EMD Is Dirty
Symptom
The evfsvol enable or evfsvol check command fails. The output from the evfsvol
enable command includes the text EMD is dirty and is similar to the following:
evfsvol: enable error: cannot enable encrypted volume "/dev/evfs/vg01/lvol5", EMD is dirty
evfsvol: enable error: failed to enable encrypted volume /dev/evfs/vg01/lvol5
The output from the evfsvol check command includes the text EMD is dirty and is similar
to the following:
evfsvol: check error: cannot check encrypted volume "ev1", EMD is dirty
Description
If the system terminates without executing the system shutdown scripts, EVFS volumes will
have a "dirty bit" set in the EMD areas. If you try to enable an EVFS volume with the dirty bit
set, EVFS displays the message EMD is dirty.
Solution
Use the following evfsvol check -r command to reset the dirty bit.
evfsvol check -r -a|evfs_volume_path
where:
-r
Resets the dirty bit for the specified volume.
-a Resets the dirty bit for all 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.
