Issue/Introduction

Symptoms:
  • The host is configured for all flash vSAN disk groups.
  • Bringup of the host fails when attempting to claim disks for vSAN.
  • You see messages similar to the following in the /opt/vmware/bringup/logs/evosddc-bringup-debug.log file on the CentOS VM, indicating that no disks are being tagged for capacity:

  • You see messages similar to the following in the /scratch/log/capacityflash.log file on the ESXi host:
     
    2018-04-11T16:17:21 [ERROR capacityflash.py::disks_to_tag_capacity_flash::167] More than two SSD types exist
Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.

Cause

The algorithm for determining the capacity disks for an all flash implementation assumes that there will only be disks of two different sizes and types. The smaller disks are expected to be cache disks while the larger disks are expected to be capacity disks. If there are more than two different types or sizes of flash drive in the host, the disks for capacity cannot be determined and no disks will be tagged for capacity. This results in the failure to claim the drives for vSAN disk groups.

Resolution

When configuring an all-flash host for use with VMware Cloud Foundation for Service Providers, ensure that there are no more than two types or sizes of flash drive.
