Replication warnings in Celerra Manager after DR move
We had 2 NS20s on site. One was production, the other for DR/replication. When the replications were configured, both NS20s were on the same LAN and everyting was fine.
We eventually moved the DR NS20 offsite to a data center. The sites are connected with a 20mb fiber WAN connection.
After the move, we started receiving the following warnings in Celerra Manager. The replications are still working and marked OK, but 20-30 warnings pop up daily about drops in the connection.
Severity: Warning
Brief Description: Slot 2: Primary=fs31_T1_LUN0_APM00081800540_0000_fs27_T1_LUN0_APM00080701610_0000(alias=iSCSI_LUN0_Replication), transferring. Data connection down. Retry.
Full Description: communication between source and destination is down.
Recommended Action: Bring network communication between source and destination up for the data to be transferred from source to destination.
The warnings are either single entries or up to exactly one minute to the second. They happen with all of the replications that we have setup.
After running bandwidth montioring, we are only using 6-7mb of our 20mb pipe.
Although I do think this is a network connectivity issue, our provider of the fiber line says everything is fine. Other tests do not show any drops in the connection. The Celerra Manager is the only device reporting connection drops.
Has anyone seen these warnings after moving replications from a LAN to WAN connection? Is there settings in the Celerra to adjust because of the change in bandwidth?
