Able to set IOPS with "knife vsphere vm vmdk add"?

[petericebear]

Hi,

Is it possible to set the IOPS of a new vmdk on attachment to a VM?
We have SSD, Block and Archive which we want to limit IOPS based on the datastore it goed to.

Thanks in advance, for reply

We don't expose that directly. Would need to look up where in the API this gets set. might be able to do it through knife vsphere vm config...

Which version of vsphere is this for?

[petericebear]

That is for version 5.5, but going to upgrade to 6.5 soon. Would be great if that it is possible :D

Do you have an idea how to set this, at which level?

I couldn't find anything about iops. There was some stuff about disk shares (SharesInfo) but I'm not clear if that translates into iops. I think the easiest way to find it is to set it in the web UI and then try and find it in a console session. Just haven't had the time this week -- my day just just changed into our busy period.

It should be possible:

In this PowerShell script the setting can be set. I will look into this, and will give you an update.

This gist works now for setting IOPS. Will try to make a PR for it this week some where.

Aha, good find. Same comment as the other one -- did you want to PR that after switching to SearchHelpers and ui.info?

Or let me know if you want me to do it; just wanted to make sure you have the opportunity for the credit in the commit log.

Yeah will do, think at the end of the week I have some time for that
