Using omconfig to add a RAID 1 device for a Perc 6/i Dell Raid Controller

So, I’ve been provisioning disks, and stuff recently.. this is how I did it on a Dell. Quite an easy thing to do!

omconfig storage controller action=createvdisk controller=0 raid=r1 size=max readpolicy=ara pdisk=0:0:2,0:0:3
Command successful!

In this case the two disks newly added were 0:0:2 and 0:0:3 on the SAS ‘bus’.

An additional primary partition was created and added for this device sdb1, and a filesystem of the same kind (ext3) as the system disk was created;

 mkfs.ext3 /dev/sdb1

mke2fs 1.39 (29-May-2006)
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

You will naturally need to mount the partition and create an fstab entry to make this permanent;

mount /dev/sdb1 /mnt/backup

echo "/dev/sdb1               /mnt/backup             ext3    defaults        1 1" >> /etc/fstab

You may wish to consider adding the above to fstab manually. It’s not a good idea using echo with it incase you make a mistake ;-D

Best wishes,
