Create Shared Folder
Overview
This function creates shared folders.
Specify the access protocols, hosts which are allowed or denied access, and CIFS access permissions to each shared folder.
This function also creates home directories. The home directory is a type of shared folder.
This function is used in a Unified Storage environment.
Number of Shared Folders That Can Be Registered
Protocol | Number of shared folders (*1) |
---|---|
Windows CIFS | 256 |
UNIX NFS | 256 |
Total number of Windows CIFS and UNIX NFS | 256 |
*1 | : | The maximum number of shared folders may be less in some operating environments. |
- The following settings must be performed before creating shared folders.
Create the TPPs that are to be used in the Unified Storage environment. Refer to the [Create Thin Provisioning Pool] function for details.
This function creates NAS user volumes. Refer to the [Create Volume] function for details.
Confirm that the authentication server setup is complete in advance. To set the authentication server, use the [Set Authentication Server] function.
An error occurs when the total number of input characters exceeds the maximum (5120 characters). Confirm the used characters when this error occurs even if the total of input characters does not exceed the maximum. Note that a double quotation (0x22) and a single quotation (0x27) are regarded as being two characters.
If the shared folder creation has not been completed successfully, wait for the storage system status to return to normal and then try again.
If shared folders are created in the NAS user volume where a meta cache redistribution is being performed, the process may be delayed for a maximum of two minutes.
The CIFS access permission is enabled from the next CIFS access session that is established after the permission is set.
- When a new shared folder is created, the following setup items are automatically specified for the created shared folder.
"Yes (Writable)" is specified for "Writable"
"Disable (Not use)" is specified for "Oplocks"
"Home directory" is created for each user and is used as a dedicated shared folder that can be used freely by the user. Users use the home directory with a CIFS connection. Home directories can be used by users that are authenticated by the Active Directory authentication server or the local user authentication.
