Verifying the EMD (evfsvol check)
The evfsvol check command verifies the integrity of the EMD for an encrypted volume. You
must disable the EVFS volumes you want to check before executing the evfsvol check
command.
If the verification fails, you can use the evfsvol restore command to restore the previous
version of the EMD. See “Recovering from EMD Corruption” (page 89) for more information.
Syntax
evfsvol check -a|evfs_volume_path
where:
-a Checks the EMD for all EVFS volumes in the /etc/evfs/evfstab
file.
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 verifies the EMD
for the volume. EVFS must be disabled for the volume.
Example
In the following example, the user verifies the EMD for the /dev/evfs/vg01/lvol5 volume:
# evfsvol check /dev/evfs/vg01/lvol5
Encrypted volume "/dev/evfs/vg01/lvol5" status: OK
Encrypted volume "lvol5" has been successfully checked.
