ORACLE EXADATA升級—從11.2.3.1.0到11.2.3.3.0–（8）升級交換機

	InfiniBand交換機的軟體安裝介質也是在cells裡面自帶的。使用和cells一樣的升級命令和方式。不過需要注意的一點是，交換機的網路卡資訊要和交換機主機下的/etc/hosts所配置的內容相同，如果不同，升級過程中會失敗。如下所示：


[FAIL     ] Mismatch between address in ifcfg-eth[0,1] and /etc/hosts in gxx2sw-ib3. ACTION: Correct entry in /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 or /etc/hosts



	此時需要我們登陸到InfiniBand交換機的主機上，透過ifconfig –a和more /etc/hosts兩個命令去查詢，修改好自己的/etc/hosts檔案後再次執行預檢測命令就能夠成功透過檢測了。
