If you’re managing VMware environments, you might occasionally run into persistent shell warning alerts in your ESXi hosts. Thankfully, you can quickly find and suppress these warnings with a bit of PowerCLI magic.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Check for ESXi Hosts with Shell Warnings<\/h2>\n\n\n\n

Show the actual advanced settings on all hosts. Log into vCenter using PowerCLI and run this command: <\/p>\n\n\n\n

 Get-VMHost | Get-AdvancedSetting | Where-Object { $_.type -eq 'VMHost' -and $_.name -eq 'UserVars.SuppressShellWarning' } | Format-Table entity, name, value<\/code><\/pre>\n\n\n\n
Command output:<\/em><\/p>\n\n\n\n
Entity                Name                          Value\n------                ----                          -----\n...\nfs-vsan-04.int.dc5.cz UserVars.SuppressShellWarning     1\nfs-vsan-05.int.dc5.cz UserVars.SuppressShellWarning     0\n...<\/code><\/pre>\n\n\n\n

Check which ESXi hosts haven\u2019t suppressed the shell warning (default). Then run the following command:<\/p>\n\n\n\n
 Get-VMHost | Get-AdvancedSetting | Where-Object { $_.type -eq 'VMHost' -and $_.name -eq 'UserVars.SuppressShellWarning' -and $_.value -ne 1 } | Format-Table entity, name, value<\/code><\/pre>\n\n\n\n
This command outputs a table listing all hosts where the shell warning hasn\u2019t been suppressed\u2014it remains visible in the GUI.<\/p>\n\n\n\n
Command output:<\/em><\/p>\n\n\n\n
Entity                Name                          Value\n------                ----                          -----\nfs-vsan-05.int.dc5.cz UserVars.SuppressShellWarning     0<\/code><\/pre>\n\n\n\n
Suppress the Shell Warnings<\/h2>\n\n\n\n
Now, to suppress the shell warnings on selected ESXi hosts, run this simple command:<\/p>\n\n\n\n
$esxi=\"fs-vsan-05.int.dc5.cz\"\nGet-VMHost $esxi| Get-AdvancedSetting | Where-Object { $_.type -eq 'VMHost' -and $_.name -eq 'UserVars.SuppressShellWarning' -and $_.value -ne 1 } | Set-AdvancedSetting -Value 1 -Confirm:$false | Format-Table entity, name, value<\/code><\/pre>\n\n\n\n
This command immediately disables the shell warnings on selected hosts. No more alerts in GUI!<\/p>\n\n\n\n
Command output:<\/em><\/p>\n\n\n\n
Entity                Name                          Value\n------                ----                          -----\nfs-vsan-05.int.dc5.cz UserVars.SuppressShellWarning     1<\/code><\/pre>\n\n\n\n
Why (Not) Suppress Shell Warnings?<\/h2>\n\n\n\n
It’s important to note that suppressing shell warnings is only advisable in lab or non-production environments. In production environments, shell warnings provide valuable security reminders. Always keep shell warnings enabled to maintain security awareness unless you’re working in a controlled test environment.<\/strong>
<\/p>\n\n\n\n
Happy scripting!<\/strong><\/p>\n\n\n\n
