Apo volumes

Some of the users not able to see the applications which is stacked through app volume they are assigned to 16 applications does this cause the issue?

If you have >15 packages mounted, you need to add a second SCSI Controller to mount another 15 packages.

Make this change to your Gold Image and then re-provision your pools.

Make sure your SCSI Type is VMware Paravirtual.

Is this documented somewhere?

Hello,

Quick fix would be: 

* Add 4 scsi controllers on the base image. take a  new snapshot 

* Publish to pool. 

* This should avoid the issue you are facing for hot-add of scsi controller. So vCenter can use the existing scsi controllers when request received from app volumes

Thanks for providing below solution

Is there any other solution for the issue, since we are not using SCSI paravirtual type

Hello 

The suggestion i have shared only applies to LSI SAS not for paravirtual.

Second/alternate solution: You could try adding devices.hotplug=true parameter on base image advanced settings option.

Procedure to add this parameter is in this kb :https://kb.vmware.com/s/article/1012225

You just need to add 1 or 2 more SCSI Controllers to fix your AppVol mounting issue.

But I would suggest you look at getting to SCSI paravirtual to better your performance.
