Storage Template Variables​
The information collected in the Storage template variables defines attributes of the disks available in the system.
The Disks are tracked both by number (0, 1, 2, ...) and by device name (sda, vda, nvme0n1, ...).
For example, if ${Storage/Disks/2/Name} is equal to sda, the the disk model can be retrieved via
both the ${Storage/Disks/2/Model} and the ${Storage/Disks/sda/Model} variables.
note
The tracked disks include also optical disk drives and removable devices (e.g., USB sticks).
