Need to add an if / then statement to a powercli script

I have the following script:

$deadpaths = @()

ForEach ($vmhost in (Get-Datacenter "Operations" | Get-Vmhost | Sort)) { 

$deadpaths += Get-ScsiLun -vmhost $vmhost | `
    
    Get-ScsiLunPath | `
    
        where {$_.State -ne "Dead"} | `
    
    Select @{n="vmhost";e={$vmhost}},ScsiLun,State

}

$ol = New-Object -comObject Outlook.Application
$mail = $ol.CreateItem(0)
$Mail.Recipients.Add("name@mail.com")
$Mail.Subject = "Report"
$Mail.HTMLBody = $($deadpaths | ConvertTo-HTML | Out-String)
$Mail.Send()

Open in new window

I would like to add a if / then that only sends the e-mail out if their are dead paths found. There should be the word Dead in the array generated that I guess could be used to check for content but I am not sure how to use that to create the statement.... any ideas?

To be honest, I'm not familiar with the commands relating to VMs and LUNs in the script above, but it kind of looks like $deadpaths is only added to when state doesn't equal "Dead", which to me says that $deadpaths includes paths that are alive.
Sorry if I've completely misunderstood.  If $deadpaths really does only include dead paths, here's an answer to your question.
$deadpaths = @()

ForEach ($vmhost in (Get-Datacenter "Operations" | Get-Vmhost | Sort)) { 

$deadpaths += Get-ScsiLun -vmhost $vmhost | `
    
    Get-ScsiLunPath | `
    
        where {$_.State -ne "Dead"} | `
    
    Select @{n="vmhost";e={$vmhost}},ScsiLun,State

}
If ( $deadpaths.count -gt 0 ) {
$ol = New-Object -comObject Outlook.Application
$mail = $ol.CreateItem(0)
$Mail.Recipients.Add("name@mail.com")
$Mail.Subject = "Report"
$Mail.HTMLBody = $($deadpaths | ConvertTo-HTML | Out-String)
$Mail.Send()
}

Open in new window

Basically it just checks whether $deadpaths has been added to, and if so sends the email.

Actually now that I think about it the output has one line at the top that might be there regardless if there is any actual output - eg;

vmhost                                      ScsiLun                                                             State

server.domain.net naa.60060e8006d299000000d299000000e9 Dead

server.domain.net naa.60060e8006d299000000d299000000e9 Dead

server.domain.net naa.60060e8005723e000000723e00000057 Dead

Until there is a match, the $deadpaths array should be empty.  Those headers that you see don't exist as an object, they are just properties, and are displayed because of the default behavior of Format-Table, which you could change with the -hideTableHeaders parameter.
