Unable to send a notification email from Alarm action if multiple emails are separated by semicolon in VCSA 6.5 (2150106)

  • 1 Ratings


When an alarm action is set up using PowerCLI to send notification emails to multiple email addresses, the emails are not sent to the expected recipients when the alarm gets triggered in vCenter Server Appliance.


When setting up multiple emails to alarm action using PowerCLI, the emails are added to the "To" field semicolon (;) as separator by default. However, VMware vCenter Server Appliance (VCSA) 6.5 only accepts comma (,) as separator and that causes the emails not to be sent successfully.


To resolve this issue:
  1. Replace semicolon (;) with comma (,) manually in vCenter alarms action configuration. Email alarm notifications will be sent successfully.
  2. Set an individual alarm action for every individual email using the following sample script:

    $emails = @('', '' )
    foreach ($email in $emails)
    Get-AlarmDefinition -Name "Storage DRS recommendation" | New-AlarmAction -Email -To $email
