Copy space allocation different RAID to what was provisioned

[slink]

I setup a VV on a RAID1 CPG and set the virtual copy to be on a RAID6 NL CPG however when I look at the settings for the VV the provisioning shows the correct RAID6 CPG but the allocation is all coming from RADI1 on my FC disks. How/why is this happening?

What do the settings on your NL_r6_virtualcopy CPG look like?

like this

Roger that, do you have any snaps yet that would use the Raid6 space?

Can you use command line/ssh to do a:

showvv -r Hyper-V_CSV3

Its should break out the capacity in detail like this:

-----------------------------(MB)-----------------------------

Thanks for helping me out with this. Yes I have snapshots for this VV being created. I noticed it on a CSV1 but I thought that was because I had originally set the snapshot CPG on the VV to be a RAID1 volume and then moved it to a RAID6 one so I thought it was an issue with the base snapshot being on RAID1 and not being able to be moved. But CSV3 I setup with the virtual copy CPG being the RAID6 right from the start but the VVs are still being created on RAID1 as pictured but I don't know how or why.

Here's the output from that command:

Good news, this looks like it might be a typo in the GUI. I am pretty sure that is suppose to be your ADMIN space, not copy space.

Here is what I see:

OK, that seems a bit weird though. Here's a different VV showing what I would expect:



But I think you are right, because in this view I can see the virtualcopy space is being taken from the RAID6 CPG so guess it's just a bug:

[Richard Siemers]

What version of the IMC are you using?

[trireed]

Are you using AO ? If so its possible it moved some hot Snap regions into the FC space. If your Snap space is part of AO then that is where I believe the confusion is.

I'm using IMC Version 4.3.0.71. Maybe I should upgrade it.

Haven't enabled AO yet. Not sure I want to while I have lots of FC disk available.
