Table 10. Activity progress properties and values
Property Value
Time The date and time of the latest status update.
Seconds The number of seconds this component has been active.
Component The name of the object being processed.
Status The status of the component representing its progress/completion state.
○ ACTIVE – The operation for this component is currently active and in progress.
○ OK – The operation for this component completed successfully and is now inactive.
○ N/A – The operation for this component was not completed because it was not
applicable.
○ ERROR – The operation for this component failed with an error (see code and
message).
Code A numeric code indicating the status.
○ 0 – The operation for this component completed with a “completed successfully”
status.
○ 1 – The operation for this component was not attempted because it is not applicable
(the component doesn’t exist or doesn’t need updating).
○ 2 – The operation is in progress. The other properties will indicate the progress item
(message, current, total, percent).
○ 10 or higher – The operation for this component completed with a failure. The code
and message indicate the reason for the error.
Message A textual message indicating the progress status or error condition.
Changing FDE settings
In the Full Disk Encryption panel, you can change settings for these options:
● FDE general configuration
○ Set the passphrase
○ Clear lock keys
○ Secure the system
○ Repurpose the system
● Repurpose disks
● Set import lock key IDs
Changing FDE general configuration
CAUTION:
Do not change FDE configuration settings while running I/O. Temporary data unavailability may
result. Also, the intended configuration change might not take effect.
Setting the passphrase
You can set the FDE passphrase the system uses to write to and read from FDE-capable disks. From the passphrase, the system
generates the lock key ID that is used to secure the FDE-capable disks. If the passphrase for a system is different from the
passphrase associated with a disk, the system cannot access data on the disks.
NOTE: Be sure to record the passphrase as it cannot be recovered if lost.
Set or change the passphrase
Perform the following steps to set the passphrase:
1. In the System topic, select Action > Full Disk Encryption.
