SSH to the iDRAC of the machine:
Enter RACADM:
Check for existing RAID volumes:
Check ID:s of the physical disks and the controller:
Create the RAID volume:
In this case RAID6 with read-ahead and write-back switched on
Schedule the job (Note: Also see altenative method below):
Execute the job by powercycling the server:
ALTERNATIVE: Schedule the job without reboot:
If the RAID controller supports realtime execution, the virtual disk can be created without the need to reboot. To do this, add “–realtime” after the job creation command as follows:
Verify RAID volume creation after job has completed:
Note: You don’t need to powercycle. You can simply do, eg:
racadm jobqueue create RAID.Integrated.1-1 –realtime
Worked for me on a Dell R640.
And that’s a double hyphen (aka “minus sign”) in front of the “realtime”.
That’s an excellent point, thank you. This will depend on whether the RAID controller supports the “realtime” feature, but most of them do. Post updated.
