This parameter specifies the parmlib member, IGDSMSxx,
from which the storage management subsystem (SMS) will obtain its
options when the system is initialized for partitioned data set extended
(PDSE) support. The two alphanumeric characters, represented by xx,
are appended to IGDSMS to name the member. NIP saves the name until
SMS is initialized. If initialization of PDSE support fails, the IGDSMSxx
parmlib member is selected from the IEFSSNxx parmlib member by using
the ID=xx keyword (for detailed information, see IGDSMSxx (storage management subsystem definition)). Value Range: Any two
alphanumeric characters.
Default Value: 00 (Specifies
IGDSMS00, the IBM-supplied default parmlib member)
