T10PI
Notes
The drives parameter lets you choose the number of disk drives that you want to use in the subsystem.
If you choose this option, you do not need to specify the disk drives by enclosure ID and slot ID. The
controllers choose the specific disk drives to use for the subsystem.
If you do not specify a capacity by using the capacity parameter, all of the disk drive capacity that is
available in the subsystem is used. If you do not specify capacity units, bytes is used as the default
value.
Description
The type of drive that you want to use in the subsystem.
You cannot mix drive types.
You must use this parameter when you have more than
one type of drive in your storage subsystem.
Valid drive types are :
v fibre
v SATA
v SAS
If you do not specify a drive type, the command defaults
to fibre.
The setting to enforce enclosure loss protection when
you create the subsystem. To enforce enclosure loss
protection, set this parameter to TRUE. The default value
is FALSE.
The setting to enforce drawer loss protection when you
create the mirror repository logical drive. To enforce
drawer loss protection, set this parameter to TRUE. The
default value is FALSE.
The setting to specify the security level when creating
the subsystems and all associated logical drives. These
settings are valid:
v none – The subsystem and logical drives are not
secure.
v capable – The subsystem and logical drives are capable
of having security set, but security has not been
enabled.
v enabled – The subsystem and logical drives have
security enabled.
The setting to specify that an subsystem, and the logical
drives within the subsystem, has T10 PI (Protection
Information) to help you ensure that the data maintains
its integrity. When you use this parameter, only
protected drives can be used for the subsystem. These
settings are valid:
v none—The subsystem does not have T10 PI
(Protection Information).
v enabled—The subsystem has T10 PI (Protection
Information). The subsystem support is protected
information and is formatted with protection
information enabled.
