This module demonstrates how to provide CIFS storage access to a VNX system.
This lesson demonstrates how to create and join a CIFS server into the domain.
The Create CIFS Server configuration window has several sections for creating and configuring a CIFS server. The first section has a drop-down to select the Data Mover that will hold the CIFS server. The Data Movers can be physical or Virtual Data Movers. The Server Type section defines the behavior of the CIFS server. There are three options of CIFS servers: Windows NT4 (Windows NT domain member), Windows 2000/2003/2008 (AD membership) and standalone (local login) servers. The section will have different fields corresponding to the type of server selected. The screen show has fields for the Windows 2000 Computer Name, Aliases and NetBIOS Name. The slide illustrates creating a Windows 2000/2003/2008 server named cifs01. Next is the Domain section which has fields for the Windows Domain, a checkbox option for joining the domain, credential fields for a Domain user with the rights to add computers into the domain and the Organizational Unit that the CIFS server will be added into. The default organizational unit (OU) for a Data Mover’s CIFS server is Computers:EMC Celerra.The next section is for enabling local users on the CIFS server and setting a local Admin password.The final step is to select an interface. If no interface is specified, the associated CIFS server uses all unassigned interfaces on that Data Mover. This configuration is known as the default CIFS server.To verify if server was configured properly use the CLI command: server_cifs <movername>
This lesson focuses on making a file system available to a CIFS client.
To export a file system for CIFS, in Unisphere click Storage > Shared Folders > CIFS > Create. The first step for creating a CIFS share is to select a Data Mover for the share, it is selected from a drop-down menu. Only Primary Data Movers will be displayed – either physical or Virtual Data Movers. In the CIFS Share Name field, a share name must be input. The share name will be the name of the share that the CIFS server presents to the network. It does not have to be the same name as the file system pathname that is exported. Next, select the desired File System from the drop-down menu. Only file systems that are mounted to the selected Data Mover will be displayed. Next select the file system Path name to export. When creating an initial share on a file system, the only pathname available will be to the top-level of the file system. The field only accepts pathnames that exist and it will not create any structure that does not already exist. Make sure you check the corresponding CIFS Server. Click OK when done.
The CIFS service must be stopped and restarted for any changes in the configuration to take effect. Such change could include but not be limited to: Adding/changing the External Usermapper address Adding/changing the address of the WINS server Changing the security modeTo start or stop CIFS, access the main CIFS page, then from the Tasks pane File Storage section, select Configure CIFS.
Deleting a CIFS server is a multi-step process. Please note that a CIFS server can be removed directly in Unisphere without performing all these steps. These steps represent a best practice for removing a CIFS server to prevent any data loss from in-process write operations or incomplete removal.The first step is to ensure that there are no users actively accessing the CIFS server. This can be done using Computer Management and connecting to the CIFS server and checking for any open sessions to users.The next step is to remove the CIFS server from the domain. This is done in the Unisphere GUI on the main CIFS page. Select the specific CIFS Server’s properties and perform the unjoin operation.Next is to delete any CIFS shares that are specifically associated with the CIFS Server. This is done in the Unisphere GUI on the main CIFS page. From the CIFS Shares tab, select Shares related to the CIFS server and delete them. The delete shares operation does not delete data from the file system, it simply removes the sharing of the data.Finally the CIFS server can be deleted. From the main CIFS page in Unisphere, select the specific CIFS server from the CIFS Servers tab and delete it.Using this multistep process prevents removal of a CIFS Server when write operations are in process and clears the CIFS configuration of the CIFS Server completely.
