Release Notes

Operating system takes more time to complete boot
when Intel DCPMM is configured in the interleaved
app-direct mode
Description: Dell EMC PowerEdge servers with the VMware ESXi operating system installed take more time to
complete boot when Intel® Optane DC Persistent Memory (DCPMM) is configured in the interleaved
app-direct mode. The time taken to complete the boot depends on the capacity, configuration, and the
number of sockets on the server. Messages such as: Attempt to allocate zero bytes,
allocating 1 byte from the VMkernel log can be ignored. A similar issue is documented when the
VMware ESXi operating system takes a longer time to complete boot when DIMMs are configured in non-
interleaved sets. For more information, see Dell EMC DCPMM User's Guide.
Applies to: ESXi 6.7.x, 7.0.x
Systems
affected:
Dell EMC PowerEdge servers that support Persistent Memory (PMEM)
Tracking number: 174273
The health status of the SD cards are not updated
under the Hardware Health tab
Description:
The health status of the SD card from the Dell Internal Dual SD Module (IDSDM) is displayed as
Unknown on the respective Hardware Health tabs of the VMware ESXi web client and the vCenter web
client.
Applies to: ESXi 6.7.x
Workaround: The iDRAC page displays the status of the IDSDM SD cards correctly.
Systems
affected:
All Dell EMC PowerEdge servers.
Tracking number: 101450
Network connectivity is lost when virtual machines
configured with Virtual Guest Tagging (VGT) are
migrated to another ESXi host
Description:
When virtual machines that are configured with 802.1q VLAN tagging are migrated to another ESXi host,
the network connectivity is lost. The network connectivity is reestablished within a few minutes without
any user intervention.
Applies to: ESXi 6.7.x
Cause: VMware VMotion is unable to send a Reverse Address Resolution Protocol (RARP) for the tagged guest
virtual machine. For more information VMware Knowledge Base article 2113783.
Workaround: Force an Address Resolution Protocol (ARP) lookup request on the tagged network which generates an
egress traffic that is started from the new switch port and update the switch of the new location. Forcing
an ARP lookup request can be accomplished by performing a ping to another destination on the network
from inside the guest operating system running in the virtual machine.
Systems
affected:
All Dell EMC PowerEdge servers.
