: Encryption information.
¢
Enabled: The parity group encryption to which
LDEV belongs is enabled, or a V-VOL is associated
with a pool in which a pool volume has encryption
enabled.
¢
Disabled: The parity group encryption to which
LDEV belongs is disabled, or a V-VOL is associated
with a pool in which a pool volume has encryption
disabled.
¢
Mixed: The pool to which the LDEV belongs
contains both pool volumes for which encryption is
enabled and pool volumes for which encryption is
disabled.
Note: Encryption of data is not ensured in an LDEV
with the Mixed encryption status. To manage data
encryption, use an LDEV for which Encryption is
Enabled or Disabled.
A hyphen (-) is displayed for an external volume. For
DP-VOLs, the pool to which the LDEV belongs is either
an external volume or blocked.
