My example does not display naa.xxxxxxxxx because it is a boot from a USB disk.

Open SSH ESXi Session
Execute this command: ls -l / where the output:
Use your ID Disk with this command:
vmkfstools -P /vmfs/volumes/d408f6e7-974ffb48-05bd-73467ca990f1
The output is similar at this if use USB for boot:
For the last check use command esxcfg-mpath -b for identity the USB disk:
If after the command vmkfstools -P ........ the output is similar at this:
the boot is from SAN

+when i try "vmkfstools" it show to me:

+but when try "esxcfg-mpath -b" show to me:

From first command show to me as SAN because show "nna.." but the second command show to me "local disk"?

Last command esxcfg-scsidevs -a and post the output.
Do you have ISCSI, DAC or Fibre connection to external disk?
we have local disk on server, and we have FC for SAN
