Release Notes

PSOD is not seen in the host when the NMI option is
selected in the iDRAC UI
Description: In the iDRAC UI of Dell EMC PowerEdge servers with AMD EPYC processors, below the Configuration
tab, select the Power Control option, and then select NMI(Non-Masing Interrupt). On selecting the
option NMI on the idrac page, the server crashes the PSOD. However, the PSOD is not seen in the yx5x
PowerEdge servers with AMD EPYC processors due to a bug in AMD IOMMU.
Applies to: ESXi 6.5.x
Workaround: Disable IOMMU in the BIOS.

scsi-qla4xxx driver update fails with ESXi 6.0 U3 and
ESXi 6.5.x Dell EMC customized images
Description:
Due to the discrepancy in the driver naming convention for different ESXi releases (for example, 5.x and
6.x), upgrades from ESXi 6.0.x or ESXi 6.5 to ESXi 6.5 U1 A00 retain the older driver for scsi-qla4xxx.
Applies to: ESXi 6.0 U3 and ESXi 6.5.x
Solution: To upgrade to the latest version of scsi-qla4xxx, uninstall the existing driver version using the esxcli
command and install the new driver.
NOTE: If ESXi is booted from SAN network using scsi-qla4xx, the driver cannot be updated.
Virtual machines report guest data consistency errors
after disk extend operation
Description:
Virtual machines running on VMware vSAN 6.6 and later report guest data consistency errors following a
disk extend operation. This is a rare occurrence, requiring specific conditions to be met.
Applies to: ESXi 6.5.x
Workaround:
VMware recommends the following workaround:
1. Log in to the ESXi host through SSH with username as root.
2. To set the Inplace Expansion value to 0, run the following command:
# esxcfg-advcfg -s 0 /VSAN/ClomEnableInplaceExpansion
3. To confirm that the value is set to 0, run the following command:
# esxcfg-advcfg -g /VSAN/ClomEnableInplaceExpansion
4. Repeat this process on all ESXi hosts in the vSAN cluster.
