WFA Volume resize, TargetSize concats in place of sum

francoisbnc — Wed, 07 Sep 2016 13:22:29 GMT

I would like summarize actual vol size of a volume with an added value

TargetSize : createvolumebin.size_mb + $addedsizebin

unfortunately that join rather summarize, I saw type is [capacity].

Is that a way to perform arithmetic operation in this field?

You can't do arithmetic addition in the field directly. The + operator works as concatentation there. You can utilize a function, though, to do the match for you. I created this function:

def AddValues(num1, num2)
{
num1 = (float)(num1);
num2 = (float)(num2);
return (num1 + num2);
}

It forces each number to a floating point number and them adds them together and returns the value. In this case, you would put this in the TargetSize field:

TargetSize : AddValues(createvolumebin.size_mb, $addedsizebin)

Good luck!

Strange thing

this works:

(((long)createvolumebin.size_mb) + ((long)($volsizebin)))

this not:

(((long)createvolumebin.size_mb) + ((long)($volsizebin *1024)))

Anyway, it works well with your solution thanks

Brian, where did you add the function you created? Inside the PowerShell or Perl code for the 'resize volume' command?

francoisbnc, what version of WFA were you using for (((long)createvolumebin.size_mb) + ((long)($volsizebin)))?

I'm using version 5 and getting illegal expression.
