hi experts, i have a doubt, how do i know which storage is connected to my esxi hosts san or nas.
how do i confirm i am using san or nas
Maybe you can just post a screenshot of your "datastore" overview here.
There you can see "NFS" or "iSCSI" oder "FC"
Use this command line from your esxi Host.
# esxcli storage core device list
You can add -d option at the end if you want look at a specific Datastore.
# esxcli storage core device list -d naa.6589cfc000000b7a93e8244d1c7106b7
