The following procedure will help you view all the storage devices seen by an ESXi host:
- Log in to the vCenter Server using the vSphere web client and use the key combination Ctrl + Alt + 2 to bring up the hosts and clusters inventory view, as shown.
- Select the desired host and navigate to Configure | Storage Devices to view all the LUN devices seen by the ESXi host. The LUN devices could be local or remote storage (FC, iSCSI, NAS, FCoE):
Alternatively, you can issue the commands esxcfg-scsidevs -u and esxcli storage core device list at the ESXi CLI to list the storage devices.
