It's been a while since I've been here ... so here is my two cents worth.
On my site I have 4 lv's across 4 pdisks and these are split across our 4
SSA adaptors, split evenly across the two I/O buses of our system.  I did
the same thing for my disk storage pools as well as it saves a lot of disk
I/O contention (I hope)  I assume either AIX striping or SSA Raid Striping
or whatever....
Sooooo ... My initial reaction is to create the 5 logical volumes across 5
physical disks (ideally spilt across a number of adaptors) define the 5
dbvols across the 5 lvs, (I assume they are striped?).
We are about to re-look this ourselves with a new installation, I'd also
welcome any thoughts on this. ... All in please !

Cheers

Which is best for performance?
Create one AIX logical volume with 5 disk, then define 5 dbvol located in
the one lv.
OR
Create 5 AIX logical volume, 1 lv per disk, then define 5 dbvol - one per lv
.

Thanks for your help.  I am creating a new ADSM server and I want to get it
right this time. :>
