HP UX Encrypted Volume and Filesystem (EVFS) manual Evfsvol disable Fails, Evfs Volume Is Busy

Description

The evfsvol create command fails if an EMD already exists on the volume. This can occur if you reuse an EVFS volume without destroying the previous EMD.

Solution

If you are reusing an EVFS volume and do not want to recover the existing data, re-enter the evfsvol create command with the -foption. The evfsvol create command generates a new volume encryption key and new EMD. Any existing data is irrecoverable.

If you want to retrieve data from an existing EVFS volume and have problems with the existing EMD, use the procedure described in “Recovering from EMD Corruption” (page 89).

evfsvol disable Fails, EVFS Volume Is Busy

Symptom

The evfsvol disable command returns the following error:

evfsvol: disable error: cannot disable encrypted volume “evfs_volume_path”, evol is busy

Description

EVFS does not disable an EVFS volume if the volume is in use.

Solution

Terminate any processes that are accessing the volume. You can use the fuser -cucommand to determine the processes accessing files, and the fuser -ckucommand to terminate the processes. See fuser(1M) for more information.

If the data is used by system processes, you might need to terminate the processes by changing the system runlevel to single-user level with the shutdown utility. See shutdown(1M) for more information.

If the volume has a file system mounted, unmount the file system. See umount(1M) for more information.

evfsadm map Fails, Invalid Device

Symptom

The evfsadm map command returns the following error:

evfsadm: map error: invalid volume block device “filename” For example:

evfsadm: map error: invalid volume block device “/dev/vg01/rlvol5”

Description

The command evfsadm map requires the name of a volume block device file as input. The evfsadm utility maps the volume block device file to EVFS and automatically maps the corresponding volume character (raw) device file to EVFS.

Solution

Specify a valid volume block device file. In the previous example, the user must replace /dev/vg00/rlvol5 with /dev/vg00/lvol5.
