first script

JSHACHER11 — Thu, 05 Jun 2025 06:05:21 GMT

Hi guys,

I started playing with powershell this week - I've tried to run the following but getting this:

"the size of the volume is DataONTAP.Types.Volume.SizeInfo"

the script is:

Import-Module dataontap

$filername = Read-Host 'What is the filer hostname?'

$name = Read-Host 'What is your username?'

Connect-NaController -Name $filername -Credential $name

$volname = Read-Host 'What is the volume name?'

$volsize = Get-NaVolSize -Name $volname

Write-Host "the size of the volume is:" $volsize

my debugger is saying that my problem is in this line:

$volsize = Get-NaVolSize -Name $volname

Thank you

Make sure you set your execution policy to unrestricted.

Is your storage controller joined to the domain? If so, then is your domain account (logged on with) a member of the storage controllers administrator's group?

If yes, then:

Import-Module dataontap

$filername = Read-Host "What is the filer hostname?"

Connect-NaController -Name $filername | out-null

$volname = Read-Host "What is the volume name (case sensitive)?"

$volsize = Get-NaVolSize $volname

Write-Host "The size of the volume is:"$volsize.volumesize

If no, then:

Import-Module dataontap

$filername = Read-Host "What is the filer hostname?"

Connect-NaController -Name $filername -Credential (get-credential) | out-null

$volname = Read-Host "What is the volume name (case sensitive)?"

$volsize = Get-NaVolSize $volname

Write-Host "The size of the volume is:"$volsize.volumesize

no go

Thanks though

Hello,

In the below scriptlet you are connecting to the controller only with username, you are not entering the password

$name = Read-Host 'What is your username?'

Connect-NaController -Name $filername -Credential $name

Try with the below method

$name = Read-Host 'What is your username?'

$password = Read-Host 'What is your Password?'

$ControllerPassword = ConvertTo-SecureString -String $password -AsPlainText -force

$credential = New-Object System.Management.Automation.PsCredential($name,$ControllerPassword)

Connect-NaController -Name $filername -Credential $credential

this line (Connect-NaController -Name $filername -Credential $name) brings up a popup that asks for a password. I insert the password and the script moves on

Again, my debugger is pointing to this line:

$volsize = Get-NaVolSize -Name $volname

Thank you

what are you giving as input to $volume, can you share an example?

Here's the output when i ran your set of cmdlets.

I've tried with a volume I created, called vol7 and also with vol0

I am late to the discussion, but this is working for me:

Import-Module dataontap

$filername = Read-Host 'What is the filer hostname?'

$name = Read-Host 'What is your username?'

Connect-NaController -Name $filername -Credential $name

$volname = Read-Host 'What is the volume name?'

$volsize = Get-NaVolSize -Name $volname

Write-Host "the size of the volume is:" ($volsize).volumesize

What is the error that the debugger is throwing out?

Scott,

I am getting this:

"the size of the volume is DataONTAP.Types.Volume.SizeInfo"

The only difference between my script and yours is this:

mine:

Write-Host "the size of the volume is:" $volsize

yours:

Write-Host "the size of the volume is:" ($volsize).volumesize

(is that my issue?)

I would have to try that again with your line

I'll let you know

Thanks

Yep, you need to call the property(volumesize) of the object ($volsize). Otherwise it simply returns the object type, not the usable information of the object.

sweet

I'll try that and let you know

Works!

Thanks Scott

Can we take it a step further?

- How do I list all volumes (just volume names) and Read-Host "pick a volume from the list to show its size"

- If the input volume name does not exist, can we display a message >> "volume doe not exist, try again"

Cheers

Joel, I am in training, but I have attached a script here that does the same sort of thing for finding CIFS shares and setting the browse/nobrowse option. I have added some notes to it, but I should be able to work with it to do this for volumes sometime next week(should be pretty simple).

Also for the write-output, that comes out in bytes, an easy format option is to use write-output ($volsize).volumesize |convertto-formattednumber -type datasize

Here ya go! Since the user selects by number, there shouldn't be mistakes in vol name. The script retains the check to make sure the user is entering a number, but now returns a human readable formatted vol size. (Got bored at lunch)

I have to wonder--is there any reason NetApp implements the ToString method on this object to output the object type name as a string instead of the volumesize integer itself?

Re: first script

cscott — Thu, 25 Apr 2013 18:59:06 GMT

I cannot say on authority, but powershell is object oriented, therefore in this context the request is for an object that is being called back into a variable. Now $volsize is an object, to get that object's information, you have to reference the property . The property of variable/object $volsize is the output, and in order to conform to proper syntax and compatibility it should be required to call (object).property. Otherwise you end up with no idea of how one output should be called in reference to another. By that what I mean is what object only has one property and therefore will output a single property as int/str/arr, etc? You could not expect to write anything with any certainty because the rule could change for every single output, now multiply that by every vendor doing it their own way, gets to be a mess very quickly.

If you run get-navolsize -name vol0, you get a default output which is a header, separator, and the output integer.

Scott, what does this line do? >> $volList = @($volList)
