A guide for troubleshooting CIFS issues on the Celerra

In my experience, every CIFS issue you may have will fall into 8 basic areas, the first five being the most common.   Check all of these things and I can almost guarantee you will resolve your problem. 🙂

1. CIFS Service.  Check and make sure the CIFS Service is running:  server_cifs server_2 -protocol CIFS -option start

2. DNS.  Check and make sure that your DNS server entries on the Celerra are correct, that you’re configured to point to at least two, and that they are up and running with the DNS Service running.

3. NTP.  Make sure your NTP server entry is correct on the Celerra, and that the IP is reachable on the network and is actively providing NTP services.

4. User Mapping.

5. Default Gateway.  Double check your default gateway in the Celerra’s routing table.  Get the network team involved if you’re not sure.

6. Interfaces.  Make sure the interfaces are physically connected and properly configured.

7. Speed/Duplex.  Make sure the speed and duplex settings on the Celerra match those of the switch port that the interfaces are plugged in to.

8. VLAN.  Double check your VLAN settings on the interfaces, make sure it matches what is configured on the connected switch.
