Script to list snapshot copies of all volumes

justin_smith

Im looking for a script that will give me the snapshot copies names, date/time, size, etc for each individual volume on a filer.

Preferably I'd like something exported to excel that would show me:

Volume Name

     Snapshot copy name

     Snapshot copy name

Based on the screen shot the output would be this:

testSM

     hourly.0   

     hourly.1

     nightly.0

     hourly.2

Etc....

Doable?

sorry about that syntax for the cdot is slightly different.

This should do it for you.

Import-Module dataontap

Connect-NaController [filer] -Credential root

get-navol|get-nasnapshot|Export-Csv mysnapshots.csv

Justin,

One way to do this is with the data ontap powershell toolkit

Import-Module dataontap

Connect-NcController Mycluster or

          connect-nacontroller filer

Get-NcSnapshot|Export-Csv mysnapshots.csv  or

           Get-NaSnapshot|Export-Csv mysnapshots.csv

You could also limit down the output by specifiy the volume or the svm(vserver) volume name pattern.

Im familiar with the OnTap toolkit.

It doesnt like the Get-NcSnapshot command:

Get-NcSnapshot : Value cannot be null.

Parameter name: Controller parameter neither specified nor set in $global:CurrentNcController

Here's my script:

Import-Module dataontap

Connect-nacontroller REALFILERNAME -Credential jsmith

Get-NcSnapshot|Export-Csv mysnapshots.csv

justin_smith

Looks like thats a cluster mode command?

I think Im figuring it out, Im using the get-nasnapshot command which is for 7 mode. The only thing is, I need it to grab ALL volumes.

Import-Module dataontap

Connect-nacontroller REALFILERNAME -Credential jsmith

Get-NaSnapshot|Export-Csv 'H:\NetApp Scripts\snapshots.csv'

What happens is it asks me for a TargetName for the volumes.

That seemed to work....

Only thing is it gives me the info bassackwards.

Is there a way to get the TargetName on the first column of the spreadsheet?

olson

Your welcome!

You can format the output with the select command.

get-navol|get-nasnapshot |select TargetName,name,Created|Export-Csv mysnapshots.csv

You can select any of the rows in the header.

Thanks, that worked too... last question.

Here's my current script:

Import-Module dataontap

$Controller = @('filername')

Foreach ($filer in $controller)

{

Connect-nacontroller $filer -Credential jsmith

get-navol | get-nasnapshot | select TargetName,name,Created | Export-Csv 'H:\NetApp Scripts\$filer.snapshots.csv'

}

Im looking for it to save the file with the filername.snapshot. I've tried filername_snapshot and filername.snapshot, but it only gives it the $filer.snapshot name.....

Hi justin_smith 

 

 

Could you please let me know how you have saved file "filername' for command $Controller = @('filername').

 

If possible could you please share script as well

Hello @Neal1703,

 

He is simply using "filername" as a place holder here.  The "@()" turns it into an array so that  if there are multiple the bits of script below can loop over them.

 

$Controller = @('myNetApp.local.com', 'myOtherNetApp.local.com', 'myDRNetApp.remove.com')

 

@justin_smith,

 

You asked:  "m looking for it to save the file with the filername.snapshot. I've tried filername_snapshot and filername.snapshot, but it only gives it the $filer.snapshot name....."  You're seeing that behavior because of the single quotes around the value.  If you replace with double quotes it should work...

 

Get-NaVol | Get-NaSnapshot | select TargetName,name,Created | Export-Csv "H:\NetApp Scripts\$($filer).snapshots.csv"

 

If you're curious, there is a lot of information about variable expansion in string output here.

 

Hope that helps.

I need script for deleting snapshot more than 32 days in the cluster in CMode.

You should start a new topic to get the best visibility.  With that being said, this should work for you:

 

Get-NcSnapshot | ?{ $_.Created -lt (Get-Date).AddDays(-33) }

Hope that helps.
