___ VNX5300存储NAS日常操作手册和故障处理

如果需要创建一个超大的NAS文件系统（nas01）15T，给多台服务器共享使用，且每个服务器只能识别到自己专有的子NFS文件系统，彼此之间日常操作不会受影响，即隔离了敏感数据的涉密，也避免了操作上的风险，需要进行以下操作：进入“Storage”菜单下的“Storage n”页面，进入“File System”界面的“Tree Quotas”页面，点击“Create”按钮。

To create a sub-file system, select the parent file system, input

the sub-file system path, add a note, and specify the size and file

limit. After confirming the details, click OK to complete the n of

the sub-file system.

To create an NFS, go to Storage > Storage Folders > NFS and

click the "create" button. Select the correct parent file system for

FileSystem, manually enter the sub-file system created earlier in

Path, and click OK after verifying all other details. The sub-file

system and NFS are now created and can be mounted on the host

machine.

To expand the NAS file system shared storage pool, we need

to avoid the storage pool from getting full and affecting the normal

n of the business system. Therefore, we need to expand the storage

pool. As shown in the figure below, the usage of the shared file

system storage pool has reached 97%.

On the following page, we can see that there are only six TB

left in RAID GOUP 7. Click the create button to create a LUN that

meets the ___ size, LUN ID, quantity, and LUNNAME in the sub-interface ADVANCED, and then click APPLY to create the LUN

successfully.

Select the newly added LUN and click the "ADD TO

STORAGE GROUP" button to add it to the file system storage

pool that needs to be expanded.

On the next page, click "Rescan Storage Systems" to

manually refresh the page. After a short wait, the total storage

space will increase and the ___ decrease.

To access the NAS NFS shared storage directly on Windows

Server 2008, open the DOS window (not PowerShell) and type the

command " -install FS-NFS-Services" to

install NFS services. After n, run the command "net use /" to make

the disk mapping permanent after system restart. To avoid the

read-write error message when mounting NFS, create a new

notepad file and enter the following text: "Windows Registry

Editor n 5.00."

6. In the LongXX data center NAS storage system's "Settings

for File" interface, change the original IP address to the newly

assigned one. Note that once the n nship is established, the IP

address cannot be ___, only added.

重新配置存储两端的IP地址互信，以进行数据复制。

n for file界面，点击Create按钮，定义源端和目标端的IP地址（长XX存储为源端，湘XX存储为目标端），然后点击OK。接着，n for file界面，同样进行IP地址的定义（湘XX存储为源端，长XX存储为目标端），然后点击OK。

建立文件系统的复制关系。

n for file界面，点击Create按钮，选择replicate a file

system，并确保以下信息无误后点击OK：n Name（自定义名称）、Soure File system（选择需要复制的NAS文件系统）、n System（选择目标端）、Source Data Mover Interconnect（选择源数据内部移动者）、Source Interface（输入源端用于复制的IP地址）、n Interface（输入目标端用于复制的IP地址）、Create n（目标端创建路径的方式）、n Pool（选择目标端存储池）、n Checkpoint Storage（目标端存储检查点）、Update

Policy（同步策略）、Time Out of Sync（异步同步时间间隔）、___（是否用磁带传输）。

故障处理。

在NAS的web管理界面中，无法看到已分配的file

system。通过SSH登陆控制台后运行nas_pool -list和nas_fs

nas_name，发现CS发生过切换，主控制台应该在CS0上，而现在CS1为主控制台，CS0为备控制台，说明发生过一次控制台切换。
