Considerations—ServerWare SMF
management with logical files, virtual volumes, and storage pools. On any ServerWare
SMF node, logical files, virtual volumes, and storage pools can coexist with
conventional Guardian files and volumes. In the context of ServerWare SMF,
conventional Guardian files and volumes are called direct files and direct volumes.
With ServerWare SMF, NonStop SQL objects can be either direct or logical files. A
logical file is a file that resides on a virtual volume; a virtual volume is actually a
process that uses a pool of physical volumes for storage. When you create an SQL
object on a virtual volume, the object is a logical file, and you always refer to it by
logical name. The object can be located on any physical volume in the storage pool for
the virtual volume you specify; ServerWare SMF automatically determines the best
location.
Considerations—ServerWare SMF
Most NonStop SQL CREATE and ALTER statements have either syntax changes or
considerations for ServerWare SMF. Syntax changes consist of a new option,
PHYSVOL, which allows you to place an SQL object on a particular physical
volume associated with the specified virtual volume. Some NonStop SQL/MP utility
commands are also affected, as are temporary table and file placement.
