修改MTU为9000

停crs
crsctl stop crs

aix:
chdev -Pl ent1 -a jumbo_frames=yes
chdev -Pl en1 -a mtu=9000

  linux:

查看mtu：ip l | grep bond_HB
及时生效：ifconfig bond_HB mtu 9000
永久生效：
cd /etc/sysconfig/network-scripts/
echo 'MTU=9000' >> ifcfg-bond_HB

测试命令：
traceroute -F node02-priv 9000
traceroute -F node02-priv 9001
ping -c 2 -M do -s 8972 node02-priv
ping -c 2 -M do -s 8973 node02-priv

  启动crs
  crsctl start crs

各平台ping测试

For Oracle Solaris, use: ping –D –s <IP> 8972

For Linux, use: ping –M do –s 8972 <IP>

For Microsoft Windows Server 2003 use: ping –f –l 8972 <IP>

In ESX shell, use: vmkping –s 8972 <IP>
