172 Using the Storage Management Service

Example Syntax

For example, you may want to create a RAID-5 virtual disk on a PERC 3/QC

controller. See the Dell OpenManage Online Help for information on read,

write, and cache policies are supported by this controller. For example, to

create a virtual disk with the following read, write, and cache policy:

• Read-ahead

• Write–through caching

•Cache I/O

The virtual disk will be 500 MB with a stripe size of 16 KB. The name of the

virtual disk will be vd1 and it will reside on connector 0 of controller 1.

Because the virtual disk will be a RAID-5, it requires at least three physical

disks. In this example, you specify four physical disks. These are physical

disks 0 through 3.

To create the virtual disk described in this example, enter:

omconfig storage controller action=createvdisk

controller=1 raid=r5 size=500m pdisk=

0:0,0:1,0:2,0:3 stripesize=16kb cachepolicy=c

readpolicy=ra writepolicy=wt

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.

omconfig Set Controller Rebuild Rate

Use the following omconfig command syntax to set the controller rebuild rate:

Complete Syntax

omconfig storage controller action=setrebuildrate

controller=id rate=<0 to 100>

where id is the controller ID as reported by the omreport storage controller

command.

Example Syntax

To set the rebuild rate to 50 on controller 1, enter:

omconfig storage controller action=setrebuildrate

controller=1 rate=50
