Running Sangfor HCI or aSV in a nested environment (VMware Workstation or ESXi) is a great way to build a lab, but storage validation may fail during virtual storage initialization due to virtualization overhead.
If you're deploying a lab or POC environment, the following commands can bypass these checks.
ScenarioCommand
Skip disk performance (IOPS/latency) validationtouch /sf/cfg/vs/.nocheck_slow_disk
Skip SSD lifetime validationtouch /sf/cfg/vs/.nocheck_ssd_lifetime
Restore the default disk performance checkrm -f /sf/cfg/vs/.nocheck_slow_disk
Accessing the CLI

  • Open the host console (physical console or IPMI/iLO).

  • Press Alt + F2 to switch to the Linux shell.

  • Log in as root.

  • Run the required command.

Important
These commands are intended only for lab, training, and POC environments. They disable storage health validations and must not be used in production environments, where disk performance and SSD health checks are critical for system stability and data integrity.
