This document contains the list of Top Services Topics for VxRail Appliance, identified by EMC Support as the most trending topics for the month of May 2019:
It is recommended that you also check for important information such as advisories (ETAs, ESAs), and other key resources on the “Support by Product” pages on the EMC Online Support portal.
In a cluster where one power supply receives high line voltage (200-240V) and the other receives low line (100-120V), the low line power supply shows as "incorrectly configured" and power redundancy is unavailable.
This article describes how to fix inability to create VSAN disk groups or add disks to existing ones when there are abnormal conditions showing on the host.
Multibit errors across multiple DIMMs may be reported on a VxRail Gen 5 nodes within a few seconds after a reboot due to CPU IERR or Machine Check.
After upgrading to VxRail Code 4.7.x, ESXi hosts in the cluster have an alert which states: TPM 2.0 device detected but a connection cannot be established.
When ESXi is updated through VMware Update Manager (VUM) it causes the custom VxRail vSphere Installation Bundle (VIB) to malfunction which leads to services that start and stop in vCenter, hosts missing on the VxRail physical page, and upgrade failures.
VxRail is an engineered appliance, not an off-the-shelf VMware product, so upgrades have to be done through VxRail Manager and the approved VxRail Code upgrade packages.
Thick-provisioned VMs on vSAN detected on vSAN-health check
Dell EMC VxRail: After upgrade to 4.5.300/4.7.100, the VxRail cluster running on Dell PowerEdge servers may encounter high IO latency and poor VM performance resulting in application failure due to the HBA 330 fw/driver issue.
After upgrade to 4.5.300/4.7.100, the VxRail cluster running on Dell PowerEdge server may encounter high IO latency and bad VM performance resulting in application failure due to the HBA 330 fw/driver issue.
A host shows 'disconnected' or 'not-responding' in the vCenter web client. The host can still be shown to be running, and Virtual Machines (VMs) may still be running fine on it. However, the host is not manageable from vCenter and may not respond well in other ways, and the VMs running on the host cannot be migrated to other hosts in the cluster using vmotion.
