ESXi 5 启用ISCSI后启动缓慢

       在ESXi 5.0 启用了软ISCSI后，并且挂载了大的目标卷，如果这个LUN不能到达就会导致启动缓慢，等其启动后在sysboot.log 中看到以下内容：

[01:57:50.925338] sysboot: software-iscsi
[02:28:22.330320] sysboot: restore-paths
iscsid: cannot make a connection to 192.168.1.20:3260 (101,Network is unreachable)

解决办法：需要安装ESXi500-201111001补丁程序
