How to Bypass Sangfor aSV Disk Performance Check for Nested Lab?

Newbie705832 Lv1Posted Jul-31-2025 15:59

Hi all,

I'm trying to deploy Sangfor aSV in a nested VMware lab (ESXi/Workstation) but I'm stuck at the virtual storage provisioning step.

The setup fails because my virtual disks don't pass the minimum IOPS and latency performance check, even though the underlying host storage is a fast SSD and I've already set the required disk.EnableUUID = TRUE parameter on the VM.

Since this is just for a lab, is there a way to disable or bypass this mandatory performance check? I'm looking for a possible CLI command or a hidden setting to force the storage creation.

Thanks for any help.

Enter your mobile phone number and company name for better service. Go

By using the command touch /sf/cfg/vs/.nocheck_slow_disk, you can bypass the mandatory performance checks for your virtual storage provisioning in the Sangfor aSV setup.
Remember to remove the flag after your setup is complete to maintain system integrity. This approach should help you proceed with your lab deployment without being hindered by the performance checks.
