Displaying Information
With location-independent naming, the file \SYSA.$DATA00.CURRENT.OVERDUE can
reside on any physical volume. With the exception of the node name, the name of the
file managed by SMF is independent of its location.
SMF controls the mapping of the external name to the internal name. The internal
name, which identifies the file’s physical location, can change when a file is moved to a
different location, while the external name remains the same to applications.
Displaying Information
To display information about virtual disks:

Displaying Configuration Information for Virtual Disks
The INFO DISK Command (page 14-105) displays information about a virtual disk, as
recorded in the system configuration database.
Considerations for INFO DISK and Virtual Disks
•
If the SMF master process ($ZSMS) is not started, the Configuration State in the
INFO report shows that the “SMF master process is Down.”
•
If a configuration record for a virtual disk exists, but the SMF master process does
not have a definition for it, no information is displayed for attribute values that are
supplied by the SMF master process (the Configuration State in the INFO report
displays “No Definition with SMF master process”).
