Good ideal but seems to not take the case of the VM name into account. If the name inside vcenter is SERVER1 in upper case entering server1 into the check name field returns the server does not exist check.

Is there a way to take case into account as well?

[Orf Gelbrich]

If you open up the custom task the if/compare would have to change

But I am wondering since the custom task is looking at a screen in UCSD how the name shows up in the UCSD screen.

Do you have a log section where it should find it amongst your VM’s and it is not.

Hit submit to quick?

In the custom task this line(72)

if ( new java.lang.String(hostname).equals(new java.lang.String(Name)) )

Would have to be replaced with something like from this posting

https://stackoverflow.com/questions/2140627/javascript-case-insensitive-string-comparison

you would have to make sure the strings are either converted to upper or lower case..

UCSD is case sensitive – it is linux.

I ended up using your Case Sensitive / Insensitive workflow (#359) with an IfElse looking for the VMsFound == “1” condition. Works great using that RegExFilter.

I wanted something to check the name prior to starting the VM provisioning instead of just the generic error.

thanks

In UCSD 6.6 we are getting Bash/Python/javascript workflow form pre processing checking. Meaning you fill out the form and it will check when you hit submit but before the workflow runs. UCSD 6.6 will be out by March 31. ☺

[Somersbd99]

That is good news, something that is definitely needed. Is 6.6 still on track for release?

thanks
