vCenter Server - Host Profiles error "the option uservars.suppressShellWarning"

Receive the error "the option uservars.suppressShellWarning"

This is due to a previous selection to suppress warnings for instance for enable SSH on your ESXi host.

Solution:

To fix this you can either change the host profile to enable this suppression

Advanced Configuration Settings -> Advanced Options -> Advanced configuration option
Click the green plus "+" sign symbol to create a new option.
Select advanced option "configured a fixed option"
The name of the option "UserVars.SuppressShellWarning"
Set the value to "1"

vCenter Server - Host Profiles - set NTP

Setting your host with NTP services using host profiles requires a few changes to be made in different settings on host profiles.

Solution:

Edit the host profile

• Lets first set the NTP servers:
• General system settings -> Date and Time configuration
• Click Date and time configuration
• Time settings - "Configure a fixed NTP configuration"
• List of time servers - add server IP address or FQDN for NTP servers.  Use comma to list multiple servers
• Now lets enable the NTP service:
• Security and services -> Services configuration -> Services configuration
• Select NTPD (make sure this is enabled)
• On service verify the dropdown box is set to "Establish a fixed service configuration"
• Policy that dictates how the service will be handled - type "on"
• Now lets set the firewall rule:
• Security and services -> Firewall configuration ->  Firewall configuration -> Ruleset Configuration
• Select ntpClient (make sure this is enabled)
• Verify dropdown "Specify the configuration of a fixed ruleset.
• Check the box for enabled  on "Flag indication where ruleset should be enabled"
• Check the box for enabled on "Flag indication where ruleset should allow all ip addresses"  (this is self explanatory)

vCenter server - host profiles error "host state doesn't match specification..."

Setup host profiles and when applied on other hosts i get receive the error message:

Seems that ESXi treats SAS disk as shared disks instead of local disks which causes these errors when you create your host profile from an existing ESXi host.

Solution:

The only workaround I found is to disable the following settings in the host profile -

• Storage configuration - > Pluggable Storage Architecture (PSA) configuration
• disable "PSA device settings"
• disable "PSA device configuration"
• Storage configuration -> Native Multi-Pathing NMP
• disable "PSP and SATP configuration for NMP devices
