omconfig storage Commands 251
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 is 500 MB with a stripe size of 16 KB. 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.
To create the virtual disk described in this example, type:
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:
