NAIRSATISH — Thu, 05 Jun 2025 05:54:23 GMT

hello!

i am new to powershell and am trying to write a scritp to snapmirror more than 50 volumes using snapmirror, source and destination volumes have been created .Destinations volumes have been restricted.

With some online help i have this scrit to snapmirror volumes but it fails can someone point out the right way to get this done.

Thx

$csv = Import-Csv C:\volume1.csv

$filer1 = "10.168.55.13"

$filer2 = "10.168.55.14"

foreach ($line in $csv) {

Invoke-NaSnapmirrorInitialize -Source $filer1:$line.source -Destination $filer2:$line.dest

}

My csv file looks like this

i get the following error

Invoke-NaSnapmirrorInitialize : Invalid destination @{source=vol1; dest=vol1}.dest: invalid character found in the vol

At C:\Users\xyz\snapmirrortest.ps1:5 char:34

Greetings,

Usually when I run into issues like that it is due to a char at the end of the line in the csv file. you may want to look at the .trim() function to help with the problems. to diagnose if this is your issue you can use the .length() function to see how many chars are in your variables.

Hope this helps

John

One thing you might try is to just look at your variable after the failure. I.e., enter $line.source and that'll show you the value of that variable the last time it was changed. You might find that there's an illegal character in your vol name, which could happen depending on how you generated the .csv to begin with.
