Greetings,
The attached powershell script checks the volumes of your 7-mode systems and create a list of volumes which didn't take a snapshot yesterday in a xls format then sending as an email.
I am assuming that the snapshot name is hourly.0 and for snapvault, snapvault_hourly.0 you can change them to your naming convent here : -
$snapName = "hourly.0"
$vaultSnap = "snapvault_hourly.0"
Create a txt file containing the list of your 7-mode systems and put it on the same location as the script. The file name should be : -
$netappFile = "7netapp.txt"
In case you want to exclude few volumes form the script, create a file and name it Ignore.txt and add the volumes there, one in each line : -
Select-String -Path "Ignore.txt" -CaseSensitive -Pattern "^$($_.Name)$"
The below portion is for sending an email with the list, you can modify it to has the emails you want : -
#Send the output as an attachment
$smtpTo = "email1@domain.com, email2@domain.com"
$smtpServer = "exchange.domain.com"
$smtpFrom = "SnapShotsScript@domain.com"
$messageSubject = "SnapShots Script (7-Mode)"
#create new message to send
$message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto
$message.Subject = $messageSubject
$message.ReplyTo = $smtpTo
$message.IsBodyHTML = $true
$message.Attachments.Add($outputFile)
#define message body
$message.Body = “Attached is a list of volumes which didn't take a snapshot last night.”
#send the message
$smtp = New-Object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($message)
$message.Dispose()
Below is the full script : -
Clear
# the reference time which we want to have a snapshot taken at
# this will return an object referencing yesterday and named hourly.0 or snapvault_hourly.0
$refTime = [DateTime]::Today.AddDays(-1)
$snapName = "hourly.0"
$vaultSnap = "snapvault_hourly.0"
$outputFile = "No Snapshots.xls"
Out-File $outputFile
#Getting Netapp Filers List from a file called 7netapp.txt
$netappFile = "7netapp.txt"
$netappList = Get-Content $netappFile
foreach ($netapp in $netappList){
Write-Host -ForegroundColor Yellow "`nConnecting to $netapp"
Add-Content $outputFile "`n***********************"
Add-Content $outputFile $netapp
try{
Connect-NaController $netapp -RPC
Add-Content $outputFile "***********************"

Write-Host -ForegroundColor Magenta "Ignoring volume $($_.Name) as it is part of the ignore list"
}
# get snapshots for the volume which match the references
elseif ( ($_ | Get-NaSnapshot | Where-Object { $_.AccessTimeDT -gt $refTime -and ($_.Name -eq $snapName -or $_.Name -eq $vaultSnap) }).count -ne 1) {

Add-Content $outputFile $_.Name
}

}
}
