omconfig storage Commands 261

Example Syntax

You can create a RAID-5 virtual disk of 500MB with a stripe size of 16 KB on a

PERC 3/QC controller. The name of the virtual disk is vd1 and it resides on

connector 0 of controller 1. Because the virtual disk is 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. The virtual disk has

read-ahead,

write–through caching, and cache I/O policies.

To create a virtual disk:

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. For

more information on read, write, and cache policies are supported by the

controller, see the Dell OpenManage Online Help.

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, type:

omconfig storage controller action=setrebuildrate

controller=1 rate=50
