做HACMP切换实验的时候，如果进展不顺利，那就总要去机房插拔网线，太累，干脆用脚本模拟吧。现在只要把脚本粘到TELNET里就好了，方便多了。

1、模拟网络故障
cat <<'!' >/tmp/network-down
ifconfig en1 down
ifconfig en0 down
#notice: the seconds must > 360
sleep 600
ifconfig en1 up
ifconfig en0 up
rm -f /tmp/network-down
!
chmod +x /tmp/network-down
nohup /tmp/network-down
说明：ifconfig enX down和真正的拔网线还有点区别，也可以用ifconfig enX detach。

2、模拟单网卡故障
cat <<'!' >/tmp/1adapter-down
ifconfig en0 down
sleep 60
ifconfig en0 up
rm -f /tmp/1adapter-down
!
chmod +x /tmp/1adapter-down
nohup /tmp/1adapter-down

3、模拟节点故障
reboot -q

    另外，对上次的脚本做了一点修改，而且也是把下面的东东全粘到TELNET里，两个文件就自动生成了。
cat <<'EOF' >./ha1
#!/usr/bin/ksh
# Use this scrīpt before your adjusting HACMP
# Function: Clear these logs as follow.
cat <<'!' >/tmp/HAlogs
/tmp/hacmp.out
/tmp/clstrmgr.debug

/var/hacmp/clcomd/clcomddiag.log
/tmp/cspoc.log

for i in `cat /tmp/HAlogs`; do (cp $i $i.$suffix 2>/dev/null); done
for i in `cat /tmp/HAlogs`; do (> $i); done
EOF

cat <<'EOF' >./ha2
