Release Notes

By default, VMFS datastore is disabled on Dell EMC
14
th
generation PowerEdge Servers with factory-
installed VMware ESXi on BOSS-S1
Description: The Dell EMC 14
th
generation servers installed with ESXi on the BOSS-S1 device do not have VMFS
datastore enabled by default.
Applies to: ESXi 6.5.x and later, 14
th
generation PowerEdge Servers, and BOSS-S1
Workaround: Dell EMC recommends using the BOSS-S1 device as a boot device only for VMware ESXi. For more
information, see the VMware Knowledge Base article 2145210.
Scratch partition stops working after hardware or
software iSCSI is enabled on ESXi with elxiscsi
Emulex driver
Description:
When specific versions of elxiscsi Emulex driver are installed or is part of ESXi, then, enabling the
hardware or software iSCSI stops the scratch partition to work. This prevents the redirection of logging
to a persistent data store causing loss of log data across reboots.
Applies to: ESXi 6.5.x
Solution: Dell EMC recommends that you install ESXi 6.5U1-A05 customized image which has latest Emulex
elxiscsi-11.2.1197.17 driver to resolve this issue.
Perform one of the following steps:
● Use syslog for logging on hardware or software iSCSI configurations with Emulex driver version
elxiscsi-11.2.1152.0 and later. For more information about configuring syslog, see VMware
Knowledge Base article 2003322.
● Uninstall the elxiscsi driver and the associated shared library elx-esx-libelxima.so, if Emulex is
not part of the configuration. To uninstall the elxiscsi driver, run the following commands:
1. /etc/init.d/hostd stop
2.
localcli software vib remove -n elxiscsi -n elx-esx-libelxima.so
3. reboot
Virtual machines fail to power on, when system BIOS
has MMIO set to 56 TB with supported GPU
configured as pass-through device
Description:
When system BIOS has Memory Mapped I/O Base set to 56 TB and if the server has GPU cards such
as Nvidia M60 as the PCIe pass-through device, the virtual machines fails to power on.
Applies to: ESXi 6.5.x and Dell EMC's 14
th
generation PowerEdge Servers
Workaround: In System BIOS Settings > Integrated Devices, set Memory Mapped I/O Base to 12 TB. For more
information, see the VMware Knowledge Base article 2142307.
