Each time a VMware Composer starts to create or delete of linked-clone desktops (100-150 VMs), the following error messages are logged in the serve

“The status of the PCIe disk at location NVMe Drive Port 1A Box 1 Bay 1 is Degraded” “Temperature exceeded on PCIe disk NVMe Drive Port 1A Box 1 Bay 1” However, the ESXi server does not show any such errors and everything from the ESXi side looks good.

Hi Tyagirr0063

This doesn't look to a problem on horizon side. First try to isolate the issue outside horizon, what if you clone a VM directly in vCenter on same host and datastore that you have defined under horizon desktop pool?

If this also fails, it means the issue lies at vcenter/host/hardware level. During a cloning process please keep a track of events under vSphere Web Client > vCenter Server > Cluster > Host > Monitor > Events and we need to proceed accordingly. You can share a snippet of events here as well.
