Hello everybody,
I've a Network Attached Storage HP X5520 G2 with Windows Storage 2008 R2 and five clustered file servers with several issues; everydays, at 6.00 AM and 12.00 PM, there're many Network Manager errors like this:
Event 1129:
Cluster network 'Public' is partitioned. Some attached failover cluster nodes cannot communicate with each other over the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
Or Event 1126
Cluster network interface 'ClusterNode2 - 10 GbE Public 1' for cluster node 'ClusterNode2' on network 'Public' is unreachable by at least one other cluster node attached to the network. The failover cluster was not able to determine the location of the failure. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
These errors cause cluster network downtime on both cluster nodes;
After a first analysis, I've found that at 6.00 AM and 12.00 PM a VSS of a very large file server (with a 40 TB LUN) occurs; It may be due to this fact? How can I solve this issue?
Thank you very much
Daniele
