IBM System Storage DS3000 User Manual

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.IftheenclosureLossProtect 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.
