Encrypted Volume and File System v1.1 Administrator's Guide

Number of data blocks read.
bpr
Number of data blocks written.
bpw
Number of data blocks decrypted.
bpd
Number of data blocks encrypted.
bpe
Read rate in kilobytes per second (kb/s). This statistic is based on the time it
takes the EVFS pseudo-driver to complete a read request. This statistic includes
the time it takes to read data from the physical disk and the underlying LVM
or VxVM volume (if applicable), and to decrypt the data.
kbpsr
Write rate in kilobytes per second (kb/s). This statistic is based on the time it
takes the EVFS pseudo-driver to complete a write request. This statistic includes
the time it takes to encrypt the data, and write the data to the underlying LVM
or VxVM volume (if applicable) and the physical disk.
kbpsw
Decryption rate in kilobytes per second (kb/s).
dkbps
Encryption rate in kilobytes per second (kb/s).

The following listing shows output from the evfsadm stat -s command:
# evfsadm stat -s
Total EVFS Volumes: 2
364 blocks decrypted
52398 blocks encrypted
2076 blocks read
52494 blocks written
Displaying EVFS Volume Keys and Operating Parameters (evfsvol display)
Use the evfsvol display command to display information about the EVFS volume, including
the following items:
• Key IDs of the owner, recovery, and authorized user keys configured for the EVFS volume
• Name of the underlying LVM, VxVM, or physical volume device file
• Encryption algorithm used to encrypt the volume data
Syntax
evfsvol display [-a|evfs_volume_path]
where:
-a
Displays the EMD information for all enabled EVFS volumes.
evfs_volume_path
Specifies the absolute pathname for the EVFS volume device file, such
as /dev/evfs/vg01/lvol5, /dev/evfs/vx/dsk/rootdg/vol05,
or /dev/evfs/dsk/c2t0d1. The evfsvol utility displays the EMD
information for the volume.
Example
The output for the evfsvol display evfs_volume_path is similar to the following:
# evfsvol display /dev/evfs/vg01/lvol5
EVFS Volume Name: /dev/evfs/vg01/lvol5
Mapped Volume Name: /dev/vg01/lvol5
EVFS Volume State: enabled
EMD Size (Kbytes): 520
Max User Envelopes: 1024
Data Encryption Cipher: aes-128-cbc
Digest: sha1
Owner Key ID: root.rootkey1
Recovery Agent Key IDs: evfs.evfs
Total Recovery Agent Keys: 1
User Key IDs: user1.user1key
Total User Keys: 1
