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.
