Issue/Introduction

Symptoms:
Disks are not claimed for the VSAN capacity tier during VMware Cloud Foundation bring-up

Environment

VMware Cloud Foundation 3.0.x

Resolution

This is a known issue affecting VMware Cloud Foundation 3.0.x. There is currently no resolution.

Workaround:
To workaround this issue, disks can be manually marked as available for the VSAN capacity tier.

On each ESXi host, the esxcli storage core device list and esxcli vsan storage tag add -d <device> -t capacityFlash commands can be used to mark individual disks for the VSAN capacity tier.

A script similar to the following can be used to mark disks for the VSAN capacity tier based on their size:

 
esxcli storage core device list | grep -B 3 -e "Size: 3662830" | grep ^naa > /tmp/capacitydisks
for i in `cat /tmp/capacitydisks`
do
esxcli vsan storage tag add -d $i -t capacityFlash
vdq -q -d $i
done

Note: The Size value should be replaced with the actual size of the disks to be used in the VSAN capacity tier (as returned by the esxcli storage core device list command). Other unique parameters returned by the esxcli storage core device list command can also be used to identify disks for the VSAN capacity tier.
