Hi,
We have a Dell FX2 blade server. It has 3 host. First 2 host only have SD cards where esxi is installed and its datastores are using the storage of the blade each with 8TB. The third host has SD card with the esxi installed and 2 internal 200GB SSD. First drive is where the vcenter installed and the 2nd drive is where the vsan witness.
I'm trying to unmount/delete the datastores on both Host 1 and Host 2 in order for me to add those datastores on the vsan storage but for some reason it keeps saying that datastore is being used. Here are the things I've done so far
1. disabled swap and host cache
2. disabled HA
3. set both datastores on maintenance mode
4. ensured no vm's inside
5. disabled Storage I/O control
6. removed from cluster
Not sure what else do I need to do?
Thanks
Jeff
