[ADSM-L] Lun versus logical volume for DB volumes

Hi,

I've specced a design for a new TSM server and as recommended have
specified multiple luns for the database.  The folklore is that DB2 will
start one thread per lun so for a big database you use 8 luns and hence get
8 threads.

My AIX guy is asking whether I really need 8 luns or will 8 AIX logical
volumes have the same effect.

Does anyone know or can tell me where to look?

Thanks

Steve.
