Z^DEVNAME^OFF

Z^DEVNAME^DATA

Considerations
• It is possible for CONFIG_GETINFO_BYLDEV2_ to return an error value of 0D (information
successfully returned) while the I/O subsystem reports an error in the Z^LOGICAL^STATUS
field of the returned buffer. In that case, the error value of 0D indicates that communication
with the I/O subsystem was successful, while the I/O subsystem logical status value reflects
the status of the I/O subsystem.
• Searching logical devices
To perform a search of logical devices, call the file-name inquiry procedures:
FILENAME_FINDSTART_, FILENAME_FINDNEXT[64]_, and FILENAME_FINDFINISH_.
