Enclosure loss protection is not valid when you create logical drives on existing subsystems.
The
drawerLossProtect
parameter defines if data on a logical drive is accessible if a drawer fails. When
you assign the drives, if you set the
drawerLossProtect
parameter to
TRUE
and select more than one drive
from any one drawer, the storage subsystem returns an error. If you set the
drawerLossProtect
parameter
to
FALSE
, the storage subsystem performs operations, but the subsystem that you create might not have
drawer loss protection.
You must set the enclosureLossProtect parameter and the drawerLossProtect parameter to the same
value. Both of the parameters must be either TRUE or FALSE . If the enclosureLossProtect parameter and
the drawerLossProtect parameter are set to different values, the storage subsystem returns an error.
Security Type
See “Security Type” on page 4-34 for an explanation of this new parameter.
