EVFS Tasks and Commands

The following tables provide the command syntax for common EVFS administrative tasks.

Table B-1 Starting and Stopping EVFS

Task	Command
Start the EVFS subsystem.	evfsadm start [-n number_threads]
Stop the EVFS subsystem.	evfsadm stop

Table B-2 Managing EVFS Volumes

Task	Command
Map an LVM, VxVM, or physical	evfsadm map volume_path
volume to EVFS and create EVFS
device files.
Unmap an EVFS volume.	evfsadm unmap evfs_volume_path
Create an EVFS volume (generates	evfsvol create [-k keyname] [-f] evfs_volume_path
a volume encryption key and creates
the EMD).
Destroy an EVFS volume (you must	evfsvol destroy [-f] evfs_volume_path
be the volume owner, and the data
will be irrecoverable).
Enable an EVFS volume without a	evfsvol enable [-kkeyname] evfs_volume_path
stored passphrase.
Enable an EVFS volume with a	evfsvol enable -p evfs_volume_path
stored passphrase and key ID in
/etc/evfs/evfstab.
Enable all EVFS volumes with key	evfsvol enable -a
IDs in /etc/evfs/evfstab.
Disable an EVFS volume without a	evfsvol disable [-kkeyname] evfs_volume_path
stored passphrase.
Disable an EVFS volume with a	evfsvol disable -p evfs_volume_path
stored passphrase and key ID in
/etc/evfs/evfstab.
Disable all EVFS volumes with key	evfsvol disable -a
IDs in /etc/evfs/evfstab.
Inline Encrypt data on an existing	evfsvol iencrypt [-f] [-k keyname] [-c cipher]
volume	evfs_volume_path
Open raw access for an EVFS	evfsvol raw [-kkeyname] evfs_volume_path
volume.
CAUTION: HP recommends that
you use this operation only when
creating encrypted backup media or
restoring encrypted backup media,
as described in “Backing Up EVFS
Volumes” (page 102).
Close raw access for an EVFS	evfsvol close [-kkeyname] evfs_volume_path
volume.
