You must define at least one pool storage group name to SMS, and
at least one volume serial number to this storage group. (A storage
group with no volumes defined is not valid.) This volume serial should
be for a nonexistent volume to prevent the occurrence of JCL errors
from jobs accessing data sets using a specific volume serial number.
Defining a non-existent volume lets you activate SMS without having
any system-managed volumes. No data sets are system-managed at this
time. This condition provides an opportunity to experiment with SMS
without any risk to your data.
Define the storage group in your SCDS:
- Enter a 6 (Storage Group) on the ISMF Primary Option
Menu to view the Storage Group Application Selection panel, shown
in Figure 1.

Minimal Configuration Panel Utilities Help

- Specify values for the CDS Name and Storage Group
Name fields. The CDS name must be the same name that you specified
for the SCDS on the CDS Application Selection panel (see Figure 1). In this example, the CDS
name is USER6.MYSCDS and the storage group name is SG2.
Enter

SCDS
Name and Storage Group Name are output fields containing the values
that you specified on the Storage Group Application Selection panel
(see Figure 1). Description is an optional
field of 120 characters that you can use to describe the storage group
type.
If
you supply the name of a Parallel Sysplex® in the Migrate System Name, Backup System Name, or Dump
System Name field, make sure you enter it correctly. Otherwise, the
expected operation might not occur.
- Let the storage group attributes default to the ISMF
values.
