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 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843 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 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843 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 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 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843 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 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
AVAILABLE DISK SELECTIONS:
0. c0t0d0
/pci@0,0/pci8086,2829@d/disk@0,0
1. c0t2d0
/pci@0,0/pci8086,2829@d/disk@2,0
@硬盘被识别！
