CLI Guide

The only parameters that require specification are for the controller, RAID level, virtual disk size, and physical disk selection. Storage
Management supplies default values for all other unspecified parameters. For more information on read, write, and cache policies that are
supported by the controller, see the Dell EMC OpenManage Online Help.
Parameter specification for creating and reconfiguring virtual disk
The following table displays how to specify the omconfig storage controller action=createvdisk parameters:
Table 158. Parameters And Types
Parameters Type
controller=id Required
raid=<c | r0 | r1 | r1c | r5 | r6 | r10 | r50 | r60> Required
size=<number | max | min> Required
pdisk=<connector:targetID,connector:targetID,.....> Required
[stripesize=<2k b| 4kb | 8kb | 16kb | 32kb | 64kb | 128kb>] Optional
[cachepolicy=<d | c>] Optional
[readpolicy=<ra | nra | ara | rc | nrc>] Optional
[writepolicy=<wb | wt | wc | nwc | fwb>] Optional
[name=<string>] Optional
[spanlength=<n>] parameter Optional
NOTE: On PERC S140, the maximum virtual disk configuration is 16 and monitoring is 30.
controller=id parameter
Specify the controller ID as reported by the omreport storage controller command. For example,controller=2
raid=<c | r0 | r1 | r1c | r5 | r6 | r10 | r50 | r60>
Use the raid=<c | r0 | r1 | r1c | r5 | r6 | r10 | r50 | r60> parameter to specify a RAID level for a virtual disk. Different controllers support
different RAID levels. For more information about RAID levels a controller supports and for general information about RAID levels, see the
Dell EMC OpenManage Online Help. The following table displays how to specify the raid=n parameter for each RAID level.
Table 159. Raid level and parameter specification
RAID Level raid=n Parameter Specification
RAID-0 raid=r0
RAID-1 raid=r1
RAID-5 raid=r5
RAID-6 raid=r6
RAID-10 raid=r10
RAID-50 raid=r50
RAID-60 raid=r60
size=<number | max | min>
The following table displays how to specify the size=<number | max | min>
Table 160. Size Parameter
size=<number | max | min> Parameter Specification Description
size=<n> Use this specification to indicate a specific size for the virtual disk.
The virtual disk size is specified in b (bytes), m (megabytes), or g
(gigabytes). For example, size=500m indicates that the virtual
disk is 500 MB.
