Windows CIFS share cannot be accessed on the Vnxe;
Unable to join the shared folder server to the domain;
Cannot create a shared folder on Vnxe;
Disk/Storage Pool failure-detected a time deviation;
The clock skew (clock skew) between the storage processor (SP) and the Windows domain controller is too large. To resolve time synchronization issues, you can set up a network Time Protocol (NTP) server or contact your Windows domain administrator.
Reason Analysis:
The clock (time) deviation between the storage processor (SP) and the Windows domain controller is too large (more than 5 minutes), causing the disk and storage pool to fail. When there is a communication failure, a time service failure, or the server is set to sync with a different time source, the server may lose synchronization. When this occurs, you may not be able to create a shared folder.
The shared folder server failed to join the domain because of the time bias between the Vnxe and the domain controller. Kerberos authentication is used for authentication between Vnxe and active Directory (AD), and Kerberos is a time-sensitive protocol.
Solution:
To resolve time synchronization issues, check the following:
· Whether the NTP server set up on the Vnxe has been started and is running.
· Whether to ping the NTP server from the storage processor.
· On a Network Time Protocol (NTP) server and a server with time synchronization issues, make sure that the Windows Time service is running and is set to run automatically. (This service is sometimes referred to as the W32Time service)
· The time zone and system time settings are correct. You can manually change the time on Windows Server to eliminate the clock skew between the two servers (changing the time) to ensure that there is no difference between the two servers for more than five minutes.
If the previous check does not resolve the issue, please contact EMC Technical Support for further investigation.
