This combination may result in data unavailability https://support.emc.com/kb/483810
KB里有详细的升级步骤，基本上照着Unisphere Service Manager的提示一路完成升级就行。升级过程是NDU的所以如果USM不报错的话可以在线完成升级。但一般都是建议在非高峰时段操作。
There is a common disk enclosure software (CDES 1.55 version) available to workaround this issue. This software is planned to be included in upcoming releases.
This is applicable on all arrays running 05.32.xxx.x.xxx and 05.31.xxx.x.xxx.
It performs a rebootless upgrade of the CDES by copying the CDES to the correct location on the array, then kicking off the upgrade process.
After NDU reports the operation is completed successfully, the user needs to wait for sometime to confirm that CDES has been updated. This is because, from NDU operation point of view, it is completed, but the CDES upgrade operation is a background task and will take a while to complete (the more enclosures, the longer it takes).
If an additional enclosure is added with an older version of CDES, then CDES 1.55 package should be installed again to upgrade the CDES.
For VNX1 arrays follow these steps:
Log in to the array using Unisphere Service Manager (USM).
Select Software > System Software > Prepare for Installation (Step 1) and follow the wizard. Browse and select the CDES 1.55 .ndu file you downloaded earlier and hit Next till you finish all the steps. Note: For Unified arrays kindly select the 3rd option: Verify storage environment for VNX OE for Block and/ or Enabler installation and follow the steps in the wizard.
Select Install Software (Step-2) in the USM and click Next and follow the steps in the wizard till the CDES 1.55 software is loaded on the array.
Note: For Unified arrays kindly select the 3rd option: Install VNX OE for Block and/ or Enabler and follow the steps in the wizard.
Once CDES 1.55 is loaded on the array, you can verify by clicking LCC and Power Supply Firmware Status in the bottom right Tools section of USM. Check show details in the LCC firmware tab and you can see the current LCC firmware version 1.55.
Note: You may need to wait for sometime to verify and confirm CDES 1.55 is loaded on the array (the more enclosures, the longer it takes).

hello,Roger
升级补丁前，需要注意什么，VNX有没有向网络交换机一样的配置文件，怎么备份？

最新的flare code已经包含了1.55，不过设备有报警的话是没办法升级的。

就像楼上说的，升级固件前尽量确保设备没有其他报警，不过通常USM的升级向导会在正式升级前向你确认的，跟着向导提示做就行。
备份VNX配置的问题以前有讨论过：EMC的配置数据文件是如何备份机制
Block部分，可以用USM (Unisphere Service Manager)工具来备份，登录VNX SP后，选择View System Configuration > Generate就可以生成存储SP配置的XML文件。也可以用Navisphere CLI命令行工具来完成这一操作：naviseccli -h arrayname arrayconfig -capture -output filename.xml。可以配合脚本定期执行这一命令。
File部分，Control Station会定期备份当前的系统配置，所以可以写一个脚本定期将/nas/var/backup下的nasdb_backup.xx.tar.gz文件复制到保存配置的地方。
