| Name | Type | Required | Default | Constraint | Description |
|---|---|---|---|---|---|
controlid | - | Yes | - | Type: Range; 0, 255 | -v <RAID Controller ID> The RAID controller on which logical drive will be created. It is mandatory. |
raidlevel | - | Yes | - | - | -rl <r0│r1│r5│r6│r10│r50│r60> Logical drive RAID level. It is mandatory. When '-cachecade' is specified, RAID level 0/1 is valid. r0 = RAID0 r1 = RAID1 r5 = RAID5 r6 = RAID6 r10 = RAID10 r50 = RAID50 r60 = RAID60 |
pdid | - | Yes | - | Regex | -pd <PD ID separated by commas> Physical drives ID participated in this logical drive, seperated by commas. It is mandatory. |
cachecade | - | No | - | Type: Enum; Enum: 0, 1 | -cachecade Logical drive is used for secondary cache. It is optional. It must be supported by RAID controller first. |
spannum | - | No | - | - | -sc <Span Count> Logical drive span count. 8 is maximum. It will be 1 on RAID0/1/5/6 and 2 on RAID10/50/60 by default. |
ldname | - | No | - | Type: Length; Min: None; Max: 15 | -name <LD name> Logical drive name. 15 ASCII characters is maximum. It is optional. The value can't be same as the options if it starts with '-'. |
ldsize | - | No | - | Regex | -size <LD size>{m│g│t} The size of logical drive and the uint can be 'm'(megabytes) , 'g'(gigabytes) , 't'(terabytes). It is optional. If this option is not specified, the size of logical drive depends on the usable size of each array. |
stripesize | - | No | - | Type: Enum; Enum: 16K, 32K, 64K, 128K, 256K, 512K, 1M, 255 | -ss <64K│128K│256K│512K│1M> Logical drive strip size. The recommended range is 64K ~ 1M. It is optional. The default of strip size is '256K'. |
rpvalue | - | No | - | Type: Enum; Enum: ra, nra, 255 | -rp <ra│nra> Logical drive read policy. It is optional. The default of read policy is 'Read Ahead'. ra = Read ahead nra = No Read ahead |
wpvalue | - | No | - | Type: Enum; Enum: wt, wbwithbbu, wb, 255 | -wp <wt│wbwithbbu│wb> Logical drive write policy. It is optional. the default of write policy is 'Write Back with BBU'. wt = Write through wbwithbbu = Write back with BBU wb = Write back |
iopvalue | - | No | - | Type: Enum; Enum: cio, dio, 255 | -iop <cio│dio> Logical drive IO policy. It is optional. The default of IO policy is 'Direct IO'. cio = Cached IO dio = Direct IO |
apvalue | - | No | - | Type: Enum; Enum: rw, ro, blocked, 255 | -ap <rw│ro│blocked> Logical drive access policy. It is optional. The default of access policy is 'Read Write'. rw = Read write ro = Read only blocked = Blocked |
dcpvalue | - | No | - | Type: Enum; Enum: enabled, disabled, default, 255 | -dcp <enabled│disabled│default> Logical drive disk cache policy. It is optional. The default of disk cache policy is 'Enabled'. enabled = Enable disk cache disabled = Disable disk cache default = Unchanged and determined by disk type |
initmode | - | No | - | Type: Enum; Enum: no, quick, full, rpi, opo, 255 | -init <no│quick│full> Logical drive init type. It is optional. The default of init type is 'None'. no = Don't initialize the logical drive quick = Quickly initialize the logical drive full = Fully initialize the logical drive |
AccelerationMethod | - | No | - | Type: Enum; Enum: no, cache, iobypass, 255 | -acc <no│cache│iobypass> Logical drive acceleration method. It is optional and not involved when '-cachecade' is specified. |
AssociateLd | integer | No | - | Type: Range; 0, 65535 | -associatedld <LD ID> General Logical Drive ID associated with cachecade. It is mandatory when '-cachecade' is specified |
CacheLineSize | - | No | - | Type: Enum; Enum: 64K, 256K | -cls <64K│256K> Cache Line Size. It is optional and not involved when '-cachecade' is not specified. If this option is not specified, the default of cache line size is 64K. |
