To display information about storage subsystem devices and processes, see:
•
The SCF INFO Command on page 14-104
•

LISTDEV Information for the Storage Subsystem
You can use the SCF LISTDEV command to display configured information about
processes that have a device type and that are known to SCF.
For these storage subsystem devices, you can specify an existing ldev number in any
storage subsystem command (unless the command has a path specification):
•
The $ZZSTO storage subsystem manager
•
Disks (magnetic and virtual)
•
Tape drives
•
Open SCSI devices
•
Storage pools
•
The $ZSMS SMF manager
•
The $ZSLM or $ZSLM2 SCSI lock manager
These devices are assigned an LDEV number in the order in which they were
configured and as recorded in the destination control table.
