Download Host Patch Rar
IMPORTANT: For clusters using VMware vSAN, you must first upgrade the vCenter Server system. Upgrading only the ESXi hosts is not supported. Before an upgrade, always verify in the VMware Product Interoperability Matrix compatible upgrade paths from earlier versions of ESXi, vCenter Server and vSAN to the current version.

The typical way to apply patches to ESXi hosts is by using the VMware vSphere Update Manager. For details, see the About Installing and Administering VMware vSphere Update Manager. ESXi hosts can be updated by manually downloading the patch ZIP file from VMware Customer Connect. From the Select a Product drop-down menu, select ESXi (Embedded and Installable) and from the Select a Version drop-down menu, select 6.7.0. Install VIBs by using the esxcli software vib update command. Additionally, you can update the system by using the image profile and the esxcli software profile update command.

If the USB device attached to an ESXi host has descriptors that are not compliant with the standard USB specifications, the virtual USB stack might fail to pass through a USB device into a virtual machine. As a result, virtual machines become unresponsive, and you must either power off the virtual machine by using an ESXCLI command, or restart the ESXi host.
When attempting to set a value to false for an advanced option parameter in a host profile, the user interface creates a non-empty string value. Values that are not empty are interpreted as true and the advanced option parameter receives a true value in the host profile.
A rare race condition with static map initialization might cause ESXi hosts to temporarily lose connectivity to vCenter Server after the vSphere Replication appliance powers on. However, the hostd service automatically restarts and the ESXi hosts restore connectivity.
In rare cases, an empty or unset property of a VIM API data array might cause the hostd service to fail. As a result, ESXi hosts lose connectivity to vCenter Server and you must manually reconnect the hosts.
ESXi hosts might intermittently fail with a purple diagnostic screen with an error such as @BlueScreen: VERIFY bora/vmkernel/sched/cpusched.c that suggests a preemption anomaly. However, the VMkernel preemption anomaly detection logic might fail to identify the correct kernel context and show a warning for the wrong context.
If you change the DiskMaxIOSize advanced config option to a lower value, I/Os with large block sizes might get incorrectly split and queue at the PSA path. As a result, ESXi hosts I/O operations might time out and fail.
If you plug in and out a physical NIC in your vCenter Sever system, after the uplink is restored, you still see an alarm in the vSphere Client or the vSphere Web Client that a NIC link on some ESXi hosts is down. The VOBD daemon might not create the event esx.clear.net.redundancy.restored to remove such alarms, which causes the issue.
Rarely, in certain configurations, the shutdown or reboot of ESXi hosts might stop at the step Shutting down device drivers for a long time, in the order of 20 minutes, but the operation eventually completes.
Due to a rare lock rank violation in the vSphere Replication I/O filter, some ESXi hosts might fail with a purple diagnostic screen when vSphere Replication is enabled. You see an error such as VERIFY bora/vmkernel/main/bh.c:978 on the screen.
In particular circumstances, when you power on a virtual machine with a corrupted VMware Tools manifest file, the hostd service might fail. As a result, the ESXi host becomes unresponsive. You can backtrace the issue in the hostd dump file that is usually generated in such cases at the time a VM is powered on.
After a reboot of an ESXi host, encrypted virtual machines might not auto power on even when Autostart is configured with the Start delay option to set a specific start time of the host. The issue affects only encrypted virtual machines due to a delay in the distribution of keys from standard key providers.
When the SLP service is disabled to prevent potential security vulnerabilities, the sfcbd-watchdog service might remain enabled and cause compliance check failures when you perform updates by using a host profile.
In case of temporary connectivity issues, ESXi hosts might not discover devices configured with the VMW_SATP_INV plug-in after connectivity restores, because SCSI commands that fail during the device discovery stage cause an out-of-memory condition for the plug-in.
In some cases, MAC learning does not work as expected and affects some virtual machine operations. For example, cloning a VM with the same MAC address on a different VLAN causes a traffic flood to the cloned VM in the ESXi host where the original VM is present.
An abrupt power cycling or reboot of an ESX host might cause a race between subsequent journal replays because other hosts might try to access the same resources. If a race condition happens, the journal replay cannot complete. As a result, virtual machines on a VMFS6 datastore become inaccessible or any operations running on the VMs fail or stop.
When a vSAN host has memory pressure, adding disks to a disk group might cause failure of the memory block attributes (blkAttr) component initialization. Without the blkAttr component, commit and flush tasks stop, which causes log entries to build up in the SSD and eventually cause а congestion. As a result, a NMI failure might occur due to the CPU load for processing the large number of log entries.
In some cases, the host designated as the leader cannot send heartbeat messages to other hosts in a large vSAN cluster. This issue occurs when the leader uses an insufficient size of the TX buffer. The result is that new hosts cannot join the cluster with large cluster support (up to 64 hosts) enabled.
Due to a dependency between the management of virtual RAM and virtual NVDIMM within a virtual machine, excessive access to the virtual NVDIMM device might lead to a lock spinout while accessing virtual RAM and cause the ESXi host to fail with a purple diagnostic screen. In the backtrace, you see the following: SP_WaitLock SPLockWork AsyncRemapPrepareRemapListVM AsyncRemap_AddOrRemapVM LPageSelectLPageToDefrag VmAssistantProcessTasks
When you enable Latency Sensitivity on virtual machines, some threads of the Likewise Service Manager (lwsmd), which sets CPU affinity explicitly, might compete for CPU resources on such virtual machines. As a result, you might see the ESXi host and the hostd service to become unresponsive.
When vSphere Replication is enabled on a virtual machine, you might see higher datastore and in-guest latencies that in certain cases might lead to ESXi hosts becoming unresponsive to vCenter Server. The increased latency comes from vSphere Replication computing MD5 checksums on the I/O completion path, which delays all other I/Os.
If you plug in and out a physical NIC in your vCenter Sever system, after the uplink is restored, you still see an alarm in the vmkernel.log of some ESXi hosts that a NIC link is down. The VOBD daemon might not create the event esx.clear.net.redundancy.restored to remove such alarms, which causes the issue. 041b061a72
