CIFS Operation
This section describes an operation in which the CIFS protocol is used.
In a Windows environment, domain-based operations are supported.
■
Switching between SMB1.0/2.0/3.0
For versions of the SMB protocol, SMB3.0 is enabled by default.
To change the version of the SMB protocol, execute the following procedure.
1
Specify the protocol version that is to be changed in the "-smb-version" parameter of the ETERNUS CLI "set
nas-server" command, and then execute the command.
2
Reestablish a session for the CIFS client that is to be connected.
Note
During the configuration phase
If the SMB protocol version was changed to SMB1.0 or SMB2.0 with the encryption function of SMB3.0
still enabled, disable the encryption function when accessing the shared folder.
■
Alternate Data Stream
The NAS file system in the ETERNUS DX supports the Alternate Data Streams (ADS). Multiple data streams can be
assigned to a file.
The ADS information cannot be preserved for the following cases.
•
If the file is moved or copied to a non-ETERNUS DX file system that does not support ADS.
If the file, regardless of whether it is in the ETERNUS DX, is moved or copied with protocols other than the CIFS
•
protocol.
Note that the access performance may be reduced if ADS information is added to a file. Also note that the total
capacity of ADS attributes that can be set is up to 96KB per file.
Caution
Older storage system models hold ADS information differently from the ETERNUS DX S5 series. Because of
this, the ADS information set in older storage system models cannot be migrated using REC.
