The following are descriptions of some Disk Information panel items:
● Power On Hours – Total number of hours that the disk has been powered on since it was manufactured. This value is
updated in 30-minute increments.
● FDE State – FDE state of the disk. For more information about FDE states, see the Dell EMC PowerVault ME4 Series
Storage System CLI Guide.
● FDE lock keys – FDE lock keys are generated from the FDE passphrase and manage locking and unlocking the FDE-capable
disks in the system. Clearing the lock keys and power cycling the system denies access to data on the disks.
Rear view
The Rear tab shows the rear of all enclosures in a graphical view.
The rear view shows enclosure IDs and the presence or absence of power supplies, controller modules, and expansion modules.
It also shows controller module IDs, host port types and names, network port IP addresses, and expansion port names.
To see more information, hover the cursor over an enclosure ear or a component. To illuminate a locator LED for any of
the components, select one or more components and click Turn On LEDs. To turn off individual locator LEDs, select the
components and click Turn Off LEDs. To turn off all locator LEDs, ensure that no components are selected and click Turn Off
LEDs. For a 5U84 enclosure, only enclosures, I/O modules, and disks are selectable.
NOTE: Protocol-specific properties are displayed only for host ports that use those protocols.
