢視硬碟型號資訊
[[email protected] ~]# 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[[email protected] ~]# cat /proc/scsi/scsi|grep 'Model:' #node-5 是 DELL R720，ST1000NM0023就是硬碟的型號
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0F
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D這種方式在硬碟做 raid 後不便於檢視，例如下面檢視我另一臺伺服器所看到到的，顯示只有一塊磁碟裝置
[[email protected] ~]# cat /proc/scsi/scsi|grep 'Model:'
Vendor: DELL Model: PERC H710 Rev: 3.13
Vendor: TSSTcorp Model: DVD-ROM SN-108FB Rev: D150接下來通過 lsblk 檢視裝置情況，發現這塊盤總容量2.7T（我這裡使用的盤是1T的SAS盤，可以倒推出是4塊1T盤組成的raid5）正好對應上我在IDRAC介面中看到的四塊物理磁碟
[[email protected] ~]# lsblk
