Hello, everyone!
After a CIFS share is created on OceanStor 5500 V5, the shared directory cannot be mounted to the SUSE11 operating system.
Symptoms
On OceanStor 5500 V5, the NAS function is enabled, a CIFS share is created, and the shared directory cannot be mounted to a server. For example, the shared directory cannot be mounted to SUSE 11. CentOS and Windows 2008 can be mounted properly.

Cause
SMB 1.0 is used to access the CIFS share on the SUSE 11 client, and SMB 2.0 is used to access the Windows 2008/Center OS. SMB 1 is disabled on the storage end by default.
Analysis
1.Log in to the CLI and run the show service cifs command as the admin user.

2. If SMB1 ENABLED is NO, enable SMB1.
The command is as follows:
admin:/>change service cifs smb1_enable=yes

3. Run show service cifs command again

Solution
Run the following command to enable SMB1 on the storage device:
admin:/>change service cifs smb1_enable=yes
That's all, thanks!
