This document will list some of the more common causes of loss of general network connectivity.  Where the problem is not specific to one particular data service protocol or clients of a particular directory service, and affects both the Management Interface and client data share access equally.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance Community

Troubleshooting Steps
 1. General Checks for Network Outages
 2. Loss of network following configuration change
 3. One or more interfaces in an IPMP group are marked as failed
 4. Other causes of network problems
 Packet loss when using Link Aggregation with devices connected to separate network switches:
 Loss of network connectivity to either or both Management Interface and Client Access to shares when using SNMP to monitor many interfaces:
 nge interfaces may disappear:
 Network Devices only connect at half-duplex:
 On a cluster setting "allow admin" may cause loss of default route on the peer head:
 Loss of network configuration ability in a 7410 cluster:
 Maximum speed of interface is limited at 100 Mb/s when directly connected with a 'cross cable'
