Parameter Description
logicaldriveWWN
The world wide name of the logical drive that
you want to recover. The name is a 16-byte
identifier, for example,
60080E500017B4320000000049887D77. Enclose the
identifier in double quotation marks (“ ”).
capacity
The size of the logical drive that you are adding
to the storage subsystem. Size is defined in units
of bytes,
KB
,
MB
,
GB
, or
TB
.
offset The number of blocks from the start of the
subsystem to the start of the referenced logical
drive.
raidLevel The RAID level of the subsystem that contains
the disk drives. Valid values are
0
,
1
,
3
,
5
, or
6
.
segmentSize
The amount of data (in KB) that the controller
writes on a single disk drive in an subsystem
before writing data on the next disk drive. Valid
values are
8
,
16
,
32
,
64
,
128
,
256
, or
512
.
dssPreallocate
The setting to turn on or turn off allocating
logical drive storage capacity for future segment
size changes. To turn on allocation, set this
parameter to
TRUE . To turn off allocation, set this
parameter to
FALSE
.
SSID
The storage subsystem identifier of a logical
drive. Use the
show logical drive command to
determine the storage subsystem identifier.
owner
The controller that owns the logical drive. Valid
controller identifiers are
a
or
b
, where
a
is the
controller in slot A, and
b
is the controller in slot
B. If you do not specify an owner, the controller
firmware determines the owner.
cacheReadPrefetch
The setting to turn on or turn off cache read
prefetch. To turn off cache read prefetch, set this
parameter to
FALSE . To turn on cache read
prefetch, set this parameter to
TRUE
.
T10PI
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.
Notes
The storage management software collects recovery profiles of the monitored storage subsystems and
saves the profiles on a storage management station.
