A PERC 4 raid 10 question.
We have 2 PE1750's with PERC 4 DC and a powervault 220s. I have split
it via the slider switch at the
back to make 2 X 7.ie Each pe1750 access 7 disk independant of each other.
They will be dbase servers running mysql on rh es3.
The aim is to run each as raid 1+0 (mirror then stripe).
ie: Mirror 2 pairs, then stripe across them.
The disks are 70G each .
Now I ran trough a raid 10 setup with a helpful dell rep, and
I think I got the massage accross that I wanted raid 1+0 not
He asked me to setup ths disks like this
I can see that the final disk size is approx 140G, visible as /dev/sdb
according my boot log (dmesg).
My question is:
How can I confirm that I have raid1+0 and not raid 0+1 ?
I dont want to find out later ??
Thanks / Frank
