Allocating Space across Generic Volumes
Cross-volume allocation, in conjunction with the AVR facility, is used when it is
desirable to allocate disk space from a group of disk packs. These disk packs
are scanned generically in PUB order to determine the proper device address.
CA Dynam/D searches for a certain group of volume serial numbers, or all the
volume serial numbers defined in the PUB table. (The PUB table describes all
of the devices defined for the operating system.)
To request cross-volume allocation, enter from one to six asterisks (*) on the
EXTENT statement or in the Catalog for the volumes you want referenced. The
number of asterisks you specify within the serial number parameter will
determine the scope of the generic search.
Shown below is the format for specifying each of the six possible methods of
cross-volume allocation:
// EXTENT SYSnnn,vvvvv*
vvvv**
vvv***
vv****
v*****
******
If you specify a volume serial number (volser) of less than six characters and
ending with an asterisk, CA Dynam/D will left-justify the volser and pad
additional asterisks to construct the full six-character volser.
