(EVFS Software Required)
For a whole disk (physical) volume in file-level encryption mode, the command would be:
% evfsadm map -f /dev/dsk/c1t0d0
The following command will delete the EVFS device special file
/dev/evfs/vg01/lvol1
and remove
its entry from the kernel registry (if EVFS is enabled for
/dev/evfs/vg01/lvol1
, this command will
fail):
% evfsadm unmap /dev/evfs/vg01/lvol1
The following command will shut down the EVFS subsystem if all EVFS volumes are disabled:
% evfsadm stop
The following command will display encryption statistics about all EVFS volumes:
% evfsadm stat -a
The above command produces the following report:
----- EVFS statistics -----
Total EVFS Volumes: 2
EVFS Subsystem Status: up
Active Encryption Threads: 2

Fields are defined as follows:
Total EVFS Volumes
Total number of EVFS volumes in the kernel registry.
EVFS Subsystem Status
Status of the EVFS kernel components (up or down).
Active Encryption Threads
Number of EVFS kernel threads for cryptography processing.
EVFS Volume Name
Name of the EVFS volume.
State State of the EVFS volume, where EFS volume indicates it is in file-level encryption
mode. For volume-level encryption mode, enabled indicates it is enabled for
encrypted/decrypted access, disabled indicates all access is disabled, and raw indicates
it is open for raw access.
orr Number of queued (outstanding) read requests.
owr Number of queued (outstanding) write requests.
odr Number of queued (outstanding) decryption requests.
oer Number of queued (outstanding) encryption requests.
bpr Number of data blocks read.
bpw Number of data blocks written.
bpd Number of data blocks decrypted.
