With the Operations Manager Reports you can manually work out what snapshot is used to create the clone. As far as I'm aware the only way (other than trawling the messages file) to find out when a clone was created is by finding out what snapshot it used in the parent volume. That is normally what is most important as the clone locks the source snapshot.
I would try using Powershell if you're a Windows house, or shell script via ssh/rsh.
The ONTAP Powershell Toolkit provides the necessary module to be added to Windows Powershell. Have a look here:- https://communities.netapp.com/docs/DOC-6162
I've been meaning to put a script together to do this also, so now you've motivated me to do it. This is a basic example, and only shows vol clones (need to work on it a bit more to do LUN clones):
---------------------------------------------------snip----------------------------------------------
Import-Module DataONTAP
$controller=$args[0]
connect-nacontroller $controller | Out-Null
$snapshots=get-navol | get-nasnapshot | where-object {$_.Dependency -like "*vclone*"}
# Search for Snapshots which are locked by clones
if ( $snapshots ) {
ForEach ($snap in $snapshots)
{
$CloneVol = get-navol | where-object {$_.CloneParent -like $snap.TargetName}
ForEach ($vol in $CloneVol) {
$Clone = New-Object PSObject -Property @{
CloneType = 'Vol'
CloneVolumeName = $vol.Name
Created = $snap.Created
ParentSnapshot = $snap.Name
ParentVolume = $snap.TargetName
ParentLun = '' }
$Clones += $Clone
}
}
Return $Clones
}
else {
write-host "No Clones Found on $controller"
}
---------------------------------------------------snip----------------------------------------------
Call the script with the filer name as a command line argument. Looks like this:
PS L:\WindowsPowerShell> .\CloneList.ps1 toaster1
ParentVolume : ORA_DB_01
ParentLun :
ParentSnapshot : smo_orasid_orasid_orahost_20120306082215_f_h_1_8ae6768345g24560135e719f4270001_0
CloneVolumeName : SnapManager_20120306083548285_ORA_DB_01
CloneType : Vol
Created : 06/03/2012 08:23:51
PS L:\WindowsPowerShell>
So the 'Created' date is the timestamp from the source snapshot used for the volume clone.
Hope that helps!!
