Flash devices used as capacity devices can be unmarked so that they can be used for caching.
process
- To unmark a flash device that has been marked as capacity, run esxcli vsan storage tag remove -d <device name> -t capacityFlash Command. For example, esxcli vsan storage tag remove -t capacityFlash -d mpx.vmhba1:C0:T4:L0 Command, where mpx.vmhba1:C0:T4:L0 Is the device name.
- Verify that the flash device has been unmarked.
- In the output, determine the of the device IsCapacityFlash Property is set to 0
Example: command output
You can run vdq -q -d <device name> Command to verify IsCapacityFlash Properties. For example, run vdq -q -d mpx.vmhba1:C0:T4:L0 The command returns the following output.
[ \{ "Name" : "mpx.vmhba1:C0:T4:L0", "VSANUUID" : "", "State" : "Eligible for use by VSAN", "ChecksumSupport": "0", "Reason" : "None", "IsSSD" : "1", "IsCapacityFlash": "0", "IsPDL" : "0", \},

esxcli information query
esxcli command help information
ssh log in to the VMware ESX server console and query the virtual machine information with the esxcli command. The output format supports normal, xml, csv and keyvalue.
Esxcli is a tool written in python (/ sbin/esxcli.py).
'''use the -- formatter=xml option to output the results in xml format, which is more convenient for program parsing.' '
