vSphere Distributed Switch MTU mismatch

Based on event

Error

Manual

A larger MTU (maximum transmission unit) bring greater efficiency because each packet carries more user data while protocol overheads; the resulting higher efficiency means a slight improvement in bulk protocol throughput. A larger MTU also means processing of fewer packets for the same amount of data. However, this gain is not without some downside. Large packets can occupy a slow link for some time, causing greater delays to following packets and increasing lag and minimum latency.

Description

Duplicate IP address detected

Based on event
DuplicateIpDetectedEvent.

Warning

Manual

This event records that a duplicate IP address has been observed, with conflict between VM, and the vMotion or IP storage interface configured on the host.

Host cluster destroyed

Based on event
ClusterDestroyedEvent.

Information

Automatic

This event records when a cluster is destroyed.

Host failure detected

Based on event
DasHostFailedEvent.

Error

Manual

This event records when a host failure has been detected by HA.

Host isolation in HA cluster

Based on event
DasHostIsolatedEvent.

Warning

Manual

This event records that a host has been isolated from the network in a HA cluster. Since an isolated host cannot be distinguished from a failed host except by the isolated host itself, this event is logged when the isolated host regains network connectivity.

No host redundant management network available

Based on event
HostNoRedundantManagementNetworkEvent.

Warning

Manual

This event records the fact that a host does not have a redundant management network. It is recommended that host management networks be configured with redundancy.

Primary host connection re-established

Based on event
DasAgentFoundEvent.

Information

Automatic

This event records that vCenter Server has re-established contact with a primary host in this HA cluster.

Primary host unavailable

Based on event
DasAgentUnavailableEvent.

Error

Automatic

This event records that vCenter Server cannot contact to any primary host in this HA cluster. vCenter Server has lost contact with all primary nodes with a connected state. Attempts to configure HA on a host in this cluster will fail until a DasAgentFoundEvent is logged or unless this is the first node to be configured. For example, if all the other hosts are disconnected first.

Based on event
DasAgentFoundEvent.

Resource pool configuration conflict

Based on event
ResourceViolatedEvent.

Error

Manual

This event records when a conflict with a resource pool's resource configuration is detected.

Storage ATS support failure

Based on event
esx.problem.vmfs.ats.support.lost.

Error

Manual

In a shared storage environment, when multiple hosts access the same VMFS datastore, specific locking mechanisms are used. These locking mechanism prevent multiple hosts from concurrently writing to the metadata and ensure that no data corruption occurs. VMFS supports SCSI reservations and atomic test and set (ATS) locking. For storage devices that support hardware acceleration, VMFS uses the ATS algorithm, also called hardware assisted locking. In contrast with SCSI reservations, ATS supports discrete locking per disk sector.

Task timeout reached

Based on event
TaskTimeoutEvent.

Warning

Manual

This event records when a task exceeds defined timeout in vCenter Server.

Template deployment failure

Based on event
VmDeployFailedEvent.

Error
