Remember
ADDVOLUMES(volser [ volser])
This provides the volumes that are to be added to the list of candidate
volumes. You can use ALTER ADDVOLUMES to add candidate volumes to non-managed
VSAM data sets and SMS-managed VSAM, non-VSAM, and generation data sets (GDS).
Only nonspecific volumes can be added to SMS-managed, non-VSAM data sets and
GDS data sets. If an ALTER ADDVOLUMES is done to a data set already opened and
allocated, the data set must be closed, unallocated, reallocated, and reopened
before VSAM can extend onto the newly added candidate volume. Adding a
nonexistent volume to the list can result in an error when the data set is
extended. Ensure that the volume exists and is online before attempting to
extend the data set.
Restriction: This does not work with non-SMS non-VSAM.
SMS might not use candidate volumes for which you request specific volsers with
the ADDVOLUMES parameter. Sometimes a user-specified volser for an SMS-managed
data set results in an error. To avoid candidate-volume problems with SMS, you
can have SMS choose the volser used for a candidate volume. To do this, you can
code an * for each volser that you request with the ADDVOLUMES parameter. If,
however, you request both specified and unspecified volsers in the same
command, you must enter the specified volsers first in command syntax. The
system does not allocate space on candidate volumes until VSAM extends to the
candidate volume. This includes SMS-managed data sets with Guaranteed Space.
