It builds the raid but the total amount of disk space is that of the 9.1GB
disks only.

Not sure if its possible to do, but I could see many potential problems of
doing it that way since your are mirroring your striped filesystems. In
context of just pure mirroring would you mirror a larger drive onto a
smaller drive?....well it can be done I guess (from AIX at least) but you
would be limiting the effectiveness to the size of your smallest drive.

Are you considering software/hardware mirroring?

Guru's,

A little advise please....

I am setting up a RAID10 config on a H80, there are 8 x 36.4GB SSA disks and
8 x 9.1GB SSA Disks, the question is ..is it OK to use the 36.4 GB disk as
the Primary and the 9.1GB Disks as the secondary?

Thanks
