Workaround

When configuring the system to connect to an Active Directory domain:

 

1.

Ensure that you use FQDN and not the NETBIOS name of the domain or IP

 

 

address of the domain controller.

 

2.

Ensure that the user has permissions to add systems to the domain.

 

3.

Use the correct password.

 

4.

See DNS Configuration tab and enter the correct information.

 

5.

Configure the NTP information and ensure that the system time matches the

 

 

domain time.

 

6.

If multiple NAS systems are used, ensure that you set different NETBIOS names.

 

 

The system defaults to CIFS Storage as the name.

 

7.

Ensure that you select Authenticate users' identity via Active Directory and local

 

 

users database.

Troubleshooting Backup Issues

Troubleshooting Snapshots

Description Cause

Workaround

Taking and deleting snapshots fail.

Probable causes may be:

There are many client I/O requests waiting to be serviced, including a request to remove a large directory.

There are many snapshot creation/deletion requests being currently processed.

Another snapshot request for the volume is currently being executed.

The total number of snapshots reached the system limit.

Incorrect IP address was specified in the backup job.

For a manual request failure, retry taking or deleting the snapshot after a minute or two.

If the request originated from the snapshot scheduler, wait another cycle or two. If the failure persists, try taking or deleting the snapshot manually on the same volume.

Check the dashboard if the system is under heavy workload. If the system is under a heavy workload, wait until the workload decreases and reissue the snapshot request.

Check the snapshot schedule. A very dense snapshot schedule has a negative impact on the overall performance of the system. The accumulated snapshot rate must not exceed 20 snapshots per hour per system.

Check the total number of snapshots in the system. If the number is in thousands, delete a few snapshots and retry.

Ensure the Client virtual IP address is specified in the backup job.

Troubleshooting An NDMP Internal Error

Description

Backup or restore fails with an internal error.

Cause

NDMP internal errors are indicators of a file system not being accessible or a NAS

 

volume not being available.

Workaround

If the backup application cannot connect to a NAS appliance:

 

1. Log in to the NAS Manager or open a remote terminal to the appliance.
