#NetApp DataOnTap and Invoke-NaSysstat

by ucinfo, posted in NetApp, Powershell

So I have been play with the NetApp DataOnTap add in for a while now want to share this.  Essentially all it does is run Invoke-NaSysstat at timed intervals and saves it to an hourly csv file

[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')
$filer   = [Microsoft.VisualBasic.Interaction]::InputBox("Enter the comma seperated filer name", "Enter Filer Name", "")

#Change to match you path
Import-Module E:\PsMON\netapp\DataONTAP.psd1
Connect-NaController $Filer -Credential root

$matrix = @()
$doit = $True

$timer = 10

$LastHour = (Get-Date -format "HH")

while($doit){
  $ThisHour = (Get-Date -format "HH")
  $tSysStat = Invoke-NaSysstat -Count 1 | Select
  $tSysStat
  $matrix += $tSysStat
  If($ThisHour -ne $LastHour){
    $outFile = $filer + "_" + (Get-Date -format "yyyy-MM-dd_HHmm") + ".csv";
    $Matrix | Export-Csv $outFile -NoTypeInformation;$matrix = @();
    "-$outFile-"
  }
  $LastHour = $ThisHour

  For($i=0;$i-le $timer;$i++){Sleep 1 }
}

$outFile = $filer + "_" + (Get-Date -format "yyyy-MM-dd_HHmm") + ".csv";$Matrix | Export-Csv $outFile -NoTypeInformation

Okay so nailed this one eventually.

Please check the SnapManager-SnapDrive Reports and Windows Event Logs for more details.

It was caused by the Cisco ASA firewall on our Inter DC link timing out idle connections after one hour.

When the SME service starts, it establishes a connection over TCP port 810 to other servers in it’s DAG. SME expects the link to be available all the time and not time out.

SME is a but stupid, in that as it EXPECTS the link to be open, and s.

Workaround: Restart the SnapManagerService before the Backups Starts.
Solution#1: Increase the timeout value on the ASA firewalls for port 808 and 810 from 1 hour to8 hours  (we do backups every 6 hours).
Solution#2: Product change to SME, so before it initiates a backup, it actually re-establishes the connection before it starts. BUG/RFE 828920 has been raised to address this.

 

 

NetApp SnapManager for Exchange and Asynchronous call DoSnapshotSet timed out! errors

by ucinfo, posted in Exchange 2010, NetApp

#NetApp #MsExchange

Have some issues with SME backing up Exchange and it throwing “Asynchronous call DoSnapshotSet timed out!” all over the backup log.

Well it appears that having free_space_realloc=on set on the Aggregates caused this.  As soon as it was set to off, this issue went away.

That just leaves this error to be fixed
