Unix Study--Solaris 10添加新网卡
在Solaris 10上构建Oracle RAC ,在系统上添加了新的网卡，如何识别和配置相关的参数呢？本案例结合实际应用讲述如何配置第二块网卡
1、查看网卡名称
[root@node1:/]# ifconfig -a lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.8.11 netmask ffffff00 broadcast 192.168.8.255 ether 8:0:27:28:b1:8c
2、查看新网卡名称
[root@node1:/]# more /etc/path_to_inst
# # Caution! This file contains critical kernel state # "/iscsi" 0 "iscsi" "/pseudo" 0 "pseudo" "/options" 0 "options" "/xsvc" 0 "xsvc" "/objmgr" 0 "objmgr" "/scsi_vhci" 0 "scsi_vhci" "/isa" 0 "isa" "/isa/i8042@1,60" 0 "i8042" "/isa/i8042@1,60/keyboard@0" 0 "kb8042" "/isa/i8042@1,60/mouse@1" 0 "mouse8042" "/isa/lp@1,378" 0 "ecpp" "/ramdisk" 0 "ramdisk" "/cpus" 0 "cpunex" "/cpus/cpu@0" 0 "cpudrv" "/pci@0,0" 0 "pci" "/pci@0,0/display@2" 0 "vgatext" "/pci@0,0/pci106b,3f@6" 0 "ohci" "/pci@0,0/pci106b,3f@6/input@1" 0 "hid" "/pci@0,0/pci8086,1e@3" 0 "e1000g" "/pci@0,0/pci8086,2829@d" 0 "ahci" "/pci@0,0/pci8086,2829@d/disk@0,0" 0 "sd" "/pci@0,0/pci8086,2829@d/cdrom@1,0" 1 "sd" "/pci@0,0/pci8086,2829@d/disk@2,0" 2 "sd" "/pci@0,0/pci8086,1e@8" 1 "e1000g" "/agpgart" 0 "agpgart"
本机第一块网卡名称"e1000g0",则第二块网卡应为"e1000g1".
2、启用第二块网卡
[root@node1:/]# ifconfig e1000g1 plumb [root@node1:/]# ifconfig -a lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.8.11 netmask ffffff00 broadcast 192.168.8.255 ether 8:0:27:28:b1:8c e1000g1: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3 inet 0.0.0.0 netmask 0 ether 8:0:27:6e:16:1
3、添加网卡配置信息
[root@node1:/]# cat /etc/hosts # # Internet host table # ::1 localhost 127.0.0.1 localhost 192.168.8.11 node1 loghost 192.168.8.13 node1-vip 10.10.10.11 node1-priv ;;第二块网卡ip [root@node1:/]# cat /etc/hostname.e1000g1 node1-priv [root@node1:/]# cat /etc/netmasks # # The netmasks file associates Internet Protocol (IP) address # masks with IP network numbers. # # network-number netmask # # The term network-number refers to a number obtained from the Internet Network # Information Center. # # Both the network-number and the netmasks are specified in # "decimal dot" notation, e.g: # # 128.32.0.0 255.255.255.0 # 192.168.8.0 255.255.255.0 10.10.10.0 255.255.255.0 ;;第二块网卡子网掩码 [root@node1:/]# cat /etc/inet/ipnodes # # Internet host table # ::1 localhost 127.0.0.1 localhost 192.168.8.11 node1 loghost 192.168.8.13 node1-vip 10.10.10.11 node1-priv [root@node1:/]# sync;sync;reboot ;;重启系统 查看网卡信息，新网卡被启用： [root@node1:/]# ifconfig -a lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.8.11 netmask ffffff00 broadcast 192.168.8.255 ether 8:0:27:28:b1:8c e1000g1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3 inet 10.10.10.11 netmask ffffff00 broadcast 10.10.10.255 ether 8:0:27:6e:16:1
@至此，新网卡配置完成！
附注：
Solaris 10识别新硬盘：
添加新硬盘后，没有被识别，解决方法如下：
[root@node1:/]# touch /reconfigure
[root@node1:/]# sync;sync;reboot
[root@node1:/]# format
Searching for disks...done
