Summary: How to RAID1+0 with Solaris 9 SVM

Thanks for all who responded to me, especially Mike, mikelist@sky.net, 
who pointed out that he asked the same question and posted a summary 
last month. More info will be found in his summary. Sorry for missing 
that and resending the question.

In short:

Q: How to set up RAID1+0 using Solaris Volume Manager
A: Just set up RAID 0+1, using same number of stripes and stripes of 
same size, the software will set up RAID1+0, and won't tell you it did! 
There is no way to ensure what you built was RAID1+0 and not 0+1, except 
from unplugging disks. dirk.boenning@ccf.de said he tested it himself.

This behaviour is not documented anywhere, apart from the few sentences 
in SVM user guide that I pasted in my original post.

alexei@soemail.rutgers.edu got me excited suggesting that A5000 have 
hardware RAID cards built in.... It turns out that is not correct, A5x00 
do not have hardware RAID.

One response, rich.teer@rite-group.com,  claimed that what I configured 
was really RAID 0+1... I am not willing to unplug my disks right now in 
order to verify , I just hope he is wrong :)


Thank you all,

Mohamed~
