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 -aevfs_volume_pathwhere:

-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.
