Troubleshooting RX And TX Pause Warning Messages

Description

The following warning messages may be displayed when the NAS Manager reports

 

connectivity in a Not Optimal state:

 

Rx_pause for eth(x) on node

 

1 is off.

 

Tx_pause for eth(x) on node 1 is off.

Cause

Flow control is not enabled on the switch(es) connected to a NAS cluster solution

 

controller.

Workaround

See the switch vendor's documentation to enable flow control on the switch(es).

Troubleshooting Replication Issues

Replication Configuration Error

Description

Replication between the source and destination NAS volumes fails because the source

 

and destination systems’ topologies are incompatible.

Cause

The source and destination systems are incompatible for replication purposes.

Workaround

Upgrade the NAS cluster solution which is down. Verify that both the source and

 

destination have the same number of NAS controllers.

 

NOTE: You cannot replicate between a four-node NAS cluster and two-node

 

NAS cluster.

Replication Destination Cluster Is Busy

Description

Replication between the source NAS volume and the destination NAS volume fails

 

because the destination cluster is not available to serve the required replication.

Cause

Replication task fails because the destination cluster is not available to serve the

 

required replication.

Workaround

Administrators must verify the replication status on destination system.

Replication Destination FS Is Busy

Description

Replication between the source NAS volume and the destination NAS volume fails.

Cause

Replication task fails because the destination cluster is temporarily unavailable to

 

serve the required replication.

Workaround

The replication continues automatically when the file system releases part of the

 

resources. Administrators must verify that the replication continues automatically after

 

a period of time (an hour).

Replication Destination Is Down

Description

Replication between the NAS source volume and the NAS destination volume fails.

Cause

Replication task fails since the file system of the destination NAS volume is down.

Workaround

Administrators must check if the file system is down in the destination system using

 

the monitoring section of the NAS Manager. If the NAS cluster solution file system is

 

not responding, administrators must start the system on the destination cluster. The

 

replication continues automatically after the file system starts.
