Contiguous devices does not guarantee that the meta will not share spindles.  If the meta has enough members and there are not many drives, you could get sharing anyway.  Thick metas should not share the same drives if at all possible.
Hello, i want to create one meta with 2 members:  what is the best practice: 1/: indicate to symmetrix what dev member it must take for create the meta  form meta from dev XXXX config=striped, stripe_size=2 cyl; add dev YYYY to meta XXXX;  or let the symmetrix take one device member free:  form meta from dev XXXX config=striped, stripe_size=2 cyl, count=2;  thanks
