You can display a storage
group’s status in each system in
the SMS complex by using the LISTSYS line operator in ISMF. The storage
group must be a pool type, and it must be part of the active configuration.
Perform the following steps to display a storage
group's status.
- Display the Storage Group Application Selection
panel (select
option 6 from the ISMF Primary Option Menu for storage administrators).
_______________________________________________________________
- Supply values to create a list of storage groups. For example,
you could use the following to create a list of storage groups with
names that begin with SGNAME:
- CDS Name: 'ACTIVE'
- Storage Group Name: SGNAME*
- Option:
1, List. This displays the Storage Group List panel.
_______________________________________________________________
- Type LISTSYS in the Line Operator column next to the desired pool
type storage group on the Storage Group List panel. This shows the
SMS Storage Group Status Display.
Requirement: If a volume has been
initialized with LABEL as an SMS device,
the storage group must be defined in the active configuration in order
for space information to be displayed when the LISTSYS line operator
is issued.
Note: The information provided by LISTSYS differs
from that
provided by LISTVOL, because the information for the two commands
comes from different sources.

all the online volumes belonging to storage group SGNAME01, of all
the volumes that have a status of ENABLE.
